The day on the hill

On Sgùrr Fhuaran: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze).

Cloud & views

Cloud base around 600–900 m in the morning, lifting to 1000–1300 m around midday. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Cloud may hang lower on northwestern slopes and lift somewhat on the southeastern side, but local terrain can differ. Sunny spells are possible away from summit cloud, but may not reach the top while it is in cloud.

Rain & temperature

Little or no rain is forecast. Cold on exposed tops: air temperature broadly 0 to 4°C, feeling around -6 to -2°C in the wind.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

Cloud-height uncertainty could put the summit in or out of cloud, even where forecasts agree on the wider cloud cover.

Cloud-free timing: Around 5% early, improving to around 45% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 3.9 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Full overnight outlook

Open-hillside camping looks mixed overall around 600 m (59/100). A lower pitch near 300 m looks more comfortable. Conditions are less suitable by 900 m. Open-ground gusts may reach about 35 mph. Seek meaningful shelter. Peak gusts range from about 25 mph at 300 m to 35 mph at 900 m. Wind direction may change substantially during the night. Shelter that works at dusk may be less effective later. Little overnight rain is forecast. Pitches near 900 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. The coldest temperature falls from about 5.9°C at 300 m to 4.1°C at 900 m.

Warmth planning: As a broad starting point, consider a 3-season bag with an ISO/EN comfort rating at or below about 2°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Full climbing & scrambling outlook

Conditions for exposed scrambling look mixed (45/100). Recent rain may leave seepage and damp rock, especially on shaded sections. The mapped summit rock is Psammite and semipelite (Morar Group). Dry quartz-rich bands can be grippy, while mica-rich or foliated sections, lichen and vegetation may become slippery when wet. Representative samples along available mapped routes also include Psammite, Pelite, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

Strong gusts on Sgùrr Fhuaran: summit wind broadly 35-50 mph, with gusts 60-70 mph at times (gale-force mean winds at times).

Things to watch

Possible spate risk from the afternoon into the night, with forecast rain and subsequent runoff. Risk may continue beyond the daytime period shown. Timings are approximate, not a guarantee of safe crossings afterwards. Burns and unbridged crossings may rise quickly. Turn back if a crossing looks unsafe.

Wind & exposure

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops.

Cloud & views

Cloud base around 1500–1800 m in the morning, lowering to 1600–1900 m around midday and 900–1200 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Cloud may hang lower on southern slopes and lift somewhat on the northern side, but local terrain can differ. Sunny spells are possible away from summit cloud, but may not reach the top while it is in cloud.

Rain & temperature

Some rain is likely, totalling around 5-10 mm, but its timing and local amounts are uncertain. Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind.

Forecast models differ on summit wind strength: around 32-53 mph at walker height, with gusts 44-74 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

If clothing gets wet, you can cool more quickly. Keep a dry warm layer protected.

The strongest gusts could knock you over on exposed ground. Avoid exposed ridges and edges.

Rain could reach the main walking period or hold off until later. Forecast models disagree on the timing.

Cloud-free timing: Around 95% early, falling to around 25% later.

The day on the hill

A wet day with extensive summit cloud on Sgùrr Fhuaran: summit wind broadly 25-35 mph, with gusts 40-50 mph at times (strong winds). Visibility may drop briefly in showers.

Wind & exposure

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops.

Cloud & views

Cloud base around 700–1000 m through the morning, lifting to 900–1200 m by late afternoon. Summit cloud is likely, but brief clear spells remain possible if the cloud sits higher than expected.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Cloud may hang lower on southwestern slopes and lift somewhat on the northeastern side, but local terrain can differ. Any sunshine may be confined to lower ground or breaks away from the summit.

Drizzle is forecast for much of the day, with some passing showers too. The forecast total is around 5-10 mm, but local amounts will vary.

Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind. Forecast models differ on summit wind strength: around 22-36 mph at walker height, with gusts 30-50 mph.

Rain & temperature

The ground is likely to be wet after recent rain.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

If clothing gets wet, you can cool more quickly. Keep a dry warm layer protected.

Buffeting may affect balance on exposed ground, particularly near ridges and edges. Summit wind could be roughly 22-36 mph, which changes how difficult exposed walking may feel.

The day on the hill

Strong gusts and frequent summit cloud on Sgùrr Fhuaran: summit wind broadly 30-50 mph, with gusts 55-65 mph at times (gale-force mean winds at times). Visibility may drop briefly in showers.

Things to watch

Possible spate risk through the day and overnight, with forecast rain and subsequent runoff. Risk may continue beyond the daytime period shown. Timings are approximate, not a guarantee of safe crossings afterwards. Burns and unbridged crossings may rise quickly. Turn back if a crossing looks unsafe.

Wind & exposure

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Summit wind strength is uncertain: around 28-56 mph at walker height, with gusts 39-78 mph.

Check again nearer the time.

Cloud & views

Cloud base around 500–800 m in the morning, then around 900–1200 m around midday and 700–1000 m by late afternoon. Summit cloud is likely, but brief clear spells remain possible if the cloud sits higher than expected.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Cloud may hang lower on southwestern slopes and lift somewhat on the northeastern side, but local terrain can differ. Any sunshine may be confined to lower ground or breaks away from the summit.

Drizzle is forecast for much of the day, with some passing showers too. The forecast total is around 10-20 mm, but local amounts will vary.

Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -6 to -2°C in the wind.

Rain & temperature

The ground is likely to be wet after recent rain.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

If clothing gets wet, you can cool more quickly. Keep a dry warm layer protected.

The strongest gusts could knock you over on exposed ground. Avoid exposed ridges and edges.

Summit wind could be roughly 28-56 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Best around midday at about 25%, compared with around 5% early and 10% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 5 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Full overnight outlook

Exposed camping is not recommended near 300, 600 and 900 m: gusts may reach about 65 mph. Sustained winds may reach about 45 mph at times. Choose an alternative off the exposed hill. Do not rely on finding shelter after setting out. Open-hillside camping looks very poor overall around 600 m (9/100). Peak gusts range from about 45 mph at 300 m to 65 mph at 900 m. Roughly 22.8 mm is forecast overnight, with rain liable to affect both pitching and packing up. Pitches near 600 and 900 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. Condensation risk is high near 600 and 900 m. Ventilation will matter. The coldest temperature falls from about 8.5°C at 300 m to 5.5°C at 900 m.

Warmth planning: As a broad starting point, consider a 3-season bag with an ISO/EN comfort rating at or below about 4°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look very poor (0/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Psammite and semipelite (Morar Group). Dry quartz-rich bands can be grippy, while mica-rich or foliated sections, lichen and vegetation may become slippery when wet. Representative samples along available mapped routes also include Psammite, Pelite, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 60 mph. Crosswinds can make exposed ridges substantially more serious. Cloud may also make route-finding and retreat harder.

The day on the hill

A wet day with extensive summit cloud on Sgùrr Fhuaran: summit wind broadly 20-35 mph, with gusts 35-45 mph at times (strong winds).

Things to watch

Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops.

If a thunderstorm develops, sudden gusts and heavy rain can change conditions quickly. High spate risk through much of the day and into the night, with recent and forecast rain and subsequent runoff. Risk may continue beyond the daytime period shown. Timings are approximate, not a guarantee of safe crossings afterwards. Burns and unbridged crossings may become difficult or impassable. Turn back if a crossing looks unsafe.

Wind & exposure

Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops.

Cloud & views

Cloud base around 600–900 m in the morning, then around 900–1200 m around midday and 600–900 m by late afternoon. Summit cloud is likely, but brief clear spells remain possible if the cloud sits higher than expected.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Cloud may hang lower on southwestern slopes and lift somewhat on the northeastern side, but local terrain can differ. Any sunshine may be confined to lower ground or breaks away from the summit.

Drizzle is forecast for much of the day, with some passing showers too. The forecast total is around 2-5 mm, but local amounts will vary.

Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind. Forecast models differ on summit wind strength: around 17-33 mph at walker height, with gusts 24-46 mph.

Rain & temperature

The ground is likely to be wet after recent rain.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

If clothing gets wet, you can cool more quickly. Keep a dry warm layer protected.

Buffeting may affect balance on exposed ground, particularly near ridges and edges. A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Best around midday at about 20%. Lowest early at about 10%.

The day on the hill

Strong gusts on Sgùrr Fhuaran: summit wind broadly 40-60 mph, with gusts 70-80 mph at times (storm-force mean winds at times). Visibility may drop briefly in showers.

Wind & exposure

Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Cloud-height uncertainty could put the summit in or out of cloud.

Clear spells may be difficult to time.

Cloud & views

Cloud may hang lower on southeastern slopes and lift somewhat on the northwestern side, but local terrain can differ. Drizzle is forecast for much of the day, with some passing showers too.

The forecast total is around 2-5 mm, but local amounts will vary. Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -6 to -2°C in the wind.

Forecast models disagree markedly on summit wind strength. Check again nearer the time.

Rain & temperature

The ground is likely to be wet after recent rain.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Keep windproof and warm layers readily available.

If clothing gets wet, you can cool more quickly. Keep a dry warm layer protected.

The strongest gusts could knock you over on exposed ground. Avoid exposed ridges and edges.

Overall confidence is unavailable: insufficient comparable wind, rain guidance.

0 is the bottom of the scale. Use the hazard details to judge how severe conditions could be.

Cloud-free timing: Around 10% early, improving to around 85% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 5.9 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Full overnight outlook

Exposed camping is not recommended near 300, 600 and 900 m: gusts may reach about 80 mph. Sustained winds may reach about 55 mph at times. Choose an alternative off the exposed hill. Do not rely on finding shelter after setting out. Open-hillside camping looks very poor overall around 600 m (0/100). Peak gusts range from about 55 mph at 300 m to 80 mph at 900 m. Roughly 12.2 mm is forecast overnight, with rain liable to affect both pitching and packing up. Pitches near 600 and 900 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. Condensation risk is high near 900 m. Ventilation will matter. The coldest temperature falls from about 7.9°C at 300 m to 5°C at 900 m.

Warmth planning: As a broad starting point, consider a 3-season bag with an ISO/EN comfort rating at or below about 4°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.

Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look very poor (0/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Psammite and semipelite (Morar Group). Dry quartz-rich bands can be grippy, while mica-rich or foliated sections, lichen and vegetation may become slippery when wet. Representative samples along available mapped routes also include Psammite, Pelite, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 75 mph. Crosswinds can make exposed ridges substantially more serious.
