The day on the hill

Strong gusts and frequent summit cloud on Càrn nan Gobhar (Strathfarrar): summit wind broadly 25-40 mph, with gusts 45-55 mph at times (strong winds).

Wind & exposure

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Gusts may knock you off balance on exposed ground, even between spells of lighter wind.

Cloud & views

Cloud base around 500–800 m through the morning, lifting to 800–1100 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 western slopes and lift somewhat on the eastern side, but local terrain can differ. Any sunshine may be confined to lower ground or breaks away from the summit.

Drizzle is forecast at times. The forecast total is up to around 2 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 differ on summit wind strength: around 33-37 mph at walker height, with gusts 46-52 mph.

Rain & temperature

The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives.

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 30% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 1.6 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. A little rain may coincide with pitching or packing up. Pitches near 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 300, 600 and 900 m. Ventilation will matter. The coldest temperature falls from about 6.3°C at 300 m to 4.6°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.

The ground is likely to be very wet after recent rain. Expect boggy approaches and choose a durable pitch carefully.

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 (Glenfinnan 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 Gneissose pelite and gneissose semipelite, Semipelite and psammite, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 50 mph. Crosswinds can make exposed ridges substantially more serious. Cloud may also make route-finding and retreat harder.

The day on the hill

Frequent summit cloud on Càrn nan Gobhar (Strathfarrar): summit wind broadly 25-35 mph, with gusts 40-50 mph at times (strong winds). Hill cloud may make navigation difficult, with very poor visibility in wetter spells.

Wind & exposure

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

Cloud & views

Cloud base mostly around 600–900 m through daylight. 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. Very little direct sunshine is likely, with extensive cloud.

Drizzle is forecast for much of the day. The forecast total is up to around 2 mm, but local amounts will vary.

Forecast models differ on summit wind strength: around 23-38 mph at walker height, with gusts 32-53 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. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops. 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 23-38 mph, which changes how difficult exposed walking may feel.

The day on the hill

On Càrn nan Gobhar (Strathfarrar): summit wind broadly 5-20 mph, with gusts 20-30 mph at times (a moderate breeze).

Cloud & views

Cloud base around 3000–3300 m in the morning, then around 800–1100 m around midday and 1400–1700 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening.

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

Sunny spells are possible away from summit cloud, but may not reach the top while it is in cloud. Drizzle is forecast at times.

The forecast total is up to around 2 mm, but local amounts will vary. Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around -2 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: Cloudier around midday at about 25%, compared with around 90% early and 90% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 6.2 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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look mixed (45/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Psammite and semipelite (Glenfinnan 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 Gneissose pelite and gneissose semipelite, Semipelite and psammite, so rock character and wet-weather behaviour may change across the mountain.

Cloud & views

Cloud base around 1200–1500 m in the morning, then around 1400–1700 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 early morning into around midday.

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. Very little direct sunshine is likely, with extensive cloud.

Drizzle is forecast at times. The forecast total is around 2-5 mm, but local amounts will vary.

Cold on exposed tops: air temperature broadly 0 to 4°C, feeling around -6 to -2°C in the wind.

The day on the hill

Strong gusts and frequent summit cloud on Càrn nan Gobhar (Strathfarrar): summit wind broadly 25-40 mph, with gusts 40-50 mph at times (strong winds).

Wind & exposure

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Gusts may knock you off balance on exposed ground, even between spells of lighter wind.

Cloud & views

Cloud base around 700–1000 m in the morning, lifting to 900–1200 m around midday. Cloud is likely to cover the top for much of the day, though a brief clearance is possible from late morning into midday.

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.

Rain & temperature

Little or no rain is forecast. Cold on exposed tops: air temperature broadly 4 to 8°C, feeling around -4 to 0°C in the wind.

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

Forecast confidence

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

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

Cloud-free timing: Around 25% early, improving to around 35% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 11 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.

Morning · 08:00–12:00 Poor Summit winds around 20-35 mph. Gusts around 40-50 mph are possible on exposed ground. Buffeting may affect balance on exposed ground, particularly near ridges and edges. Summit cloud is more persistent early in this period, with better prospects later.

Exposed camping is not recommended near 300, 600 and 900 m: gusts may reach about 70 mph. Sustained winds may reach about 50 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 50 mph at 300 m to 70 mph at 900 m. Roughly 12 mm is forecast overnight, including rain around pack-up. Pitches near 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 6.7°C at 300 m to 5.2°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 poor (30/100). Rock is likely to be mostly dry, though seepage and shaded holds are not resolved. The mapped summit rock is Psammite and semipelite (Glenfinnan 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 Gneissose pelite and gneissose semipelite, Semipelite and psammite, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 45 mph. Crosswinds can make exposed ridges substantially more serious. Cloud may also make route-finding and retreat harder.
