The day on the hill

On Mynydd Drws-y-coed: summit wind broadly 15-30 mph, with gusts 35-45 mph at times (strong winds). Hill cloud may make navigation difficult, with very poor visibility in wetter spells.

Things to watch

Severe spate risk from the morning into the afternoon, with forecast rain and subsequent runoff. 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.

Cloud & views

Cloud base around 600–900 m in the morning, lifting to 800–1100 m around midday and 1600–1900 m by late afternoon. 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

Rain is likely to include a heavy spell, with around 10-20 mm expected over the assessed day. Forecast models differ on summit wind strength: around 25-31 mph at walker height, with gusts 35-43 mph.

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.

Rain is forecast during the morning, but models differ considerably on the amount.

Cloud-free timing: Around 40% early, improving to around 95% later.

Sunshine context Model-grid estimate, not summit sunshine

The surrounding model grid indicates 4.8 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 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 Siltstone (Nant Ffrancon Subgroup). Often positive when dry, but smooth, polished or slabby sections can become markedly more slippery when damp. Gusts may reach about 40 mph. Crosswinds can make exposed ridges substantially more serious.

The day on the hill

Strong gusts on Mynydd Drws-y-coed: summit wind broadly 20-35 mph, with gusts 40-50 mph at times (strong winds).

Wind & exposure

Much calmer lower down - generally 15-25 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 1300–1600 m in the morning, lowering to 1400–1700 m around midday and 500–800 m by late afternoon. Cloud is likely to come and go across the top, with views in the clearer spells.

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.

Rain & temperature

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

Little or no rain is forecast. Forecast models differ on summit wind strength: around 29-35 mph at walker height, with gusts 41-49 mph.

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

The day on the hill

Strong gusts and frequent summit cloud on Mynydd Drws-y-coed: summit wind broadly 25-45 mph, with gusts 50-60 mph at times (strong winds). Visibility may drop briefly in showers.

Things to watch

Possible spate risk through much of the day and into the evening, with recent and forecast rain and subsequent runoff. 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. Gusts may knock you off balance on exposed ground, even between spells of lighter wind.

Cloud & views

Cloud base mostly around 500–800 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. Any sunshine may be confined to lower ground or breaks away from the summit.

Rain & temperature

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

Forecast models differ on summit wind strength: around 27-47 mph at walker height, with gusts 37-65 mph.

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. Forecast models differ on whether meaningful rain reaches the hills during the afternoon and evening.

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

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.

Open-hillside camping looks promising overall around 600 m (82/100). It may be breezy on open ground, with gusts near 25 mph. Little overnight rain is forecast. Pitches near 600 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. Forecast models are not closely enough agreed for an exceptional grade.

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 Siltstone (Nant Ffrancon Subgroup). Often positive when dry, but smooth, polished or slabby sections can become markedly more slippery when damp. Gusts may reach about 55 mph. Crosswinds can make exposed ridges substantially more serious. Cloud may also make route-finding and retreat harder.

The day on the hill

Strong gusts on Mynydd Drws-y-coed: summit wind broadly 30-45 mph, with gusts 55-65 mph at times (gale-force mean winds at times). Heavier showers may bring brief, stronger gusts and rapidly reduced visibility.

Things to watch

High spate risk from the morning into the afternoon, with forecast rain and subsequent runoff. 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 15-25 mph in the valley, rising towards the tops.

Cloud & views

Cloud base around 1300–1600 m in the morning, then around 600–900 m around midday and 1300–1600 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the morning.

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.
