What is the current weather on Snowdon summit?
The live forecast above shows the latest wind, temperature and visibility readings for the summit. Conditions can shift in minutes, so always check before you set off.
- Wind speeds at the top are often double those at the base – gusts over 50 mph are common even when the valley is calm.
- Temperature drops roughly 1°C every 200 metres of ascent; the summit (1,085 m) is frequently below 5°C in summer and well below freezing in winter.
- Visibility can fall to less than 20 metres when cloud sits on the peak – the Snowdon summit weather cam (available via the Met Office) gives a live view.
- Check the weather in Snowdonia 10 days ahead if you’re planning a trip, and use the Snowdon summit weather 14 days outlook for longer-term trends.
How does the summit weather compare to the lower slopes?
Conditions at the summit are far more severe than in the valleys, and the difference can catch walkers off guard. The Snowdonia weather forecast 21 days and Snowdonia weather 30 days can help with advance planning, but always rely on the live forecast above for the day.
- Rainfall on the summit is roughly double that at Llanberis – expect wet ground even on dry-looking mornings.
- Snow can linger on the summit into May and return as early as October; check the Snowdon summit weather tomorrow before deciding on footwear and layers.
- Thunderstorms develop quickly on the mountain – if you hear thunder or see lightning, descend immediately.
Is it safe to climb Snowdon today?
Use the live forecast above and check mountain weather warnings from the Met Office. Avoid the summit if winds exceed 40 mph, visibility is below 100 m, or thunderstorms are forecast. Always carry a map, compass and extra layers.
Where can I see a Snowdon summit weather cam?
The Met Office operates a webcam at the summit café. It updates every 15 minutes and gives a real-time view of cloud cover, rain and snow. Link it with the live forecast above to make a safe decision before heading up.
What is the Snowdon summit weather 14 days outlook?
Long-range mountain forecasts are less reliable than short-term ones. Use the 14-day view for general trends (e.g. persistent low pressure) but always check the live forecast above and the weather in Snowdonia 10 days page for a firmer picture.
