Snowdon summit weather is changeable and often severe. The live forecast above shows the immediate outlook, but conditions can flip from calm to gale-force in minutes, with cloud, rain or snow possible even in summer.
What is the weather like on Snowdon summit today?
The live forecast above gives the best guide for the day ahead. Summit temperatures typically run 10–15°C cooler than at the base, so expect wind chill and sudden visibility drops. For a wider picture, check the 10 day weather forecast UK for Snowdonia, but always treat mountain forecasts as approximate—conditions can shift quickly above 1,000 metres.
Is it safe to climb Snowdon today?
Safety depends on the live forecast above and your experience. Even in fair weather, summit winds can reach 40–50 mph, and cloud can reduce visibility to zero. Use the Met Office Mountain Forecast alongside the live data. Avoid summiting if the forecast shows persistent cloud, rain or winds above 30 mph unless you are properly equipped with map, compass, warm layers and waterproofs. The UK weather hub has more regional guidance.
