Snowdon weather tomorrow

This page shows tomorrow's live forecast for the summit of Yr Wyddfa at 1,085 m from Open-Meteo: wind and gusts, feels-like temperature, rain, cloud and freezing level, with sunrise, sunset and the latest safe start for each path.

Usually very different. The summit is about a kilometre higher, so it is normally much colder and windier. The comparison above shows both for tomorrow.

Between sunrise and the latest safe start shown above for your path: tomorrow's sunset minus Eryri's time for the path, minus a 1 hour buffer. Slower walkers should start earlier still.

Look at the summit gusts, the feels-like temperature and the cloud for the hours you will be walking, not just the morning. If the warnings above show strong wind or the summit is in cloud all day, pick another day or a lower walk.

Use more than one. Alongside this forecast, check the Met Office mountain forecast for Snowdonia and MWIS, which are written for hill walkers.

The railway says services can be disrupted or stopped by weather, and high winds affect services all year. Check its website on the day. The last 2026 diesel service is on 1 November 2026.
