Where the data comes from
The weather data comes from Open-Meteo, an open weather service that combines forecast models from national weather services. For the featured mountains the app uses summit height so the temperature matches the altitude. For searched places, Open-Meteo uses the elevation of the place it finds.
The forecast is a model calculation. Thunderstorms and wind in the mountains are local and can only be forecast with limited precision.
How the assessment works
The assessment is our rule of thumb based on the daily values. Thunderstorms or gusts over 80 km/h trigger the warning level. More than 10 mm of precipitation, wind above 50 km/h or temperatures below minus 15 degrees mean: only with experience and the right kit.
A chance of rain above 50 per cent, wind above 30 km/h, frost or more than 30 degrees lead to “Fine to go out, keep an eye on conditions”. From UV index 6, a sun protection note is added.
How to read the result
The daily view shows high and low, chance of rain, wind and the assessment for each day. The hourly view shows when a shower is due, so you can time your start.
Times are local time at the chosen place.
Frequently asked questions
Does the app replace the mountain forecast?
No. Before any tour, read the regional mountain forecast and current warnings from the national weather service. The app gives you a quick overview.
Why is it colder than in the valley?
It gets colder as you climb, by about 0.65 degrees per 100 metres on average. That is why the app uses summit height for mountains.
What does chance of rain mean?
The likelihood of rain on that day or in that hour. It says nothing about how much will fall.
