The forecast at that summit ridge, at the exact hour you'll stand there
A storm forecast at 13:00 is harmless if you summit at 10:00. WeatherGPX shows the weather at each waypoint at your actual arrival time, not a generic daily snapshot.
It's 22° at the trailhead, 8° at 2800m. WeatherGPX uses Open-Meteo's altitude-aware forecast model for realistic temperature at each waypoint along your ascent.
16-day forecast horizon, full route weather profile, best departure time finder. Plan your alpine traverse or long-distance trail a week ahead and choose the best weather window.
Active wildfires, floods, earthquakes, cyclones, volcanoes and droughts, drawn on the map from NASA FIRMS and GDACS. Check the massif from home, not from the trail on one bar of signal.
Works with GPX files from Komoot, Wikiloc, AllTrails, or any GPX-exporting app
Export your trail from Komoot, Wikiloc or AllTrails and upload it to WeatherGPX. Or paste a Google Maps walking route link.
Tell WeatherGPX your average hiking speed and when you plan to set off. It estimates your arrival at the col, the summit, and every point in between.
Temperature, wind, precipitation probability at every waypoint, at the exact hour you'll be there. Up to 16 days ahead, plan your summit day with confidence.
Free, no account needed, works on any trail anywhere in the world.
