Route Weather & Viability Forecast

How the route viability forecast works

Upload a GPX for any trail or route and the tool finds its high point, fetches a 7-day forecast there, and rates each day for running or hiking. The rating blends the things that actually decide whether an outing is sensible: temperature (too hot on an exposed climb, or a hard overnight freeze), rain, fresh snow up high, and wind. The best window for the week is highlighted so you can pick your day.

• "Is it snow-free yet?" checks for spring and early-summer alpine routes.
• Picking the best day this week for a long run or hike.
• Sanity-checking a route before committing — then diving into the detailed snow forecast if it looks marginal.

Frequently asked questions

Is this route good to run or hike this week?

Upload a GPX and this tool checks a 7-day forecast at the route’s high point, then rates each day for running or hiking based on temperature, rain, fresh snow, and wind — and highlights the best window.

Why does it use the high point of the route?

Conditions up high decide whether a route is sensible — that is where it stays snowy, cold, or windy longest. Judging by the high point avoids a valley forecast hiding a snowed-in col.

How reliable is the forecast?

It is a planning aid, not a guarantee. Forecasts get less certain further out, mountain weather changes fast, and local effects matter. Always check official conditions before committing.

Where does the weather data come from?

Open-Meteo, a free weather API. Your GPX is parsed in your browser; only a single representative coordinate is sent to fetch the forecast.
