Quick start

1
Open the GPX panel (second tab) and upload a .gpx file from your device. Your track appears on the map.
2
Open the Weather panel (first tab). Set your departure date and time.
3
Make sure Track is checked, then tap the update button. Weather is fetched for each point along the route based on your estimated arrival time at that point.
Tip: WeatherGPX estimates your arrival time at each point using the distance and the speed set in the Settings panel. Set your activity type and speed before fetching weather for best results.

Weather options

Track

Fetches weather for each sampled point along your GPX route. The forecast accounts for your estimated arrival time at each point, so you see the weather you'll actually encounter — not just the weather at departure.

Area

Fetches current weather for the area currently visible on the map, without needing a track. Useful for a quick overview of conditions in a region.


Departure time

The departure date and time determine when you start the route. WeatherGPX adds your estimated travel time to get the forecast at each point. A 10 km point at 20 km/h gets the forecast for 30 minutes after departure, and so on.

If your GPX file contains timestamps, those are used directly. Otherwise, speed and activity type from Settings are used.


Sample interval

WeatherGPX downsamples your track to one weather point every N km (default 1 km). A shorter interval gives more detail but uses more of your hourly fetch quota. For a 50 km route at 1 km intervals, that's 50 weather fetches — counted as one update.


Fetch limits

To keep the service free and fair, weather updates are rate-limited per hour:

The limit resets at the top of each hour.


Account & sync

Without an account, your tracks are saved in your browser only — they are lost if you clear browser data. With a free account, your tracks and settings are synced to the cloud and available on any device you sign in to.

You can sign in with Google or create an account with email and password. Google sign-in does not require a password.


Offline use

WeatherGPX works offline. The app, your tracks, and previously fetched weather are all available without an internet connection. Map tiles are cached as you view them — if you browsed the route area while online, the map will display correctly offline too.

Tip: Before heading into the field, open your track, fetch the weather, and pan around the route on the map. Everything you've viewed will be available offline.
