WindTrac: Wind & Wave Map

WindTrac is a weather app that turns raw data into a living, animated map you can read at a glance. Tens of thousands of particles stream along the wind field — speed as colour, direction as motion — for a clear, beautiful picture of the moving air anywhere on Earth, from your coast to the open ocean.

WindTrac is built for sailors, kitesurfers, windsurfers, surfers, paraglider pilots, fishermen, boaters, hikers, photographers, and anyone who plans a day around the weather.

**Five weather layers, animated**

Wind streams as glowing particles across the whole globe. Waves show significant wave height as a colour heatmap with wave direction and period. Precipitation paints rain and snow intensity frame by frame so you can watch systems come and go. Cloud cover shows the low cloud that actually blocks the sun. Temperature gives 2 m air temperature in °C or °F.

**Wind at every altitude**

Read the wind from 10 m at the surface up through the 850, 700, 500 and 250 hPa pressure levels — the whole column from a paraglider launch to the jet stream, on one slider.

**Time you can scrub**

Every layer is time-animated. Drag the timeline to any forecast hour or press play, with smooth transitions and speeds from 1× to 8×, and watch a multi-day weather system unfold in seconds.

Tap anywhere on the map to read the exact wind speed, wave height or temperature — the notable highs and lows are labelled automatically. Save favourite spots and jump straight to them. Show times in your device zone, the viewed location's zone, or UTC.

**Multiple professional forecast models**

WindTrac is built on public data from the world's leading weather centres, and lets you pick the model per layer: NOAA GFS (global), NOAA GEFS ensemble mean, DWD ICON and ICON-EU (highest resolution), ECMWF AIFS (AI global model), ECMWF IFS HRES (the reference physical model), plus the GFS and ECMWF wave models.

**Works fully offline**

With WindTrac Pro, download a region and its complete forecast — every layer and the basemap — for offline use. The animation, layers and timeline keep working out at sea, in the backcountry, on a plane, or anywhere mobile coverage ends.

**Simple, free and private**

The full interactive map, every layer, every model, timeline playback, saved locations and 72 hours of forecast are free — no ads, no account. WindTrac Pro is an optional subscription f
