Your Garmin becomes a speed logger on the water.

SpeedSurf shows your speed on your wrist while you ride: Max 2 sec, Max 10 sec, Avg LEG 10 sec and Alpha 500, plus 250 m, 500 m and the nautical mile. Windsurfing, windfoiling, wingfoiling, kitesurfing, kitefoiling, pump foiling or parawing.

When you save, the session goes to Garmin Connect like any activity. Make an API key on speedsurf.app under Settings and then Devices, paste it into the SpeedSurf settings in Garmin Connect, and the watch sends the track straight to speedsurf.app by itself, so your ride is on the site before you are off the beach. Leave the key empty and nothing leaves the watch.

Knots or km/h, your choice. Free, no account needed on the watch.
