How SwimScore works
One number. Four verdicts.
SwimPass pulls the latest forecast for your spot and weighs it for the kind of water it is. A sheltered lake and an exposed ocean beach don’t read the same.
- Waves & swell
- Wind & gusts
- Air temperature
- Rain & visibility
- UV
- Air quality
- Tide
Scored for you, free. Tell SwimPass how much wave, wind, cold and sun you’re happy with, and every spot is re-read for the way you swim.
