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.

  1. 80–100

    Get in.

    Conditions line up. Go swim.

  2. 60–79

    Good swim.

    Worth the trip. Check the detail first.

  3. 40–59

    Your call.

    Something’s off — wind, waves or weather. Know your limits.

  4. 0–39

    Stay dry.

    Not today. Watch for the next window.

Fewer spots. Better water.
