Full forecast
every day, every number
The score doesn't know currents, the visibility on the day or your certification.
Fresh water: lake, river or quarry: scored by other rules.
Fresh water has no waves to forecast, so the 39 points out of 100 that a sea site gets for a calm sea are given in full. The day turns on the wind (20 points) and the rain (6); gusts of 30 kn or more still score it nothing.
No satellite reads a lake's clarity or its water, so its day is its surface alone: 65 of 100, where a sea site also scores up to 20 for how far you see and 10 for warm water (D275).
No sea temperature is read for it: nothing forecasts a lake's water, and it is often much colder at depth than at the top. Ask a dive centre what suit to bring.
