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 34 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.
Suits experienced divers only, by its depth against the depths each course trains to. Scored for experienced divers.

Local clock times; heights about mean sea level. On open coasts the times are usually within a quarter of an hour; in bays, estuaries and on the Gulf of Mexico they can be an hour or more out. Slack water, the safest time to dive where there is current, is about half an hour either side of each high and low.
