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.
Suits Advanced divers and up, as a dive guide states it. Scored for Advanced 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.

About Japanese Submarine I-1
A wreck dive in fresh water: a lake, quarry or spring. It goes down to 30 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces NE: swell from the NE reaches it, and wind from the SW blows out to sea. No dive centre within 50 km on the map: book a liveaboard or a boat from further off. The town to stay in is Honiara. Within 5 km we also list 4 dive sites.
