Day scores are the conditions out of 80, from the two best daylight readings: a morning and an afternoon dive. Sea is the open water's waves near the site, in metres, halved for a sheltered site. Wind and gusts are in knots (10 kn is about 19 km/h); "boats in" marks gusts that keep dive boats in. This week's visibility, the current and the life no free forecast gives.
