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 Crystal Cave
A cave dive. It goes down to 20 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces W: swell from the W reaches it, and wind from the E blows out to sea. No dive centre within 10 km, the nearest 44 km away. The sea is about 16°C in August, its coldest month (7 mm wetsuit and hood), and 22°C in February, its warmest (5 mm wetsuit). The town to stay in is Tutukaka. Within 5 km we also list 15 dive sites.

This week: visibility about 20 m, clearer than usual (satellite plankton reading, 24 Oct). Estimated from the month's typical visibility and this week's satellite chlorophyll against the site's normal; heavy rain before a dive can still muddy it.
