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 The Bottleneck Milne Bay
A drift dive. It goes down to 30 m. You get in from a boat. It suits experienced divers only, as a dive guide states it. The coast faces SE: swell from the SE reaches it, and wind from the NW blows out to sea. No dive centre within 50 km on the map: book a liveaboard or a boat from further off. The sea is about 26°C in July, its coldest month (3 mm wetsuit), and 30°C in March, its warmest (rash vest or 1 to 2 mm). The town to stay in is Samarai. Within 5 km we also list 1 dive site.
