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 South Neptune Pinnacles
A pinnacle dive. It goes down to 20 m. You get in from a boat. It suits experienced divers only, as a dive guide states it. The coast faces S: swell from the S reaches it, and wind from the N 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 15°C in August, its coldest month (7 mm semi-dry or a drysuit), and 19°C in January, its warmest (7 mm wetsuit and hood). No town nearby. Tulka, 68 km away, is the nearest town we list; we have not checked places to stay there. Nearest beds: Marion Bay, 79 km. Nearest airport: Port Lincoln Airport (PLO), 85 km. Within 5 km we also list 2 dive sites.

What you might see
Too few open records near this site to list its animals. Ask a dive centre what you are likely to see.
This week: visibility about 25 m, about usual for the month (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.
The current and the life no free forecast gives. Ask a dive centre before you book.
