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 Tewksbury Rock
A reef dive. It goes down to 15 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it.

The sea is about 4°C in February, its coldest month (drysuit), and 19°C in July, its warmest (7 mm wetsuit and hood). For Advanced divers the best months are usually May, June, July and August, with about 7 good days in 7. From the weather of past years. The town to stay in is Hull.
