Tides

Tides run on a cycle of approximately 6-7 hours. That is, it's 6-7 hours between the highest point of a high tide and the lowest point of the next low tide.

There are usually two high tides and two low tides each day. Most of the time one high and low is more extreme than the other.

The extreme lowest tides of the year occur in summer, generally in mid-afternoon, and in winter mostly during the middle of the night.

Weather conditions such as high winds can cause high tides to be higher than predicted.
