The Patch Water Temperature Graph

All of the graphs for the surf breaks presented on Surf-Forecast.com are on the same scale to enable comparison between locations around the world.

The Patch sea water temperatures peak in the range 13 to 17°C (55 to 63°F) on around the 24th of September and are at their minimum on about the 6th of April, in the range 10 to 14°C (50 to 57°F). The highest sea water temperatures at The Patch in the fourth week of September are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days. At its minimum in the first week of April, low sea water temperatures at The Patch are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at The Patch can vary by several degrees compared with these open water averages. This is especially true after heavy rain, close to river mouths or after long periods of strong offshore winds. Offshore winds cause colder deep water to replace surface water that has been warmed by the sun. Air temperature, wind-chill and sunshine should also be considered before deciding on the kind of wetsuit needed to stay warm when surfing at The Patch.
