Below is a graph of Historical Sea Surface Temperature for Flagler. This has been derived from analysis of two decades of oceanographic satellite measurements of nearby open water. We have calculated the average water temperature variation around the year as well as the extremes that have been observed on each date.
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.
Flagler sea temperatures peak in the range 28 to 30°C (82 to 86°F) on around the 24th of July and are at their lowest on about the 10th of February, in the range 18 to 22°C (64 to 72°F). Year round warm sea temperatures at Flagler climb to their warmest in the fourth week of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. Flagler sea temperatures are lowest in early to mid February. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up.
Actual sea surface water temperatures close to shore at Flagler 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 Flagler.
