Matanzas Inlet Water Temperature and Wetsuit Guide

Sunny with very warm air temperatures, feeling like 26 °C once we account for air movement. In contrast the sea remains relatively cold (19 °C). Surfers should wear a spring or summer wetsuit though no doubt some would wear less neoprene on such a warm day, no matter what temperature the sea is.

Below is a graph of Historical Sea Surface Temperature for Matanzas Inlet. 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.

Matanzas Inlet sea temperatures peak in the range 28 to 30°C (82 to 86°F) on around the 26th of July and are at their minimum on about the 11th of February, in the range 18 to 22°C (64 to 72°F). Year round warm sea temperatures at Matanzas Inlet climb to their highest in the fourth week of July. Even then a rash vest and board shorts should be fine for surfing at any time of year. Matanzas Inlet sea temperatures are minimum in the second week of 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 Matanzas Inlet 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 Matanzas Inlet.
