A hot sunny day, feeling like 30 °C even after we account for wind, and warm water temperature (23 °C) too at Ilha Porchat. Surfers may need a thin summer wetsuit or at least a rash vest to block the UV. Otherwise, warm enough for just board shorts.

Below is a graph of Historical Sea Surface Temperature for Ilha Porchat. 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.

Ilha Porchat sea water temperatures peak in the range 24 to 28°C (75 to 82°F) on around the 26th of February and are at their lowest on about the 12th of August, in the range 17 to 21°C (63 to 70°F). Year round warm sea water temperatures at Ilha Porchat climb to their highest in the fourth week of February. Even then a rash vest and board shorts should be fine for surfing at any time of year. The lowest Ilha Porchat sea water temperatures in the second week of August require something like a 3/2mm fully sealed wetsuit.

Actual sea surface water temperatures close to shore at Ilha Porchat 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 Ilha Porchat.
