Below is a graph of Historical Sea Surface Temperature for Guillotines. 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.

Guillotines sea temperatures peak in the range 21 to 24°C (70 to 75°F) on around the 5th of February and are at their lowest on about the 21st of August, in the range 15 to 18°C (59 to 64°F). Guillotines sea temperatures are always warm reach their maximum at the beginning of February. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The lowest seasonal sea temperatures at Guillotines in mid to late August lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots.

Actual sea surface water temperatures close to shore at Guillotines 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 Guillotines.
