Below is a graph of Historical Sea Surface Temperature for Road K. 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.

Road K water temperatures peak in the range 21 to 24°C (70 to 75°F) on around the 2nd of August and are at their coldest on about the 1st of March, in the range 3 to 6°C (37 to 43°F). Road K water temperatures are always warm reach their maximum in early August. You'll need a 2mm neoprene top or a shorty at dawn/dusk or if it's windy. The coldest water temperatures at Road K mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here at the beginning of March.

Actual sea surface water temperatures close to shore at Road K 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 Road K.
