Sunny with very warm air temperatures. In contrast the sea remains relatively cold (16 °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.
(click thumbnails to expand) Below is a graph of Historical Sea Surface Temperature for Dias Beach. 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. Dias Beach water temperatures peak in the range 20 to 24°C (68 to 75°F) on around the 29th of January and are at their coldest on about the 5th of August, in the range 16 to 18°C (61 to 64°F). Dias Beach water temperatures are warmest in late January. Surfers should use a 2mm long sleeve shorty or a 3/2mm spring wetsuit if the wind is up. The coldest seasonal water temperatures at Dias Beach at the beginning of 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 Dias Beach 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 Dias Beach.
