Sunny with very warm air temperatures. In contrast the sea remains relatively cold (13 °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 No Pass. 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.

No Pass Water Temperature Graph

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.

No Pass sea water temperatures peak in the range 12 to 18°C (54 to 64°F) on around the 1st of September and are at their lowest on about the 14th of February, in the range 10 to 13°C (50 to 55°F). The highest sea water temperatures at No Pass at the beginning of September are ideally suited to a 4/3mm wetsuit + 3mm boots, although a 5/3mm wetsuit may be preferable for longer sessions and cold windy days. At its lowest in mid February, low sea water temperatures at No Pass are suited to a 5/4mm or 5/3mm good quality wetsuit with neoprene gloves and 3mm boots. You will need a hood if it's windy or the air is cold.

Actual sea surface water temperatures close to shore at No Pass 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 No Pass. Refer to our detailed weather forecasts for this information.

 

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
