Below is a graph of Historical Sea Surface Temperature for Blacks Reef. 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.

Blacks Reef 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.

Blacks Reef sea water temperatures peak in the range 18 to 21°C (64 to 70°F) on around the 9th of February and are at their minimum on about the 24th of August, in the range 13 to 14°C (55 to 57°F). The warmest Blacks Reef sea water temperatures in early to mid February require something like a 3/2mm fully sealed wetsuit. The minimum sea water temperatures at Blacks Reef in the fourth week of August 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.

Actual sea surface water temperatures close to shore at Blacks Reef 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 Blacks Reef. 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.
