Renaca sea water temperatures peak in the range 16 to 19°C (61 to 66°F) on around the 18th of February and are at their minimum on about the 14th of August, in the range 12 to 14°C (54 to 57°F). The highest seasonal sea water temperatures at Renaca in the third week of February lend themselves to a 4/3mm wetsuit or a 3/2mm suit and 3mm neoprene boots. The minimum sea water temperatures at Renaca in mid 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 Renaca 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 Renaca.
