Below is a graph of Historical Sea Surface Temperature for Lena. 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.

Lena 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.

Lena sea water temperatures peak in the range 27 to 30°C (81 to 86°F) on around the 6th of August and are at their lowest on about the 1st of March, in the range 17 to 19°C (63 to 66°F). Year round warm sea water temperatures at Lena climb to their highest in the first week of August. Even then a rash vest and board shorts should be fine for surfing at any time of year. The lowest Lena sea water temperatures at the beginning of March require something like a 3/2mm fully sealed wetsuit.

Actual sea surface water temperatures close to shore at Lena 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 Lena.
