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

Bundoran sea water temperatures peak in the range 13 to 17°C (55 to 63°F) on around the 6th of August and are at their lowest on about the 21st of February, in the range 8 to 10°C (46 to 50°F). The warmest sea water temperatures at Bundoran in the first 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. The lowest sea water temperatures at Bundoran mean that you will need a flexible 6/5/4mm wetsuit or a well fitting 5/4mm wetsuit with gloves and 5mm neoprene booties and a hood to surf here in mid to late February.

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