Today's Surf Conditions at Belharra
Best Surf Season & Climatology
Best Surf Season (October - March)
Belharra is a spot built by the North Atlantic. From October through March, the storm track is aimed like a cannon at the Bay of Biscay, with deep extratropical lows rolling east-northeast and firing long-period NW and WNW groundswell into this exposed NNW-facing reef. Average wave heights sit between 5-7ft (1.6-2.1m) on the buoy, with periods in the 11-13s range, and the climatological frequency of offshore S/SSW winds jumps to 35-39%. This is the window when Belharra's unique bathymetry lights up: long, heavy, powerful waves with clean, groomed faces. December, January, and February are the crown jewels, with November and March close behind. When the NAO drops and the jet stream buckles over the eastern Atlantic, these months can produce multiple XL swells in a single week.
