Westbrook - surf spot statistics

Best Surf Season (May - August)

The Southern Hemisphere winter fires up the Indian Ocean, and Westbrook reaps the rewards. From May through August, the average swell period climbs above 10 seconds, peaking at 10.8s in June, signalling long-period groundswells that wrap beautifully into the East-Southeast-facing beach. Simultaneously, the frequency of offshore winds from the west through north-northwest increases dramatically, with ideal wind conditions occurring 48-55% of the time. Extratropical storms along the Antarctic Polar Front generate consistent, powerful swell trains, while the South Atlantic high-pressure system strengthens, funnelling clean westerly breezes across the coast. This is the window for pumping, firing surf at Westbrook.

Fair Surf Season (March - April & September)

Shoulder months offer a blend of quality and quantity. March and April see solid swell heights (average 1.7m) and periods around 10s, with offshore wind percentages climbing from 25% to 35%. The swell direction remains dominantly from the east through south-southeast, hitting the optimal window. September still holds onto winter swell momentum, but the wind becomes less reliable as the season transitions. You'll find fun, rippable conditions, but you'll need to pick your windows carefully as onshore easterlies become more frequent.

Low Surf Season (October - February)

The summer months bring a stark contrast. From October to February, the average swell height holds at 1.6-1.8m, but the period drops to 8.7-9.4s, reflecting shorter-period, less powerful windswell. More importantly, offshore winds are scarce, occurring only 14-18% of the time. The predominant winds shift to the northeast through east-southeast—directly onshore—wrecking wave shape and creating choppy, messy conditions. The Indian Ocean high-pressure belt weakens, and thermal lows over the interior pull in humid, easterly flow. While a rogue long-period groundswell can still sneak through, the odds are stacked against clean, offshore surf. It's a time for groveling or waiting for the autumn transition.

April: Golden Shoulder Season

April sees a significant uptick in surf quality. Ideal offshore wind frequency jumps to 35%, with westerly and north-westerly flows becoming more reliable. Winds from the southwest through north now combine for a respectable slice of the wind rose. The average swell height holds at 1.7m, but the period reaches 10.0s—solidly in the powerful range. Swell directions are well-balanced: east (17.9%), east-southeast (15.5%), southeast (17.5%), south-southeast (20.0%), and south (14.9%). This spread means Westbrook catches swells from a broad fetch of the Indian Ocean. The strengthening South Atlantic high-pressure system pulls more frequent westerly winds, allowing the beach to clean up. Expect pumping days where the swell lines up with offshore breezes—definitely the start of the prime window.
