Coffee Bay - surf spot statistics

Best Surf Season (May - August)

As the Southern Hemisphere winter takes hold, the breathing of the planet shifts and the Indian Ocean begins to pulse with purpose. For Coffee Bay, this is prime time. The combination of long-period groundswells from the deep Southern Ocean and the increased frequency of offshore westerly winds creates the most consistent and high-quality surf of the year. Average wave heights sit in the 2.0-2.3m range, with periods stretching beyond 11 seconds — that's powerful, long-period energy that wraps beautifully around the headlands. The wind is ideal a solid 31-46% of the time, with clean westerly and northwesterly flows grooming the lines. This is when Coffee Bay earns its reputation as a world-class wave. Expect pumping, heavy sets and plenty of rippable walls.

Fair Surf Season (April & September)

The shoulder months bring a mix of everything. In April, the swell is still robust at 2.1m average and periods are long (10.7s), but the wind starts to swing more onshore from the northeast. Ideal wind sits at 26%, which means you need to pick your windows. September sees the transition back to spring: swell holds at 2.2m and periods remain decent at 10.6s, but the offshore breeze consistency drops to 22%. During these months, the magic often comes in short but sweet bursts when a high-pressure system stalls over the interior, delivering glassy mornings and groomed, punchy surf.

Low Surf Season (October - March)

Summer brings the heat, and with it, the trade winds dominate. From October through March, the prevailing wind is from the northeast and east — directly onshore at Coffee Bay, ruining the wave quality. Average wave heights are still around 1.9-2.2m, but the periods shorten to 9.6-10.3s, producing more average, punchy and often choppy conditions. Ideal wind plummets to just 13-18%. The swell direction remains favorable (E through SSE), but the constant onshore flow makes it a struggle. That said, if a strong cold front pushes through and swings the wind to the west, you can score some fun to good waves before the trade winds reestablish. For the most part, though, it's a grovel or a waiting game.

June: Peak Winter, Peak Performance

June is the pinnacle. Average swell height holds at 2.1m, and the period reaches its annual maximum of 11.7s — very powerful, long period. Swell direction is heavily weighted from the S (18.5%) and SSW (22.4%), with a notable absence of north to east swell. This is pure Southern Ocean groundswell. The wind data shows a beautiful balance: NE winds drop to 12.4%, and offshore directions — NW (9.7%), WNW (6.7%), W (6.4%), NNW (7.6%) — account for a massive 46% ideal wind conditions. This is the highest of the year. When a strong cold front passes, expect the classic Coffee Bay set-up: a fresh west to northwest wind grooming lines of swell that wrap around the point. Wave heights frequently hit the 2-2.5m mark, with sets reaching XL on days of extra-strong storms. For the experienced surfer, June is the month to be here.
