Adonis - surf spot statistics

Best Surf Season (March - April & November)

The transition months between the northeast and southwest monsoons deliver the most consistent quality at Adonis. During March and April, the weakening NE trades give way to a more variable wind regime, with offshore flows from the NW quadrant becoming frequent. Swell directions shift firmly into the S-SSW-SW window, firing the reef with clean, long-period groundswell. November sees a similar setup as the SW monsoon retreats, bringing a high percentage of offshore NW winds and powerful SSW-SW swell. These months offer the best balance of groomed faces and punchy wave heights.

Fair Surf Season (February, May, September, October, December)

February and December still see a mix of NE and E wind patterns but benefit from occasional NW offshore breaks and solid S-SSW swell. September and October sit in the heart of the SW monsoon; while swell is plentiful from the south, the prevailing W to WSW onshore flow often chops up the surface. May is a similar story – the SW monsoon is becoming established, bringing decent size but ruining quality with onshore winds a majority of the time. These months require patience to pick the right window.

Low Surf Season (January, June, July, August)

January is locked into the northeast monsoon with dominant NE winds and swell from the E-ENE quadrant – both poor for Adonis. The small, short-period E swell barely reaches the reef, and the NE winds create bumpy, unrideable conditions. During June, July, and August, the southwest monsoon peaks, delivering plenty of S-SSW swell but almost constant onshore W to WSW winds. The wave heights can be fun-sized but the texture is often messy, making it hard to find a clean wall. These months are best left to the brave or the boat-chasing crew.

April: Peak Offshore Synergy

April reaches the highest ideal wind frequency at 60%, thanks to a strong shift toward the NW quadrant. Offshore winds from W (22.2%), WNW (17.8%), NW (8.6%), and NNW (4.1%) total over 50% onshore? Wait, careful. W wind is actually onshore (since spot faces SE, W is cross-shore? Actually wind from W is cross-shore to offshore? The spot exposure is SE. Wind from W is blowing from west to east, which is cross-shore from the left? Actually, if the beach faces SE, then a west wind blows from the west, which is from the left side of the beach? More precisely, onshore wind is from the sea, i.e., from directions that blow onto the beach. Since beach faces SE, onshore winds are from SE, SSE, S, SSW, SW, WSW? Actually, the spot's onshore wind directions are OSO (WSW), SO (SW), SSO (SSW), S. So wind from W is actually not listed as onshore – it might be cross-shore or slightly offshore. The rule says optimal wind from N, WNW, NW, NNW. So W is not ideal but also not explicitly onshore. Given that, I'll treat W as neutral. But the data shows W at 22.2% – not ideal but not fully onshore. The key offshore are WNW, NW, NNW, N. Those total 17.8+8.6+4.1+2.5 = 33% – still significant. Swell is pure southern: 28.2% S, 40.1% SSW, 17% SW – all perfect for Adonis. Average period is 12.0s, wave height 1.0m – clean, long-period lines. This month offers the most consistent combination of offshore winds and quality swell.
