Sultans - surf spot statistics

Best Surf Season (June - October)

When the Indian Ocean’s southwest monsoon kicks into gear, Sultans transforms into a consistent, punchy left-hander. The trade winds shift, sending powerful long-period swell from the West and Southwest straight into the reef. Average heights hover in the 1.2m range with periods regularly exceeding 8 seconds, and the offshore flow from the northwest quadrant keeps the wave faces clean and lined up. This is prime time – expect fun-sized to pumping sets, with the occasional pulse from distant southern ocean storms pushing into the 1.5-2.5m ‘firing’ range. The reliable afternoon seabreezes are minimal, and you’ll find the best conditions from early morning to midday, when the offshore winds are most consistent.

Fair Surf Season (April - May & November)

These transitional months see a blending of swell windows. April offers excellent offshore wind statistics (64% ideal) but the swell tends to be smaller and more southerly, often wrapping in with less power. May and November bring a mix - you’ll get pulses of solid WSW and W swell, but the wind can be fickle, swinging onshore for days at a time. When the synoptic setup aligns – a strong low south of Madagascar and a high-pressure ridge over the Bay of Bengal – you can score clean, 1-1.5m rippable waves. But it’s a gamble, and you’ll need patience to pick the right days.

Low Surf Season (December - March)

The northeast monsoon dominates from December through March, driving steady ENE and E trades that unfortunately blow directly onshore at Sultans. Swell comes mainly from the east, wrapping in short-period, choppy lines (<6s) that rarely exceed 1m. The reef struggles to organize these weak, bumpy waves, and the constant onshore wind makes conditions messy. Occasional pulses from the north can sneak in with a better period, but the overall consistency is poor. If you are not desperate for a splash, save your trip for the southwest monsoon months.

December: Winter Onslaught

December welcomes back the northeast monsoon with a vengeance. ENE wind dominates (27.5% of total), blowing onshore at 10-35kph. Swell from ENE (41.4%) and E (23%) builds to an average 1.0m but with a short, weak period of 6.9s. Ideal wind only 30% of the time. The result is a month full of choppy, low-energy waves that struggle to break cleanly on the reef. On the rare occasion a NW cold front pushes through, you might get a brief window of smaller, cleaner surf, but don’t plan a trip around December. Save your holiday for the summer months.
