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.

May: Southwest Swell Arrives

The southwest monsoon starts to flex, and the swell spectrum shifts dramatically. WSW swell dominates at 22.9%, with W and SW both over 15%. Average height climbs to 1.1m and period settles at 7.5s. Unfortunately, winds are less favorable than April – only 41% ideal – with strong WSW and W winds blowing onshore 32% and 35% of the time. This creates a love-hate scenario: when the wind is light or from the NW, you get clean, fun 1-1.5m sets; when the trades are up, it’s a choppy battle. May is the first month with real potential for quality sessions, but you’ll need to read the forecasts closely.
