Kate's seasonal overview

Best Surf Season (June - September)

The southwest monsoon unleashes its fury across the Indian Ocean, generating consistent south-southwest groundswell that marches right into this east-southeast facing reef pass. Average wave heights hover in the 1.2-1.3m range with periods steadily climbing into the 9-second zone – that's punchy, rippable juice. Meanwhile, persistent westerly winds (W, WNW, NW) blow offshore, grooming the face into clean walls. These months deliver the highest reliability of the year, with frequent sessions in the fun-to-solid category.

Fair Surf Season (May and October)

Shoulder months of the monsoon see a transition in both swell and wind. Swell from the south-southwest is still present but often mixed with less favorable directions, and wave heights average around 1.1m. Wind becomes more variable, but a solid chunk of time still offers offshore westerlies. Conditions can be excellent when a good swell lines up, but consistency drops – so pick your days wisely.

Low Surf Season (November - April)

The northeast monsoon dominates, bringing onshore winds from the east and northeast that chop up the surface. Swell is predominantly short-period (7-8s) and small (0.8-1.0m) from the east-northeast, which both opposes the optimal swell direction and blows directly onshore. While the occasional west swell or light wind window can salvage a session, the overall quality is poor. Most days you’ll be fighting bumpy, low-energy conditions.

Conditions at Kate's in December

December: Northeast Monsoon Takes Over

December plunges back into the low season. Winds shift hard to the east, with NE (20%) and ENE (26%) dominating – that means onshore wind the majority of the time. Ideal wind plummets to 28%. Swell is predominantly from the ENE (31%) and E (27%) – short-period (7.5s), averaging 1.0m, and blowing directly against the optimal west swell direction. Surf quality suffers from bumpy, weak conditions. The rare strong west swell can still light up the reef, but those are few and far between. Expect mostly small, choppy, and shelved waves until the next monsoon shift.
