Jelly's Point seasonal overview
Best Surf Season (November - February)
Jelly's Point is a north-facing setup, so its most consistent surf arrives with the winter Northeast Monsoon. From November through February, the Siberian high pumps cool, dry air southeast across the South China Sea, generating a constant ENE/NE sea and swell. The average wave height climbs to 4ft (1.2m) or more, periods run 9-10s, and occasional N/NNE or NW/NNW groundswell can push in. True quality, however, depends on those windows when the wind swings offshore from S/SSW/SW; such days are limited (18-28% of the time), but they are the reason to pull the trigger. This is the spot's best chance for solid, rippable surf.
Fair Surf Season (March - May and September - October)
The transition months trade size for clean conditions. In March, the monsoon weakens but still delivers 3ft (1m) swell. April and May see ideal wind percentages jump to 39% and 59% as E/SE/S winds dominate, but wave heights drop to 2-3ft (0.6-0.9m). September and October are the mirror image: long-period energy starts returning, periods reach 9.9-10.2s, and more N/NNE/NNW swell appears, while the wind is still relatively light and offshore. Expect groveling to fun, high-quality small waves rather than heavy barrels in these months.
Low Surf Season (June - August)
The summer Southwest Monsoon settles in and Jelly's Point goes into a flat spell. Average swell heights bottom out at around 2ft (0.6m), with periods in the 8.6-9.6s range. Winds are often favourable - S, SSW and SSE directions dominate - but there simply isn't enough energy to get the banks working. Unless a tropical cyclone drifts close enough to inject a west/northwest swell, this is a time for longboard cruising or planning a trip elsewhere.
