The Island • Surf Spot Statistics

Best Surf Season (April - August)

When the Southern Ocean begins to wake from its summertime slumber, The Island's SSE-facing bank switches on. From April through August average wave heights run 6-7ft (1.8-2.1m) with average periods pushing from 10.7 up to a wintertime peak near 11 seconds. The subtropical ridge drifts north, allowing frontal systems and deep Tasman Sea lows to aim long-period S and SSE swell straight at the coast. Onshore wind frequency stays relatively low, and the offshore NW/NNW flow still blows around a third of the time. Water temps drop from 18.5°C to 13.5°C, but the reward is powerful, organized groundswell on a beach that handles southerly energy beautifully.

Fair Surf Season (March & September - October)

March belongs to autumn in transition: the first genuine long-period swells arrive, but lingering S/SSW onshore flows complicate the picture. September and October are the spring mirrors of that - the ocean is still full of S/SSE groundswell from winter, yet the shorter days and warmer sun bring lighter winds. On average you'll see 5-6ft (1.5-1.8m) surf at 10.3-10.5s, with the best windows occurring when NW/NNW offshore winds groom the S/SSE swell. These months reward patience: when the synoptic setup aligns, the quality can equal the heart of winter.

Low Surf Season (November - February)

Summertime high pressure rebuilds over the Tasman and the major storm tracks retreat south. November through February sees average heights settle at 5ft (1.5m) and periods dip under 10 seconds. Swell direction shifts easterly and northeasterly - not ideal for an SSE-facing beach - so much of the mixture becomes smaller, softer and less organized. That said, the N/NNE offshore flow is still a regular morning visitor, and when the right combination of small SE groundswell and clean offshore wind lines up, The Island offers fun-sized rippable waves. Just don't expect the winter juice.
