Dungeons - surf spot statistics

Best Surf Season (May - August)

Winter in the Southern Hemisphere is prime time for Dungeons. The long-fetch swells generated by the Roaring Forties become a consistent presence, with average heights pushing above 2.6m and periods often exceeding 12 seconds. The ideal offshore wind from the north to northeast quadrant becomes more frequent as strong high-pressure systems stall over the interior, occasionally setting up clean conditions. While the percentage of perfect wind remains modest (up to 22% in June), when it aligns with a solid SW to SSW groundswell, the wave quality is simply world-class. This is the time to charge.

Fair Surf Season (March - April & September - October)

These transitional months see the swell machine still active but less consistent. Average heights linger around 2.4-2.7m with solid periods, but the wind patterns are more chaotic. The transition between summer and winter circulation brings a mix of onshore SE trades and the first or last pushes of cold fronts. While you won't score the pumping consistency of winter, the cleaner windows offer fun, powerful surf, especially when a passing front clears the air and delivers a crisp north wind. It's a gamble, but the rewards can be good.

Low Surf Season (November - February)

The summer months are the most challenging for surfers at Dungeons. Average swells drop to around 2.3m, and the wave period sits in the 11-second range – still punchy but less powerful. The bigger issue is the wind: persistent SE to SSE winds (often over 30kph) blow directly onshore, ruining wave quality. The ideal offshore wind from the north occurs only 5-6% of the time. While occasional southerly swells do arrive, they are usually accompanied by onshore conditions. This season is defined by waiting game – best for the patient surfer who can spot a rare north wind window.

January: The Summer Trade Wind Blues

The heart of summer brings a mean swell of 2.3m at 11.1 seconds – a solid basis, but the persistent SE to SSE winds (37% from SSE alone) turn any potential into a battle. These winds blow directly onshore at the SSW-facing spot, creating choppy, lumpy conditions. Groundswell from the SW and SSW quadrant dominates (over 45% of the swell energy), but it's largely unsurfable unless a rare north wind materializes (only 1% from N). The few ideal days occur when a coastal low clears the air, but they are fleeting. It's a month for the patient.
