Broken Head - surf spot statistics

Best Surf Season (April - May)

Autumn delivers the sweet spot at Broken Head. As the Tasman Sea cools and the subtropical ridge migrates north, a favorable synoptic pattern emerges. Offshore winds from the west (SW, WSW) become more prevalent, clocking in at over 44% ideal conditions in April and peaking at 57% in May. Meanwhile, the dominant swell directions shift from the pure east to a more ESE and SE component, but the east quadrant still pumps solid 1-1.5m groundswell at a punchy 9s period. This combination yields clean, rippable waves that peel perfectly along the headland. Expect fun-sized to good waves with occasional pumping sets when deeper low-pressure systems slide past New Zealand.

Fair Surf Season (March & June - September)

March offers the tail end of summer swell with wind still inconsistent (27% ideal), while the winter months from June to September bring a dramatic increase in offshore wind frequency – up to 68% in June. However, the swell direction takes a southward turn. The dominant swell trains shift to SSE, SE, and S (over 50% of the total in June), which means Broken Head receives more southerly energy that wraps around but lacks the full power of an east swell. Wave heights remain solid in the 1-1.5m range with periods averaging 9-9.6s – powerful but often bumpy due to the swell angle. September sees a transition with improving wind and more east swell returning, making it a fair bet for the patient surfer.

Low Surf Season (October - February)

Summer and early autumn are challenging at Broken Head. From November through February, the wind is ideal only 19-25% of the time, with strong northeasterly sea breezes (N, NNE, NE) dominating over 30% of the days – these are directly onshore for this east-facing spot. Swell is still present – mainly from E and ESE (January has 26% from E, 22% from ESE) – but the combination of onshore wind and often shorter-period trade wind swell (periods around 8.2-8.6s) creates messy, choppy conditions. October sees a slight improvement as winds start to back off, but it remains inconsistent. Only the occasional winter swell remnant or tropical cyclone event can produce good waves, but they are rare. Generally, this is a time to seek shelter or explore other breaks.

September: Spring Shift, Mixed Bag

September is the classic spring transition month. Average swell height holds at 1.5m with period 8.8s, indicating a mix of long-period winter leftovers and shorter-period trade swell. Swell direction shifts noticeably north: NNE (10.3%) and NE (9.2%) appear for the first time in significant numbers, while E (11.6%) and ESE (11.1%) also contribute. The SSE direction (21.1%) is still the top, but the spread is wide. Wind ideal drops to 44%, with offshore westerlies (11.8% combined) becoming less dominant. Onshore winds (N, NNE, NE, ENE, E, ESE) total 45.4% – again a challenge. This leads to a mixed month: some days deliver clean east swell with westerly winds, others bring sloppy onshore conditions with short-period windswell. The best luck comes from tracking synoptic patterns; a high-pressure system settling over the Tasman can unlock excellent surf.
