Broken Head seasonal overview

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.

Conditions at Broken Head in August

August: Late Winter, Swell on the Turn

August sees a slight easing of the winter grip. Average swell height dips to 1.5m and period to 9.3s – still good, but less consistent power. The dominant swell direction remains SSE (23.5%), but SE (15.3%) and E (10%) show signs of the east swell regime beginning to rebuild. Wind ideal remains high at 57%, though offshore westerlies (22.3% combined) are slightly less frequent than in July. Onshore winds from the north and east increase a bit (NNE+NE+ENE+E = 14.3%). This month offers a mix of winter south swell and the first hints of spring east swell. Wave heights are generally fun-sized (1-1.5m) with occasional pumping 2m sets. August is a transitional month – still very surfable but with increasing variability as spring approaches.
