Conditions at Thunders in March
March: Transition Month Brings Stronger Swell and More Offshore Windows
March marks the turning of the tide. The average swell height holds at 1.3m (4.3ft), but the period stretches to 12.9s, and the SSW direction spikes to 59.9% of the total, with SW a still-strong 22.3%. The mix favors the SSW-SW angles that wrap perfectly into Thunders. Wave heights are concentrated around 3-5ft (1-1.5m), and 14.6% of the time you will find 5-6ft (1.5-2m) faces on the reefs.
The shift in winds is the good news. The NW monsoon is weakening, with WNW/NW/NNW dropping to 46.6%, and the SE trades are starting to build through the ESE-SSE sector. Ideal surfing wind percentages rise to 32% as a result. You get more clean early sessions, especially when E/ENE/NNE flow kicks in before the sea breeze. Air temperatures remain warm at 27.9°C, water temperature is a balmy 29.5°C, and rain stays moderate at 7.17mm/day. It is a shoulder month where persistence pays off: enough long-period SSW groundswell to keep the break alive, and increasingly frequent windows of glassy texture.
