Conditions at T-Street in March
March: Max Swell Size, Shrinking Offshore Windows
March sees the highest average swell height of the year at 1.0m (3.3ft), with WSW delivering 42.9% of the energy, W 33.4% and SW 18.4%. The average period remains a solid 12.5s, so the bigger waves carry genuine long-period power. Expect more head-high sets in the 3-5ft (0.9-1.5m) range, with occasional larger 1.5-2m waves on the W and WSW windows. The trade-off is that ideal wind drops to 32% as the onshore flow strengthens - WSW and W winds combine for nearly 30% of the wind rose. Rain eases to 1.50mm/day, air temps warm to 14.3°C, and water temp holds at 14.2°C. The best March sessions come with dawn patrol NE offshore winds before the afternoon westerlies flatten and lump it up.
