Conditions at Omaezaki in March
March: Spring Transition Begins
March is the first month where the S/SW swell window truly starts to challenge the winter W/NW pattern. S 5.8%, SSW 7.9% and SW 6.6% combine for roughly 20% of all swell energy, while W/WNW drops to around 25%. The average period jumps to 7.6s, giving the waves more push than the dead winter months. Swell heights remain at a fun-sized 1.3m average, with a broad spread of 0.5-1.5m plus a solid pocket of 1.5-2.5m from the SSW/SW quadrants.
Winds are still predominantly WNW (25.6%) and W (14.1%), but ENE at 11.1% reminds us that warmer spring regimes are arriving with more rain and unstable skies. With ideal wind at 18%, March rewards patience: catch a N/NNE offshore morning, pick out a S/SW swell, and there are genuinely good, clean waves to be had. Air averages 12.0°C and water 15.1°C.
