Conditions at Ohama in March
March: Spring Transition Builds The Eastern Window
March marks a clear shift toward the east. ENE swell jumps to 14.5%, E to 9.9%, and ESE/SE/SSE combine for another 15%, pushing the preferred swell-direction share to roughly 40% if we include the adjacent ENE window. Average height stays solid at 5.5ft (1.7m), and the 7.4s period means waves are still punchy rather than powerful. Wind, however, becomes more complicated: NE at 17% and ENE at 14% are prominent, while cross-shore WSW at 15% also competes with the offshore W flow at 18%. Ideal surfing wind drops to 19%. The result is classic spring: fun E/ESE swells with occasional clean offshore mornings, but plenty of lumpy, wind-affected days as the atmosphere transitions. Air warms to 12.8°C, water sits at 16.3°C, and rainfall jumps to 5.2mm/day.
