March: Bigger Swell Mixes and the First Onshore Battle
March sees the average swell height nudge up to 1.0m (3ft) with a 12.5s period. The direction spread broadens with WSW at 42.9%, W at 33.4% and SW at 18.4%. There are also more sets in the 1.5-2m (5-6.5ft) range from the W and WSW directions, making this one of the more powerful months of the year for raw west groundswell. However, direction is not always ideal, and the west-heavy mix needs some west-southwest angle to really light up the spot.
Wind becomes the limiting factor. Ideal offshore flow drops to 21%, while W wind reaches 21.3% and WSW wind reaches 12.8%. Afternoon sea breezes are increasingly common, so dawn patrol is critical. Air temperature is 14.7C, water temperature is 14.2C, and precipitation eases to 1.59 mm/day. This is still a good month for bigger waves, but you need to pick the post-cold-frontal offshore windows.
