March: The Season Shifts Into Gear
March is where the swell curve starts to steepen. Average height ticks up to 3.6ft (1.1m), and average period jumps to 13.5s-now comfortably in the powerful long-period class. The real story is the distribution: 51.7% of the waves come from SSW in the 3-5ft (1-1.5m) range, and another 1.9% push into the 5-6.5ft (1.5-2m) range. SW delivers another 8.7% at 3-5ft. In total, well over 60% of the swell is at least head-high and holding. The wind picture is still good-25% ideal offshore flow, with N-NE breezes in the morning before a light S/SW sea breeze kicks up. Rain remains low at 0.95mm/day, and 28.9°C water makes it feel like summer. This is the first month of the real surf season.
