March: Maximum Long-Period Punch Before the Shift
March is the last full month of the dry season, and it trades a little cleanliness for a meaningful jump in size. The average swell height increases to 1.1m and the period lengthens to 13.5s, with the SSW direction accounting for an incredible 93% of all swell. A full 57% of the surf is now in the rippable 3-5ft (1-1.5m) range, and the structure is powerful and well organized. Ideal wind is still excellent at 41%, with the N/NNE/NE/ENE offshore flow present early in the day, although the S/SSW onshore component is starting to creep in. Precipitation remains low at 0.95 mm/day, air temperatures average 28°C (22-34°C), and the water has warmed to 29.0°C. March is the best balance of size and clean conditions on the calendar.
