Conditions at San Pedrito in May
May: Southern Hemi Season Starts
May is one of the cleanest months of the Southern Hemisphere swell season. Average size remains 4-5ft (1.2-1.5m) and the 13.8s average period is still solidly long-period. The big story is direction: WSW (38 percent), SW (33 percent), W (20 percent) and SSW (6 percent) put roughly three-quarters of the wave energy into the optimal SSW-SW-WSW band. Wind quality drops only slightly to 56 percent ideal, but the flow is mostly NW (39 percent), WNW (28 percent) and NNW (26 percent)-cross-shore rather than full offshore. Air temperature averages 24.5°C, water temperature warms to 21.8°C, and precipitation is essentially zero. San Pedrito grooves with long, clean lines, especially in the morning before the thermal breeze gets going.
