May: The NNW Windswell Takeover
May officially begins the summer slide. Average height falls to 6ft (1.8m) and average period to 9.4s, meaning the swell is now more windswell than groundswell. The wave rose is wildly one-directional: 62.9% NNW and 19.3% NW, with a negligible 0.2% from due W. For a west-south-west-facing spot, this is the wrong kind of consistency - pure NNW energy has to work hard to wrap in, and the short period makes it fat. Ideal wind percentages bottom out at 36%, and the wind compass is dominated by NNW (37.0%) and NW (24.4%) breezes. When the NE/NNE offshore flow does appear, the ocean can still look pretty, but size and power are lacking. Air temperature averages 19.4°C (13.6-33.8°C), water is 17.4°C, and rainfall is only 0.28mm/day. This is the time for longboards and low expectations.
