May: Clean but Fading Groundswell
May marks the last meaningful connection to the winter swell machine. Average heights ease to 6.6ft (2.0m) and periods shorten to 10.6s. The swell rose becomes dominated by WNW (22.5%) and NW (19.2%), with W (16.6%) still present and NNW (9.6%) starting to add short-period summer pulses. The WSW/SW window is minor at best, so waves are more windswell-influenced and angled rather than pure groundswell. Ideal winds are 47%; the wind rose loads heavily into NNW (32.9%) and NW (16.2%). That NNW flow is cool and side-offshore, but the cleanest conditions still align with the N/NE offshore quadrant. Water temp creeps up to 11.4°C, air temp averages 11.6°C, and rainfall collapses to 1.96 mm/day. May is generally playful - not as powerful as winter, but far more user-friendly.
