May: Winter Swell Begins to Roll, Wind Becomes the Enemy
May keeps the average swell solid at around 6ft (1.8m) with an excellent 13.6s period. This is the first month where 6.5-8ft (2-2.5m) energy becomes a significant fraction of the total, especially in the SSW bins, and nearly all of the wave train, 84%, is arriving from the SSW. Only 6.5% comes from the ideal SW window. The wind is the bigger concern: the S/SSW/SW combination jumps to over 83%, and ideal offshore wind drops to 10%. Many days will see a lumpy, wind-textured surface, but the sheer amount of long-period groundswell means the paddle-out is still on. Look for early mornings with lighter SSE/SE winds or the occasional breeze from the east. Air temperatures fall to 18.6°C, water to 17.0°C, and rainfall remains essentially zero.
