October: Spring Size Meets Onshore Trade Winds
October is a frustrating month in many ways. The swell factory stays active -- average swell is around 5-6ft (1.5-1.8m), and the E/ENE/ESE window is loaded, with E and ENE combining for over 42 percent of the wave energy. There are plenty of 5-6.5ft and 6.5-8ft waves, and the average period of 8.6s still has some punch. On paper, the beach looks fun.
But wind quality collapses. NE is the dominant wind at 27.6 percent, ENE adds another 16.9 percent, and the offshore W/NW quadrant accounts for only about 7 percent of readings. The ideal wind score drops to 17 percent, one of the lowest of the year. That means much of this solid swell arrives windblown and cross-shore. Water temperature warms to 18.7°C, air temperatures average 17.8°C (ranging from 6.8°C to 31.9°C), and precipitation is the highest of the year at 5.14 mm/day. October requires patience and a keen eye on the synoptic chart.
