October: The Trade-Wind Squeeze
October is a frustrating month at Itapeva because there is still plenty of swell, but the winds turn against the spot. Average swell height is 1.7m (5.5ft), yet the period drops to 8.6s and ideal wind plummets to 16 percent. ENE is the dominant swell direction at 22.2 percent, with E at 20.5 percent, ESE at 14.1 percent, SE at 12.6 percent and SSE at 11.7 percent. There is legitimate size - especially from the ENE and E sectors - but NE winds blow 29.6 percent of the time, and ENE adds another 12.6 percent, so most days are lumpy and sectiony. The offshore W/NW flow is very limited, and the onshore E/ESE/SE/SSE component sits around 14 percent. Morning windows and the occasional cold front are the only real opportunities. Water temperature is 18.8°C, air averages 17.8°C, and spring rain at 5.14 mm/day often accompanies frontal passages.
