October: The North Pacific Reawakens
October is when Shipwreck Beach starts to wake up. Average swell height jumps to 6.5ft (1.9m) and the period lengthens to 10.8s as the first powerful North Pacific lows organize. The swell window shifts from a pure east trade wind spectrum back toward ENE, NE, and NNE, with NNW contributing 9 percent of the directional total and the first wrapping winter lines showing up. The trades remain the background wind, but ENE presence drops to 54 percent and ideal offshore flow stays around 23 percent, giving more opportunities for clean conditions. When a strong storm system aligns, this month can produce surprisingly good long-period waves under near-offshore winds. Water temps remain warm at 26.6°C, air averages 25.7°C, and rainfall picks up slightly to 1.9 mm/day.
