November: Trade Winds Return, Windows Shrink
November is where the summer pattern begins to reassert itself. The average swell height drops to 1.3m (4ft), the period shortens to 8.5s, and ideal wind time plummets to just 16 percent-the lowest of the year. The swell direction is still dominated by E (24.2 percent), ESE (21.9 percent), ENE (18.6 percent), and SE (14.4 percent), but the source has shifted from deep-ocean cyclones to windswell generated by the strengthening South Atlantic high. The S and SSE swell percentages fall off significantly (4.4 and 11.5 percent), so the raw power of winter is gone. Meanwhile, NNE winds are relentless at 24.9 percent, with NE at 11.8 percent adding to the onshore/cross-shore chop. SSW winds (10.7 percent) provide occasional relief, but the westerly offshore windows are few and far between. Air temps climb to 20.4°C, water warms to 22.1°C, and rain becomes more typical. November is still surfable-especially when an early-season cold front sneaks through-but the quality is inconsistent and requires patience.
