Conditions at Caldera in October

October: Autumn Swell Window, Wet and Wobbly

October remains in the heart of the rainy season, with average precipitation at 7.63mm/day, the wettest month of the year. Swell is still directionally ideal: SSW at 70.8%, SW at 16.0% and S at 10.1%. The average period is 14.0s, so when a bigger pulse does arrive, it should be organized and powerful. But the average swell height is again around 1ft (0.3m), and only about 0.5% of the month falls into the 2-3ft (0.5-1m) category. The wind field is dominated by southerly to southeasterly flow, with S at 14.9%, SSE at 13.2% and SSW at 11.2%, so surfaces tend to be lumpy and cross-onshore more often than not. Water temperature cools slightly to 28.3°C. As the dry season approaches, offshore morning windows become more possible, but the monthly archive says to expect more flat, bumpy days than actual surf.
