Conditions at 8th Street Jetty in January
January: Deep Winter Consistency
The new year kicks off with a solid late-winter baseline. Average swell heights hold at 4.3ft (1.3m) and periods average 6.9s, so most of what arrives is short-to-average period windswell and low-end groundswell rather than long-period perfection. Directionally, the Atlantic is split: while optimal ENE/E/ESE/SE swell makes up a little less than a quarter of the spectrum, the S/SSW/SSE swells (roughly 27% combined) add southern energy that the Jetty can only partially pick up. The wind pattern is your friend - WNW (15.8%), NW (13.4%) and W (13.7%) combine for a strong offshore signal, and overall ideal winds blow 38% of the time. The catch is the cold: air temps average 2.8°C, water temps drop to 5.8°C, and precipitation 3.29mm/day keeps the atmosphere raw. Look for post-cold-front windows where fresh W/NW offshore winds line up with an E/ESE fetch; those are the sessions that make January worth it.
