Conditions at 8th Street Jetty in May
May: Groveling Begins
May is when 8th Street Jetty transitions into early summer. Average swell height drops to 3.3ft (1.0m) and period stays at 7.2s - fun, rideable conditions for a log or fish, not a time to chase big faces. The good news: E/ESE/SE swell becomes even more prevalent, totaling over 50% of observations. The bad news: much of it is short-period, 0.5-1m stuff generated by local offshore winds and dying low-pressure systems. Wind scores are moderate, with ideal offshore wind at 37%; SSW (9.6%) and SW (7.8%) breezes add some texture, but the W/NW quadrants still show up enough. Air temps warm to 13.8°C, water climbs to 12.7°C, and precipitation eases to 3.06mm/day. If you simply must surf, target the early mornings before the summer southwesterly seabreeze kicks in.
