Conditions at Topanga Beach in May
May: Summer Wind Takes Over
May is when the summer onshore regime locks in. Average swell height remains 0.9m (3ft) with a 12.0s period, and the swell mix features WSW (40.2%), W (29.3%), SW (24.2%), and SSW (6.0%). There are still some fun 1-1.5m (3-5ft) waves from west and WSW, but the wind quality collapses: ideal wind is just 24%.
Southwest (16.3%) and WSW (17.4%) winds dominate, with additional onshore flow from W (10.2%) and SSW (9.2%). These winds put a chop on the surface and make Topanga feel much smaller than the raw swell statistics suggest. Water temp edges up to 14.0°C and air temps average 17.1°C with little rain. The best windows are early mornings before the sea breeze kicks up.
