Conditions at Razo in May
May: Smaller Swells and a Shifting Wind Battle
May marks the real slide into the shoulder season. Average swell height drops to 6.2ft (1.9m) and average period falls to 9.8 seconds. The direction mix is still very surfable, with WNW at 17.8%, NW at 17.6%, and NNW at 15.8%, plus W at 11.3% and NNE at 7.4%. There is no shortage of swell, but it is generally smaller and shorter-period, producing more rippable and less intimidating conditions than the winter months.
The wind becomes the limiting factor. NE winds are now the dominant signal at 17.4%, and NNE is close behind at 14.9%. Offshore SW and SSW winds combine for around 19%, but clean windows shrink to 20% of the time. This means Razo can be fun, groveling and occasionally good, but consistency suffers. Water temperature rises to 14.8°C, air temps average 14.4°C, and rainfall drops to 2.34 mm/day. Look for light south winds and small to mid-period NW swell for the best May sessions.
