Conditions at Roads End in May
May: The North Wind Takes Over
May is the unmistakable start of the low season. Average swell drops to 1.6m (5.2ft) and period eases to 10.8s, moving the surf out of the powerful category and toward smaller, more wind-swell-driven waves. The raw direction mix is still good - W 31.9%, WNW 33.6%, WSW 12.6% and NW 11.8% - but the engine behind the waves is weakening. Wind is the real problem: NNW becomes the dominant direction at 32.8%, while ideal offshore ENE-to-SE winds are down to 14%. The daily cycle of afternoon north wind creates bumpy, sectiony conditions; dawn patrol is the only consistent way to find clean, rippable waves. Water temp climbs to 11.8°C, air to 11.0°C, and rainfall down to 2.45 mm/day signals the dry season ahead.
