Conditions at Yumuri in May
May: Summer Lull Begins
May sees the surf shrink further to an average of 2.5ft (0.8m), with periods holding at 5.9s-about as short-period as it gets. The swell is dominated by ENE at 64%, but E and ESE swell combine for another 22%, a sign of the tropical trade wind pattern settling in. Wave heights are mostly in the 2-3ft (0.5-1m) range, with only a small percentage reaching 3-5ft (1-1.5m). The wind statistics show a slight improvement in offshore frequency at 10%, but the energy is too weak to produce much more than micro-ramps and grovelers. Precipitation jumps to 3.10mm/day, and water temperature is a warm 26.8°C. It is the beginning of the low season, though the fun-sized waves can still be playful on a good longboard if you pick your tide and wait for a light south wind.
