Conditions at Yumuri in August

August: Hurricane Season Rumbles in the Distance

August looks a lot like July, with average surf at 3ft (0.9m), periods at 6.0s, and ENE swell accounting for 81% of the wave-energy distribution. The majority of days are small to solidly fun-sized: nearly half the month sees 2-3ft (0.5-1m), and another 24% is in the 3-5ft (1-1.5m) range. Winds stay locked out of the ENE at 54%, with E at 19% and NE at 13%, meaning the ocean is almost always textured by trade wind chop. Ideal offshore wind shows up only 8% of the time. August is also when the Atlantic hurricane season begins to wake up. A passing storm can produce a sudden burst of E/NE swell and heavy winds, but the direction rarely works in Yumuri's favor. Water temperature reaches a warm 28.3°C, air temps are 28.1°C, and precipitation climbs to 2.35mm/day.
