Conditions at Yo-Yos in August

August: Mostly Messy

August continues the mid-year monsoon pattern. The swell remains at a hefty 1.7m (5.5-6ft / 1.7-1.8m) average with a 14.4s period, and the direction is increasingly SSW (78.2%). Yet the wind is the story: SE (51.5%) and ESE (33.2%) blow almost constantly, producing ideal conditions just 7% of the time - near the yearly low. The ocean surface is often heavily textured, making it difficult to find any clean, groomed waves. On the bright side, there is virtually no rain (0.36mm/day), water is 27.4°C, and air temps are moderate at 24.7°C. The only reliable surf sessions are at dawn, before the trade wind kicks up.
