Conditions at Cloud 9 in August
August: Typhoon Season Sparks Begin
August remains small on average at 2ft (0.7m), but the pulse is starting to change. The average period rises to 9.0s, and the swell rose broadens: ENE (26%), E (19%), NE (10%), plus a noticeable bump of SSW-to-W energy from passing typhoons and tropical storms across the Philippine Sea. This is when the first serious long-period waves can sneak in if a cyclone tracks along the eastern edge of the archipelago and points its fetch toward Siargao. Wind is at its most favorable all year, with 60% ideal offshore conditions, so the surface is frequently glassy even when the size is small. Water is a warm 29.3°C, air 28.1°C, and rainfall is relatively low at 5.7mm/day. Stay alert to typhoon forecasts-one well-placed storm can turn the month from groveler to firing.
