August: Late Summer Grind With a Pulse of Life
August remains firmly in the low season, but there are small signs of life. The average swell height is still around 4-5ft (1.2-1.5m), and the period ticks up slightly to 8.9s. Swell energy still arrives from NNW and NW - over 85% of the observations - with a growing WNW component of 10.2% and a little more west in the mix. Most waves are in the 3-5ft (1-1.5m) range, though the 5-7ft (1.5-2m) ranks remain well represented, particularly under stronger NW pulses.
Wind conditions remain poor: ideal flow is just 5%, and offshore ENE/E/ESE/SE winds total under 2%. The northerly trade machine is still dominant, with NNW at 54.7% and N at 15%. Water temperatures reach their warmest of the year at 17.8°C, air temperatures average 20.7°C, and precipitation drops to 0.25mm/day. Near the end of August, the first subtle increases in period and the occasional west-based swell signal that the autumn campaign is not far away.
