August: Tropical Heat and Hope
August is still low season, but the Atlantic hurricane season adds a glimmer of hope. The average swell is around 2ft (0.6m) with an 8.1s period, and favorable wind sits at 15%. The wave rose is overwhelmingly E (44.9%) and ESE (27.6%), with ENE (13.3%) next on the list; most waves remain small, but there is a slight increase in 3-5ft (1-1.5m) and 5-6.5ft (1.5-2m) ENE energy compared with June and July. The wind rose continues to favor ESE (13.4%), E (11.8%) and SE (10.2%), all blowing onshore. Yet August is also when tropical waves, storms and early hurricanes start traversing the western Atlantic. A well-tracked system can send long-period ENE/E swell into the inlet with enough size to overcome the average. Those days are rare, but when they happen they remind you what the inlet is capable of.
Water temp is the warmest of the year at 29.0°C, air averages 27.6°C and precipitation is high at 6.50 mm/day. Keep an eye on the tropics.
