July: Mid-Summer Trade Wind Grind
July is the most challenging month for consistent quality at Shipwreck Beach. The average swell is still 5.5ft (1.7m), but the period falls to 9.2s and the spectrum is overwhelmingly E and ENE windswell, with E alone at 51.2 percent. Direct south swell is virtually nonexistent in the climatology, so the beach has to work with low-energy trade swell that rarely lines up well. Wind is the bigger story: ENE blows 79.8 percent of the time, the highest of any month, and the ideal offshore wind percentage bottoms out at 11 percent. The little windows of opportunity usually arrive at dawn before the trades overpower the surface. Water temps climb to 26.1°C, air temps average 25.5°C, and precipitation stays low at 1.2 mm/day.
