July: Biggest Swell of the Year, Messier Conditions
July marks the peak of the average swell-height curve at 3.9ft (1.2m), with the period easing to 13.0s. The S direction is now the dominant swell engine, delivering 73% of the energy, and 48.1% of all waves are in the 3-5ft (0.9-1.5m) range. There is also a credible 4.3% portion in the 5-6.5ft (1.5-2m) class and even a few 6.5-8ft (2-2.5m) outliers. This is the largest, most powerful wave window of the summer. However, ideal wind frequency remains low at 40%; SE, SSE, S and SSW winds fill the rose, leaving little room for the offshore W and NW flow, and the surface often stays lumpy.
Air temperatures reach 28.3°C, water temperature climbs to 28.5°C, and precipitation increases to 0.69mm/day as tropical moisture enters the picture. The best scenario is an early-morning glass-off or a temporary NW or WNW offshore breeze in the wake of a tropical wave. If you can find those clean windows, July offers some of the heaviest, most powerful surf of the year-just be ready for the humidity and summer squalls.
