July: Consistent SSW Groundswell and the Mid-Year Grind
July continues the rainy-season pattern with consistent south swell. Average height holds at 4.5-5ft (1.4m), period is a solid 13.4s, and SSW remains the workhorse at 93.4%. The S direction is more involved than earlier in the year (3.2%), with about 1.2% in the 5-6.5ft (1.5-2m) class, while the main SSW band pushes 20.9% into that same size range. The bottom line: there is nearly always rideable, long-period swell rolling into the beach.
Wind quality is low, with ideal surf wind at only 26%. The pattern is messy and mostly onshore: SSE (11.1%), SW (11.0%), S (10.2%), SSW (10.2%), WSW (10.3%) and SE (9.4%). Heavy rain and frequent thunderstorms add fresh wind to the nearshore zone, so you'll need patience and a keen eye on the local forecast. Air temp averages 25.9°C, precipitation is 7.65mm/day, and water temp stays at a warm 29.0°C.
