Conditions at Rincao in July
July: Consistent Southerly Swell and Cool, Clean Air
July continues the winter window with average height around 5ft (1.5m) and period at 9.6 seconds. S swell remains the dominant source at 19 percent, with SSE and E both at 16 percent, and ENE close behind at 13 percent. The mix of easterly trade-swell and southern groundswell gives Rincao very consistent, punchy surf across the exposed sandbars, and the occasional SSW addition (4-5 percent) pushes in longer-period energy.
Ideal offshore winds remain strong at 43 percent. While NE flow is still present, the cool winter air (15.8°C) and water temperature of 16.5°C mean less thermal breeze and better morning conditions. Rainfall ticks up slightly to 4.03mm/day, but the frontal passages that bring rain also bring the W/NW wind that cleans up the sets. July is reliable and often heavy.
