Conditions at Pedra Branca in July
July: Peak Summer Lull and Howling Northerlies
July is the slowest month of the year at Pedra Branca. Average wave heights bottom out near 4-5ft (1.2-1.5m), and average period drops to 8.5s - squarely in the average, punchy, rideable range but lacking any serious long-period punch. The swell window is heavily constrained to the NNW/NW sides, with NNW at 54% by itself; WNW and W are only minor contributors. Wave heights are mostly 3-5ft (1-1.5m), with a healthy share of 5-7ft (1.5-2m) pulses, but the short periods mean surface chop usually dominates.
The wind is the limiting factor. Ideal wind conditions occur just 3% of the time, and true offshore ENE/E/ESE/SE flow is effectively nonexistent at less than 1%. Meanwhile, NNW wind is howling 59.4% of the time, frequently 20-40kph, with strong N and NW flow compounding the texture. Air temps peak at 20.2°C, water holds at 17.4°C, and rain is almost absent at 0.15mm/day. July is best saved for a longboard or a dawn patrol if some stray south or west swell sneaks in; the days of grinding Pedra Branca tubes are still months away.
