Conditions at Rhossili Bay in July
July: Peak Summer Lull and Onshore Winds
July is the most challenging month for surfers at Rhossili. Average swell height bottoms out at 0.7m (2.3ft) and average period at 7.4s, the lowest of the entire year. The wave rose is dominated by W (33.8%) and WSW (43.8%), but almost all of that energy is below 1m, with micro-swell conditions prevailing. Meanwhile, the wind picture is ugly: S/SSW/SW/WSW onshore wind directions account for over 36% of the hourly data, the highest of any month. Add in summer heating and you get a recipe for small, wobbly, wind-blown surf. Ideal offshore wind drops to just 6%. There are still rare days when a summer low or tropical-origin swell sends pulses of longer-period W/SW energy into the bay, and early-morning NE/E offshores can turn the micro-swell into fun, rippable wedges. But for serious surf, July is best spent checking the cams and waiting for the Atlantic to wake up.
