Conditions at Gruissan in July
July: Micro Swell and Thermal Chop
July is the heart of the Mediterranean summer doldrums. Averages sit at 2ft (0.6m) with a period of just 4.1s, and ideal wind is only 12%. The dominant swell signal is split between WNW/NW windsea, 42% combined, and a large frequency of SE/SSE/S swells, but the height classes tell the story: nearly all of this energy is under 1m and most sits around 0.5m. Gruissan's east-southeast-facing sandbars still see some tiny peaks, but they are short-period, soft, and quickly chopped by afternoon onshore seabreezes. The Azores High rules, precipitation drops to 0.64 mm/day, and water temperature peaks around 22.1°C. Air temps average 23.5°C, making it perfect beach weather but frustrating for surfing.
