Conditions at Cap Gris-Nez in July
July: The Seasonal Floor
July is the deepest part of the summer low. The average swell height bottoms out at 1.5ft (0.5m), average period weakens to 4.8s, and only 5% of the time is the wind truly ideal. SW (29.9%) and WSW (14.5%) dominate the wave rose, but those are the wrong directions for Cap Gris-Nez; the north window still contributes 35% of observations, yet nearly all of it is below 2ft (0.5m). On the wind side, WSW is dominant at 25.9%, with SW at 17.4%, while the bad northerly sector is less active than spring. Air temps peak at 17.1°C and water reaches 17.8°C. If the North Sea can scrape up any small N/NNE windswell, a foamie or longboard session is possible, but this month should be graded on charm, not size.
