Conditions at Gilleleje Havn in July
July: Warm Water, Flat Seas
July is the warmest month, with average air temperature 17.5°C, water temperature 18.0°C and precipitation around 2.4mm/day. That makes it pleasant for a swim, but poor for surfing. Average swell height is about 1.5ft (0.4m), average period 3.6s, and the wind is ideal for surfing only 1 per cent of the time. The wave direction distribution is loaded toward WSW, W and WNW, with W at 16.4 per cent, WNW at 17.8 per cent, WSW at 12.5 per cent, NW at 8.4 per cent and NNW at 6.7 per cent. Although these are the dominant windsea directions, the short periods and small heights produce messy, grovelling surf. The dominant winds are W, WNW, WSW and NNW; afternoon sea breezes often develop and add extra chop. If you are chasing waves in July, look for a passing low that briefly turns the wind offshore, then be ready to surf 1-2ft (0.3-0.6m) slop on a longboard.
