Conditions at Gilleleje Havn in May
May: Spring Warmth, Minimal Waves
May offers the first real taste of spring warmth, with average air temperature 11.3°C and water temperature 10.7°C, but surf quality remains minimal. Average swell height is around 1.5ft (0.4m) with a 3.5s period, so the sea state is dominated by lumpy, short-period chop rather than actual swell. The directional distribution is centred on WNW, W, NW, NNW and WSW. This is, on paper, a better NW-oriented pattern for Gilleleje than the winter months, but the energy is too small and too short-period to make the harbour fire. Wind data show strong E/ESE/SE flow together around 24 per cent, plus a healthy W-NW component, with the ideal wind for surfing sitting at just 1 per cent. Precipitation runs about 1.7mm/day. It is a beautiful time to be outside, but the surfboard mostly stays in the car.
