Conditions at Sele in May
May: Small Groundswells and Long Days
May is defined by diminishing returns. Average swell height is 0.8m (2-3ft), average period drops to 6.8s, and the wind is ideal for surfing only 7% of the time. The vast majority of energy comes from the northwest: NW alone piles up 28.4% and WNW adds 16.2%, while W manages just 10.6%. This northwesterly windswell arrives with a raw, onshore texture and less of the clean western punch that Sele really loves.
The prevailing wind regime is strongly NNW at 26.9%, with NW at 13.2%, which puts most of the beach in a bumpy sideshore zone. Offshore windows from E and ESE exist but are short-lived. The saving grace is milder weather: air averages 9.2°C, sea temps warm to 9.0°C, and precipitation is low at 2.61 mm/day. It is not a month for serious surf missions, but the endless daylight of a Norwegian spring makes the occasional clean, soft day an enjoyable longboard session for the optimistic local crew.
