Conditions at Ervik in May
May: The Summer Fade Begins
May is a classic shoulder month: all the ingredients are present, but the portions get smaller. Average swell height eases to 3.3ft (1.0m), and period falls to 8.5s, pulling most surf back into the average, punchy range. The good N/NW directions actually dominate the swell rose - NNW at 22.0%, NW at 11.2%, WNW at 10.0% and N at 7.8% combine for 51% - but the energy is mostly in the small 2-5ft (0.5-1.5m) class. This is fun, rippable, groveling-style surf rather than the heavy winter wedges.
Wind becomes split between NNE/NE flows typical of spring high pressure and SSW at 14.7%. Ideal conditions clock in at just 14%. Air temperatures warm to 8.0°C, water temperature reaches 8.0°C, and precipitation is at a spring minimum of 3.17mm/day. If you time it right, clean shoulder-high waves on a longboard are definitely on; just do not book the trip expecting overhead grinders.
