Conditions at Mareta in May
May: Small Windows and the First Summer Blush
May sees a noticeable drop in energy: average swell height falls to 5ft (1.6m) and period drops to 9.8s. The rose is still centered on NW (39.7%), NNW (23.9%) and WNW (16.7%), meaning the magic south/southeast directions are very rare. The winds, however, are increasingly strong from the north - NNW (41.6%), NW (14.2%) and N (4.7%) - creating classic offshore surface conditions that can make even smaller days look inviting. The ideal wind score holds at 24%. Water temps warm to 17.0°C and air averages 17.6°C, so the dawn patrol is a pleasure, but bring a groveler and manage expectations until the south pulses return.
