Conditions at Mirleft in May
May: Smaller Swells and a Persistent Onshore Breeze
May sees Mirleft's surf continue to shrink and slow down. Average swell height drops to 5-6ft (1.7m) and the average period falls to 9.5 seconds, bringing more short-period, wind-driven energy into the mix. The direction mix narrows dramatically - NNW swell is 65.0% of the total, with NW at 21.6% - and although there are still rideable 1-2m (3-6.5ft) waves, they lack the heavy, organized push of winter.
The wind makes things harder. NNW winds blow 45.7% of the time and NW adds 12.5%, meaning onshore conditions are the norm rather than the exception. Ideal offshore flow plummets to just 16%. Early morning can offer a short window of lighter wind, but by midday the onshore breeze usually has the surface messy. At 17.7°C the water is still cool, though air temperatures of 19.3°C and dry skies make the beach a pleasant place even when the waves are not cooperating.
