Conditions at Mirleft in April
April: The Transition Begins
April is Mirleft's shoulder month. Average swell height eases to around 6ft (1.9m) and the period drops to 10.9 seconds, which takes the surf out of the powerful long-period class and into the punchy average-to-good range. The swell machine is still fuelled by NNW (46.7%) and NW (27.9%) directions, with plenty of waves in the 1.5-2.5m (5-8ft) range - so the size is still there on paper.
The major problem is the wind. NNW wind dominates a huge 40.5% of the time and NW adds 10.8%, giving the beach long stretches of onshore breeze. Ideal offshore flow is only 21%, the lowest since the heart of winter. Most days are a short-board struggle with lumpy cross/onshore texture; the wise move is to wait for a day when the pressure gradient eases or the wind flips to S/SW. Water temperature is 17.5°C, air averages 17.6°C, and spring rains are already fading.
