Conditions at Sidi Moussa d'Aglou in April
April: Swell is There, Wind is Not
April is a month of abundant, sometimes excellent swell fighting a poor wind regime. Average height is still solid at 6ft (1.9m), but the average period backs down to 10.9s, still in the powerful 10-14s range yet a notch below winter authority. The swell direction tightens to the north-northwest and northwest, with NNW accounting for nearly 47 percent of all wave energy. In pure wave terms, Sidi Moussa is not the problem.
The problem is the wind. Onshore flow from the NW quadrant becomes dominant at 67 percent, with west-northwest and northwest winds packing much of the energy. Offshore E/ESE/SE/SSE winds collapse to just 12 percent, and ideal conditions crater to 22 percent. Expect bumpy, warbly faces and a lot of blown-out surf. Water temp is 17.4°C, air 18.3°C, and precipitation drops to 0.43 mm/day. Wait for a rare offshore pulse if you want it clean.
