Conditions at Sidi Moussa d'Aglou in December
December: Peak Season Holds the Crown
December is statistically the cleanest month of the year at Sidi Moussa d'Aglou. The average swell height sits at 6.5ft (2.0m), the period is a robust 12.9s, and the swell distribution is broad and favorable: northwest and north-northwest each supply 32 percent, west-northwest adds 12 percent, and even a touch of west swell sneaks in. That combination produces consistent, powerful, head-high-to-overhead surf with excellent long-period energy.
What really sets December apart is the wind. Offshore E/ESE/SE/SSE directions account for roughly 47 percent of all observations, and an exceptional 56 percent of the time the wind is ideal for surfing. Onshore northwesterlies are the minority for the only time in the year. Air temperature is cool and invigorating at 17.7°C, water is 17.9°C, and rainfall averages 1.02 mm/day. For a NW-facing Moroccan beach, December is about as close to a flawless combination of size, period, direction, and wind as you are likely to find.
