Essaouira seasonal overview
Best Surf Season (October - March)
Essaouira's west-facing coastline sits squarely in the firing line of North Atlantic winter storms, and from October through March the region sees the most consistent combination of size, period and clean offshore wind. Average wave heights hover around 1.8-2.3m (6-7.5ft) and average periods climb into the powerful 11-13 second band, with the bulk of the energy arriving as long-period WNW and NW groundswell. When the Azores High relaxes and Atlantic lows push farther south - especially during negative phases of the NAO - the Moroccan coast gets hit by multiple-day windows of pumping, well-ordered waves. The prevailing continental flow from the east and southeast adds an offshore component that keeps the faces clean and hollow, making this the clear go-to season for serious sessions.
Fair Surf Season (April and September)
The shoulder months of April and September offer a mixed bag. April still sees plenty of swell from the winter swell machine - average heights around 2.0m (6.5ft) - but the wind regime begins to veer north and northeast as the Azores High builds, dropping the ideal-wind percentage to 25 percent and adding texture to the surf. September sees the ocean re-awaken: the average period climbs from the summer doldrums to 10.1 seconds while heights hold at 1.6m (5.2ft), but the trades are still hanging on and swell quality is less reliable. Watch for early-autumn storm pulses that start to align with offshore wind windows.
Low Surf Season (May - August)
From May through August, Essaouira slips into its low season. The Azores High muscles north and the Icelandic Low weakens, shifting the local wind to a persistent N and NNE trade regime that only blows offshore about 17-23 percent of the time. Swell heights drop to a modest 1.6-1.7m (5-5.5ft) and periods fall to the windswell range of 7.6-9.4 seconds. Most waves are short-interval NNW windswell - punchy but fat, closey and hard to ride on the better peaks. Early morning can still offer glassy, rideable conditions before the trades crank up, and the warm water and air make summer a fun beach day, but serious surfers should look to other seasons for quality.
