Alvor seasonal overview

Best Surf Season (October - March)

The North Atlantic flexes its muscles during these months, with deep low-pressure systems tracking across the mid-latitudes and sending consistent, long-period swell toward the Algarve coast. Alvor's SSW orientation becomes a magnet for SW to S groundswells, often arriving with 10-14s periods and heights in the 1-2m range. The offshore wind window from the N to NNW quadrant blows clean and frequent, thanks to a well-established Azores High and cold fronts sliding south. This combo delivers some of the best, most reliable surf of the year. Expect pumping sessions from October through March, with January and December often topping the charts for both size and consistency.

Fair Surf Season (April & September)

Transition months mark a shift in the Atlantic storm track. Swell energy dips modestly, averaging 1.1m in April and 0.8m in September, but periods remain respectable in the 10-11s range. The wind regime becomes more fickle—ideal offshore days from the north occur roughly a third of the time, while warmer land temperatures can trigger afternoon sea breezes. However, when a late-season or early-autumn storm aligns with a northerly wind, Alvor can still offer fun, ripable waves with fewer crowds than the peak season.

Low Surf Season (May - August)

Summer settles in with the Azores High dominating, flattening the swell window significantly. Average heights drop below 1m, periods shorten to 8-9s, and the swell often comes from the NW — a direction that struggles to wrap effectively into Alvor's SSW-facing beach. The wind pattern holds a silver lining: thermal-driven offshore flow from the north-northwest kicks in on many afternoons, but the wave size rarely exceeds 'groveler' territory. For the dedicated surfer, it's a time to chase small-wave gear and early morning glass-offs before the sea breeze builds.

Conditions at Alvor in March

March: Transitional Grind with Occasional Gems

As spring approaches, average swell height ticks down to 1.3m and period shortens slightly to 12.1s. Ideal wind frequency drops to 35%, reflecting the shift toward more variable spring patterns. Swell from WNW (29%) and NW (27%) still dominates, but S and SW directions begin to appear more often (combined ~4.6%). This month is all about patience: the Atlantic still sends solid pulses, but afternoon sea breezes become more common. Early morning sessions with wind from N (11%) or NNW (15%) offer the cleanest conditions. Look for days when a cutoff low stalls near the Azores — it can feed Alvor with a multi-day run of mid-period SSW swell that stands up nicely on the rip-able banks.
