Mekakoz seasonal overview
Best Surf Season (October - March)
The heart of the northern winter is the prime time for Mekakoz. As the North Atlantic basin turns hyperactive, powerful low pressure systems march eastwards and generate long period NW and WNW swells that line up perfectly with the beach's north-west exposure. Average wave heights climb through the 5-7ft (1.5-2.1m) range with periods between 11 and 13 seconds, putting this stretch of the Spanish coast on the map for serious winter sessions. With the Azores High often displaced south or west, the pressure gradient tightens, and we see frequent frontal passages. The key is to sit out the storm fronts and grab the windows of S/SW offshore flow that groom the swell into clean shapes. Ideal wind frequencies peak at 30-38% during this season, and water temperatures between 12.6 and 14.0°C (54.7-57.2°F) warrant a solid wetsuit. This is the most consistent, powerful and hollow period of the year at Mekakoz.
Fair Surf Season (April - May & September)
As the ocean transitions between winter muscle and summer lull, Mekakoz still receives a solid dose of northwest swell, but periods drop to the 9-11s range and average heights ease down to 4-5ft (1.2-1.4m). During these shoulder months, the North Atlantic is less organised, with fewer deep lows and a more persistent Azores High often steering storms further north. The swell direction stays remarkably dominant from the NW - over 80% of the energy in April and May - so the beach still sees rideable waves. The trade-off is an increase in NW/NNW wind days as the synoptic pattern shifts, meaning those same optimal swells often arrive with onshore texture. Still, when the breeze clocked to the south, the lineup cleans up nicely, and the milder air and water temps make for more comfortable sessions. September sees a similar regime, but with higher odds of offshore conditions (36% ideal wind) as autumn begins to reawaken the Atlantic.
Low Surf Season (June - August)
The summer months are the quietest of the year at Mekakoz. The North Atlantic storm track retreats to high latitudes, and the swell generator essentially switches off. Average wave heights drop to a modest 3ft (1.0m), and periods dwindle to 8.8-9.2s, producing small, short-period waves that rarely offer the power Mekakoz is known for. The predominant swell direction is still NW - in fact June and July see over 94% of the wave energy arriving from the western/northwestern quadrant - but the lack of storm energy means those are mostly 2-5ft (0.5-1.5m) wind-swell pulses. Worse, the thermal low over the Iberian Peninsula and the strengthening of the Azores High bring a persistent NW/NNW wind pattern, which blows directly onshore at this exposed beach. Ideal offshore winds from the S/SW drop to just 7-9% of all wind observations. If you're chasing a session, the summer is a waiting game, usually for the rare long-period southwesterly groundswell or a stray tropical system, rather than a reliable surf season.
