Neminja - surf spot statistics

Best Surf Season (October - March)

The North Atlantic flexes its muscles during these months, delivering powerful long-period swell generated by intense extratropical storms tracking across the basin. Average wave heights hover between 2.4m and 3.2m, with periods frequently exceeding 12 seconds — the kind of juice that lights up Neminja's southwest-facing sandbars. The swell direction is dominated by W, WNW, and NW, which, while not always optimal, funnel significant energy into the spot. When winds align from the offshore quadrant (NNW, NW, WNW, W) — which occurs roughly 22-25% of the time — conditions can be world-class. However, the flip side is a high frequency of onshore S and SSW winds, often accompanying the same low-pressure systems that bring the swell. Timing is everything; scoring Neminja at its best requires patience and a close eye on the pressure gradients.

Fair Surf Season (April, May, September)

As the planetary wave train begins to relax, the Atlantic still pumps out rideable swell, but with less consistency and size. April and May see average surf heights drop to 1.9-2.4m, with periods around 10-11 seconds — perfect for fun, rippable waves on a good day. The dominant swell shifts slightly towards the NW and WNW, with a growing presence of W and WSW pulses. Wind conditions improve marginally, with offshore wind frequencies reaching 25-29%, especially in September. These transitional months offer a sweet spot for surfers seeking quality waves without the winter crowds or the intense storm-driven conditions. September, in particular, can be a gem as the ocean remains warm and the first autumn lows begin to stir.

Low Surf Season (June - August)

Summer settles in over the Iberian Peninsula, and Neminja feels the lull. Average swell heights bottom out between 1.5m and 1.6m, with periods dipping below 9 seconds — fun for a groveler or a longboard, but lacking the power for serious performance. The dominant swell continues from the NW and WNW, but wave heights rarely exceed the 1.5m range. On the bright side, offshore wind windows from the NNW, NW, and WNW become more consistent, especially during morning hours, with ideal frequencies at 25-27%. Yet even with clean conditions, the lack of significant swell energy means the spot rarely reaches its full potential. It's a time for small-wave experimentation, improvement, and enjoying the long summer days — but don't expect pumping surf.

November: Consistent Winter Build

November continues the ramp-up: average swell height 2.8m, period 11.9 seconds — serious winter swell. The dominant swell directions are WNW (11.0%), NW (10.8%), and NNW (10.4%), with W swell at 5.9% and WSW at 2.2%. The mix favors the optimal directions enough to deliver many good sessions. Wind remains a factor: ideal offshore wind frequency is 24%. Onshore winds from S (9.8%), SSW (9.6%), and SW (7.5%) are still prevalent, but the increasing intensity of storms means more frequent and stronger wind shifts. November is a month of dynamic conditions — you can get huge swell and howling onshore winds one day, followed by glassy offshore conditions and perfect waves the next. It pays to stay flexible and monitor the forecasts closely.
