Baleal - surf spot statistics

Best Surf Season (October - March)

The North Atlantic flexes its muscles during these months, delivering consistent, powerful swell as the jet stream drives a relentless parade of extratropical cyclones across the basin. Average swell heights hover between 2.5m and 2.8m, with long-period energy (12-13s) that wraps gracefully around the Peniche peninsula to greet Baleal's north-facing breaks. The wind patterns, while still dominated by northerlies, offer a higher percentage of offshore southern quadrants (SSW to SW) during these months—especially in October, where ideal wind conditions peak at 27%. This season is prime time for Baleal, with the potential for pumping, firing waves in the 1.5-2.5m range when a low pressure stalls off the coast and a ridge builds from the south. The NAO index frequently swings negative, amplifying storm tracks and shunting the jet south, which funnels large, clean swell directly into the spot. If you want epic, heavy sessions, this is your window.

Fair Surf Season (April & September)

These transition months bridge the gap between the powerful winter and the sluggish summer. April sees average swell heights drop to 2.1m with a period of 11.2s, while September bounces back slightly to 1.7m and 10.5s. The swell remains predominantly from the NW and NNW—good directions for Baleal—but the energy is less consistent and often mixed with smaller, choppier groundswell. The wind is ideal about 21% of the time, comparable to March, but the lighter pressure gradients mean the northerly onshore flow (N, NNW) is more variable. You'll find fun, rippable waves on the better days, especially when a lingering summer high-pressure system gives way to a weak cold front. It's a fair season—not firing, but reliable enough for good sessions if you time the weather windows.

Low Surf Season (May - August)

Summer settles over the Portuguese coast, and Baleal enters its slow period. The Azores High strengthens, pushing storm tracks north and leaving the region with weak, short-period swell. Average heights drop to 1.5-1.8m, and periods fall below 10s, resulting in choppy, messy conditions for much of the time. The wind is the real culprit here: from June through August, the dominant north-northwest wind blows directly onshore over 60% of the time, with ideal wind percentages plummeting to 11-18%. July is the worst month, with an average height of just 1.5m and a period of 8.6s—groveling territory. The swell that does arrive is mostly windswell from the NNW, which lines up okay but lacks the power to overcome the onshore breeze. On rare occasions, a late-season tropical system or a cut-off low can throw in a fun day, but for the most part, this is a time to explore other spots or enjoy the beach. The waves are small, fun-sized at best, and only for the dedicated.

November: Deep Winter Energy

November settles into the deep winter groove. Average swell height ramps up to 2.5m and period to 12.1s, as storms intensify across the North Atlantic. The swell rose shows a strong NW component (20.6%) along with WNW (13.5%) and NNW (15.9%), plus a pickup in W and SW swell—this indicates a more active and varied storm track. The wind maintains a decent 24% ideal flow, with southerly breezes often accompanying post-frontal ridges. The major difference from October is the increasing prevalence of larger waves: over 1.5m, the distribution is heavily weighted toward the 2-2.5m range, and there's a small but noticeable percentage of XXL sets over 2.5m. November delivers powerful, long-period groundswell with the potential for epic, heavy waves. However, the wind can be fickle; N and NNW combine nearly 25% of the time, so patience is required. When a deep low passes just north of Spain and a high forms over the Azores, Baleal lights up with perfect offshore conditions and some of the best surfing of the year. It's a month for charging.
