Llorente seasonal overview
Best Surf Season (October - November)
As the northeast monsoon begins to weaken and the first distant storms from the North Pacific send pulses of long-period swell toward the Philippine coast, October and November deliver the best all-around conditions at Llorente. Average wave heights hover in the 1.1-1.5m range with periods often pushing into the 10-second zone, offering rippable waves on a consistent basis. More importantly, the trade winds that plague the winter months start to slacken, and the offshore flow from the SSW to W quadrants becomes more frequent — especially in October, when ideal wind occurs over 35% of the time. This is the sweet spot when you can score clean, punchy surf without the constant onshore battle.
Fair Surf Season (December - March)
Winter delivers the biggest swell of the year at Llorente. From December through March, average wave heights range from 1.5m to 1.8m, with periods in the 9-10 second range and occasional long-period pulses exceeding 12 seconds. The dominant swell direction is ENE to NE, right in the optimal window for the beach's Ost-Nord-Ost orientation. However, the northeast monsoon is in full swing, and onshore winds from the NNE to E blow relentlessly, ruining wave quality more than 95% of the time. Opportunities do arise when a weak high-pressure system stalls or a tropical depression passes to the south, allowing brief windows of offshore SSW to W winds. These are the days to watch — when the combination of heavy, powerful swell and glassy conditions can produce pumping, heavy waves in the 1.5-2.5m range.
Low Surf Season (April - September)
The summer months bring a dramatic shift in the surf regime. The northeast monsoon collapses, and the southwest monsoon (Habagat) takes over. While the wind becomes much more favorable — ideal offshore flow from the SSW to W quadrants peaks at over 60% in August and September — the swell energy plummets. Average wave heights drop to 0.7-0.9m, with periods averaging 8.6-9.7 seconds. The dominant swell direction rotates to more from the E and ESE, which is outside the optimal window. Most days are characterized by small, groveling surf with occasional fun-sized waves when distant typhoons produce long-period pulses. The best bets during this lean season are early morning sessions when seabreezes are light, or tracking tropical cyclones that can deliver brief, punchy swells from the NE quadrant before the wind shifts onshore.

September: Sweet Spot of Clean and Modest Swell
September offers arguably the best chance of scoring clean surf with decent size. The average swell height rises slightly to 0.8m, but the period jumps to 10.1s — the highest of the year. Swell direction becomes more northerly, with NE accounting for 26% and ENE 40%, meaning more energy from the optimal quadrant. Offshore winds from the SSW-W blow 64% of the time, often light. That means many days you'll see clean, waist-to-chest-high waves with long-period lines wrapping in. It's not the biggest month, but when a typhoon churns in the Philippine Sea, the swell can easily reach 1.5-2m with those glassy westerly breezes. September is the sleeper month at Llorente — consistent, clean, and often underestimated.
