Stimpy's seasonal overview

Best Surf Season (October - March)

The heart of the northeast monsoon transforms Stimpy's into a powerful, heavy-wave magnet. From October through March, the North Pacific pumps long-period swell from the NE quadrant directly into this east-northeast-facing beach. Average wave heights surge from 1.1m in October to a peak of 1.7m in January, with periods consistently in the 9.5-10.2s range – solid and punchy. The trade-off is brutal: onshore winds dominate, blowing from the same NE-ENE sector over 85% of the time. Ideal wind windows (SSW-W) are scarce, often dropping to just 1-4% in the deep winter months. Yet, when a high-pressure system slides south and a weak trough brushes the Philippines, offshore westerlies align with a building NE groundswell. Those are the days when Stimpy's truly fires – hollow, 1.5-2.5m plus walls with 10-14s periods. Patrol the charts for those brief synoptic setups.

Fair Surf Season (April - May & September)

During the shoulder months, the northeast monsoon relaxes and the southwest monsoon begins to stir. Swell heights drop to the 0.8-1.1m range, but the quality can actually improve. April and May still see a solid ENE swell component (66.3% and 66.7% respectively) at 1-1.5m, while the wind shifts more southerly. Ideal wind percentages jump to 4% in April and 19% in May – still low, but a noticeable step up from winter. September offers the best compromise of the fair season: average swell 0.8m (often fun-sized 0.5-1.5m from NE and ENE) with a remarkable 53% offshore wind frequency. The wave period creeps back up to 9.5s, giving the small swell extra push. You'll be groveling on a fish or a log, but the conditions will be clean and playful.

Low Surf Season (June - August)

The southwest monsoon dominates the summer months, bringing persistent offshore winds (SSW-W) 30-55% of the time. However, the swell engine is nearly silent. Average wave heights bottom out at 0.7m with periods averaging only 8.4-9.0s – choppy, low, and messy by default. June through August sees the swell direction become more scattered, with ENE and E windswell making up the bulk of the tiny 0.5-1m waves. While the rare tropical depression can spin up a short-period pulse from the south or west, these are directional mismatches for Stimpy's. This is strictly a flat spell, best suited for beginner lessons, longboard cruises, or booking a trip to a more exposed reef. If you absolutely have to surf, dawn patrol with a westerly breeze can produce groomed but micro waves.

Conditions at Stimpy's in April

April: Transition Begins

Average swell height drops to 1.1m with a 9.4s period, signaling the end of the prime swell season. Swell direction is overwhelmingly ENE (66.3%), with a significant portion in the 0.5-1.5m range. The wind field starts to shift: onshore winds (NE-E) still dominate (58.2%), but offshore (SSW-W) doubles to 4% – still low but trending better. April is a month of progressive trade-offs. The waves become smaller and more wind-driven, yet the occasional southerly breeze can clean things up for a few hours. It's a good month for a longboard or a funboard, with walls that are better for carving than hucking. The average period of 9.4s keeps the waves punchy despite the lack of size.
