La Union (San Juan La Union) sää — huhtikuu

Forum posters describe September as one of the wettest months across the Philippines, second only to October on average, with typhoon season adding real variability - a typhoon can bring rain for days, while an ordinary rainy stretch typically means a sharp, short downpour rather than an all-day event. Posters describe a typical 10-day window as mixing a few bright, sunny days with a few genuinely torrential ones, and note forecasts only become reliable a few days out given how quickly conditions shift. Posters describing La Union specifically highlight it as a well-established surf destination with newer resort development, implying the wave conditions tied to this wetter, windier season can actually work in a surfer's favor. Posters generally rate September as genuinely wet and typhoon-prone but still very visitable for La Union with flexible plans, particularly appealing for surf-focused travelers.

Forum posters describe the La Union/Baler surf season as running roughly October through March, placing March near the tail end of the best window rather than deep in the off-season - posters call the weather generally fine for a March trip, though peak conditions (November-February) are technically just behind. La Union is repeatedly named as the Philippines' second-most-popular surf destination, drawing a crowd that skews heavily toward surfers rather than general beachgoers, with decent snorkeling spots nearby as a secondary activity. Wave conditions this time of year are described as generally beginner-friendly, a pattern posters say tends to hold from the December low-season stretch through into early spring.
