Traveller notes on La Union in March
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.
Other months in La Union
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.
