Het weer in Vigan in mei

Philippines forum posters are upfront that August sits in the thick of the rainy season nationwide, and Vigan's Ilocos coast gets its share - expect a two-to-three-hour downpour most days rather than an all-day soak. Typhoon season technically runs August through early December, and while the Philippines is spread out enough that one region can be flooding while another stays clear, this stretch of the northern coast is more exposed than the southern Visayas. It's still workable for wandering Vigan's cobblestone heritage streets between showers, just keep plans flexible around the afternoon rain window.

Forum posters place Vigan within the broader December-May window locals consider its most festive and visitor-friendly stretch, with January through March singled out as a particularly easy time weather-wise and less busy than the December and April peaks. Early February specifically is described as a transition point out of the rainy season and into summer, generally good but with the usual caveat that Philippine weather can shift unpredictably regardless of season. For the visit itself, Vigan's 400-year-old Spanish colonial old town (a UNESCO World Heritage site) is called compact enough to see well in about two days.
