Phú Yên in February

March through August gives you the best weather, with temperatures hovering around 28-32°C and minimal rain. But here's the insider tip - April and May are perfect. The beaches are empty, accommodation prices haven't peaked, and the sea is calm enough for swimming. Avoid September through November unless you enjoy dramatic storms and flooding. December through February can be surprisingly cool and windy - not ideal for beach lounging but great for exploring inland attractions like the Da Rang grape valley. The rainy season from September to December brings spectacular waterfalls but also makes coastal roads dangerous. If you're planning to visit the famous Ghenh Da Dia rock formations, low tide in the early morning gives you the best access and photos.
