When to go

Best time to visit Puerto Vallarta and Bahia de Banderas

Puerto Vallarta and Bahia de Banderas run on a classic Pacific pattern: a drier, cooler season from roughly November to April, and a warmer, wetter season from June to October.

Best overall window

November to April

Dry season, lower humidity, dependable beach days, and comfortable evenings.

Outside that window

Rainy season with afternoon storms and eastern Pacific hurricane risk. Water is warm around 28°C and the bay can still be great in the morning.

Choose your trip style

Start with the overall answer, then switch only when scuba, freedive, snorkel, or topside timing changes the trip in a meaningful way.
