Looking for weather similar to Hawaii’s? Puerto Vallarta is located on the same latitude as the Hawaiian Islands, providing it with a year-round tropical climate and plentiful sunshine.
The busy travel season in Puerto Vallarta is November through March for good reason. The daytime temperature is usually in the 80s and evenings drop into the 60s. Rain is rare during this time of year.
Puerto Vallarta’s wet season usually begins in mid-June and lasts until mid-October. During that four-month period, the city receives nearly 50 inches of rain, almost the total for the entire year. September is usually the wettest month, receiving nearly 15 inches. July and August are not far behind. Although it rains almost every other night during the rainy season, summer tropical storms usually wait until early evening before putting on their spectacular display of thunder and lightning over the Bay of Banderas. Expect very heavy rain in a short period of time, usually five hours or less. During the remainder of the year less than 10 inches of rain falls.
Beginning in May, the humidity begins to creep up until it becomes quite uncomfortable for many people, reaching over 80 percent by July. Summer heat typically ranges from the upper 80s to the mid-90s, so you will probably want to spend much of your time in air conditioning or on the beach.
And, bring plenty of sunscreen. This international beach resort city averages well over 300 days of sunshine each year. If you love the water, you can enjoy it all year long. The Bay of Banderas is usually around 75 F in January and warms to 86 F by early fall.
Puerto Vallarta also is no stranger to severe weather events. Hurricanes that develop off the southwest coast of Mexico make their way up the Pacific coast from June through October but rarely damage the city or other communities that ring the Bay of Banderas. The southwestern tip of the bay deflects most hurricanes and severe tropical storms. But Hurricane Kenna, the third most powerful hurricane ever to hit the west coast of Mexico, visited Puerto Vallarta in late October 2002 and caused significant damage, primarily from the storm surge that inundated the downtown area. Hurricane Patricia, a Category 5 storm, narrowly missed Puerto Vallarta in 2015. It was the most powerful hurricane ever measured in the Western Hemisphere, with sustained wind speeds up to 200 mph.
