There are very few locations where the word “perfect” comes into the vocabulary unquestioned when talking about the weather, but Puerto Vallarta comes close by most people’s standards of a beach vacation destination. What the majority of visitors are looking for is sunshine, and you certainly get plenty of that in Puerto Vallarta thanks to an average of over 325 sunny days per year, according to statistics.
Temperatures may well soar during summer and the humidity is such that you can save on moisturizer, but it seldom gets much hotter than 91ºF (33ºC) which is actually still quite bearable if you are lounging by a pool or splashing around in the ocean. The reality of summer temperatures is a little lower with averages around 88ºF (31ºC) and lows of 77ºF (25ºC). It is also during the summer that the rains come, so there is always a refreshing shower. Winter temperatures are probably what most people consider the most ideal ranging from around 82ºF (28ºC) to 61ºF (16ºC) at night. In comparison to a North American winter, these temperatures are idyllic.
Rain rarely spoils your vacation in Puerto Vallarta, primarily because it tends to rain for a few hours in the afternoon or at night, so it is quite easy to plan your day around when it is going to rain. You can see the clouds forming and are able to calculate how much time you have left on the beach or by the pool. Likewise, there is a distinct rainy season which runs from June through October, so if you want to make sure you totally avoid rain, you can make your arrangements accordingly. It is worth mentioning that an electrical storm viewed from the comfort of a Garza Blanca unit, is pretty spectacular and an experience you won’t want to miss.
Finally, hurricanes are frequently a concern when booking a vacation. Puerto Vallarta is pretty fortunate to have very little threat from hurricanes, although it is possible that one could enter the bay. Because of the way Banderas Bay is formed geographically, it is not very common for Puerto Vallarta to suffer a direct hit from a hurricane, but rather enjoys the rain and winds from the tails of storms out in the Pacific.
