Puerto Vallarta really has no hurricane season per se, this is because of its location in the middle of the Banderas Bay that is also surrounded on all sides by mountains, sometimes hurricanes pass through the area and the city is a bit affected by them, but mostly on the sidelines. Now, that doesn’t mean that PV is in some way magically free from hurricanes, as some liked to believe.
In any case, one thing is quite clear, Puerto Vallarta is not a place where you need to worry too much about hurricanes, if you compare it with Cancun, then PV is a walk in the park, Quintana Roo (the state where Cancun is located) has close brushes and direct hits almost every year. The average for direct hits on Cancun, for example, is one every 7 years (ref: HurricaneCity). Vallarta is more like once every 35 or so years :-).
