The weather varies depending on the coast, with hotter, more humid weather on the Caribbean side which also tends to experience more tropical storms and hurricanes during the season, generally between July and October with August and September the peak. Storms, including hurricanes, are also possible on the Baja peninsula during this period which also brings scorching hot, dry weather in the summer. Puerto Vallarta is protected and not right on the open ocean, so chances of being hit by a major storm there are unlikely. The summer storm season does bring the possibility for significant discounts and fewer crowds. Winter weather is mild throughout coastal Mexico and the most popular time to visit. You may be able to avoid the crowds, enjoy pleasant weather, and some discounted rates by visiting from mid-April to early June (outside of spring break), or between November and mid-December.
