Some say that San Jose del Cabo has the perfect weather - and that's true. Most of the year, you will have sunny skies and cool breezy nights. Much like the summer weather that we are all used to. It does get warmer, and more humid in the summer months, leading up to September which is hurricane season. The heat and humidity are high, and the risk of tropical storms means that you will get many cloudy, and even rainy days in September. The weather breaks mid October and then it's back to beautiful weather once again.
