When is Rainy Season in Mexico?

December marks the beginning of the dry season in most parts of Mexico, as the rainy season typically ends in October or November, depending on the region.

However, it’s important to note that some areas, particularly the Gulf coast and the Caribbean coast, may still experience some rainfall in December. The heavy rainfall and thunderstorms that are common during the rainy season become less frequent during December, as the weather becomes drier and more predictable.

However, it’s important to keep in mind that the weather in Mexico can be unpredictable, and occasional rain showers can still occur. It’s also worth noting that the humidity levels in December can still be high in some regions, which can make the heat feel oppressive.

The best thing to do is to check the weather data or the weather forecast beforehand to make sure you get the most accurate predictions.

Overall, December is considered a good time to travel to Mexico as the weather is generally dry and sunny, providing good conditions for outdoor activities and sightseeing.

So yet another bonus to visiting Mexico in December is that it is VERY unlikely you will have rain during your trip as you are now well into the dry  season!
