Chiapas

Dry Season (November to April): This period is considered the best time to visit Chiapas. The weather is generally drier and cooler, making it ideal for exploring archaeological sites like Palenque, the natural beauty of Sumidero Canyon, and the stunning waterfalls such as Agua Azul and Misol-Ha. This time also aligns with the peak tourist season.

Rainy Season (May to October): The rainy season brings lush greenery and higher chances of rain, particularly from June to September. While it might deter some travelers due to occasional heavy rainfall, it can be a beautiful time to witness the vibrant landscapes and waterfalls in their full glory. Keep in mind that some areas might be more challenging to access due to the rains.

Considering the region's natural attractions and archaeological sites, the dry season (November to April) is generally favored by most visitors due to more predictable weather and better accessibility to tourist sites. However, if you're willing to embrace occasional showers and want to experience Chiapas when it's lush and green, the rainy season can offer a different perspective.
