How hot is merida really?
 

My husband and I will be flying into Cancun, driving to Merida and staying at Hacienda San Jose for 3 days and Casa Esperanza for 2. Then we will be driving to Isla Holbox and staying at Mawimbi for 3 days. Then back to Cancun and home.
My question is: How hot is it going to be in June? Is it Bangcock in May hot or hotter? We love adventure, but I would like to be mentally prepared for an inferno!
