Just got back from Isla Mujeres yesterday, and are contemplating a trip back with our two children (7 & 10) in mid to late June. We heard VERY conflicting weather reports from Americans now living there.... anybody here with experience? We already have a hot and humid summer (live near DC), but are hoping for some other thoughts. Want to go during this time b/c of summer vacation from school and the whale shark swim tours. Thanks for any info!
