Hi Susan, i don't know if it's lae to answer to your posto but in June the weather it's just such amazing. Cancún it's a place with beach and that's why people just can enjoy from an warm fresh air. Some days could be really hot but at nights there is so freshing. But remember, you'll be near and rounded by see and sometimes there's could be heavy rains so you could be prevented with boots and a sweater...
Any doubt i'll be glad to try to help you.
