Cancun in August?

Basically I want to take my boyfriend on a trip to Cancun. The only time he has ever been on vacation was when he went to Florida as a young boy and to South Dakota (and we live in Minnesota, so that’s not much of a vacation.) I have been to Cancun before, I went in April a few years ago and LOVED it. Best place ever.

Anyways, I wanted to go on this vacation end of May, early June. He wants to go late August. As I been talking to my coworkers and friends about his plan for late August people have been saying things like “Oh it’s going to be HOT” or “Oh it’s not going to be much fun cause it wont be busy and tourist-y”. Things like that.
Now, when I remember going to Cancun in April it was f*cking hot. Is August really going to be way hotter, like unbearable?

Is it not going to be a huge party 24/7? Not that I wouldn’t mind a nice, quiet vacation. I just want to get hammered on a beautiful beach with my boyfriend… and party…

So my question here is what do you think? Have you been to Mexico in August? Is it awful? Should I shoot for May/June or wont it really matter?

Thanks for helping!! XOXO
