Need to find a list of hot cartoons in June. Help me!!

I've read this post multiple times and I still have no idea what exactly is being requested. I assume you're asking for cartoons having to do with the summer heat?

---

Sing or Swim (1948) 
Swimmin' Hole (2017) 
Linc or Swim (2016) 
Beach Peach (1950) 

Some other recommendations could also include, but not limited to:
Sahara Hare (1955), the first short to come from an reopened WB Cartoon Studios
The Beach Nut (1944), Wally Walrus' debut cartune.
Muscle Tussle (1953), an underrated Daffy Duck cartoon directed by McKimson
Snow Place Like Home (1949), has very little to do with the summer hear, but important in mentioning since this short is pretty good
Salt Water Tabby (1947) An terrific Tom and Jerry cartoon that perfectly captures the summer vibe at the beach, made even better with the trademark violence and slapstick that Tom and Jerry are behemothly known for.

Those are just my suggestions, there's probably more, but feel free to search to your heart's content.

If this is really what you're look for, I should also recommend the 1947 Disney cartoon Crazy with the Heat 

Well, there's "Bee on the Beach" with Donald and Spike the Bee.
