As an add on to your rec, for those in hot weather, remember that water is your friend. Stay hydrated. Wet clothes on skin pull heat away from you (cotton is very good for that). Hot air blowing over water cools down which can be used to help cool things down if the humidity is low.

In terms of a queer thing by queer creators, I shall rec Stars in Their Eyes, written by Jessica Walton and illustrated by Aśka. Absolutely gorgeous short graphic story about a teenager going to a fancon. Description snitched from elsewhere:

Maisie has always dreamed of meeting her hero, Kara Bufano, an amputee actor who plays a kick-arse amputee character in her favourite show. Fancon is big and exciting and exhausting. Then she meets Ollie, a cute volunteer who she has a lot in common with. Could this be the start of something, or will her mum, who doesn’t seem to know what boundaries are, embarrass her before she and Ollie have a chance?
