Some other ideas for the weekend:
Physical Hobbies like exercising, biking, swimming, or maybe taking the bus/train to a new place and walking around there etc
Creative Hobbies like drawing, writing, editing images, making a new kind of meal, or learning to make icecream to fight the heat, singing, listening to or even making music, puzzle games etc
Crafty Hobbies like mentioned above, you can Knit, Crochet, Quilt, Sow, do Origami, or learn how to fold all kinds of paper airplanes (there ate whole books for paper airplanes), you could try carving, be it wood, or soap, or make collages, or maybe sitting down with a puzzle and so much more
With Others you can hang out and watch a movie/show/talk about whatever you like, go Bowling, to a Cafe, picknicks and boardgames, or Tabletop Roleplay Games like D&D and so many others are amazingly fun and there are endless options
On Your Own you can also watch shows and movies as well, read fanfiction or books and listen to audiobooks (found at a local library for free), you can play videogames, or get some cards and play solitaire.
Hope you all can have a good time this upcoming weekend, no matter what you end up doing :)
