It's the Fourth of July. I know from experience it can be a bit overwhelming for someone who's autistic. Fireworks can definitely be overstimulating for people with autism; I would know since I would have my hands over my ears when I was a kid and eventually got better at dealing with them. In this case, having noise cancelling headphones are the best way to go.
With it being a hot summer, the heat can be uncomfortable too. In this situation, water and fans are good things to have around. If you're going to a barbecue tonight and it's overly crowded, just tell the host(s) you need to have a break and go to somewhere quiet to regroup. And if they don't have food you like, you can bring some food that you enjoy. Other than that, just remember to have fun this holiday.
And in my experience, if it's too hot to be barefoot, wear shoes. Simple as that. Have a great Fourth of July everyone!
