Not knowing what attractions are near you make this a bit difficult. Do not post where you live either. If you are allowed to use public transportation, perhaps you could visit a local zoo, a botanical garden, an aquarium or the planetarium. You probably would have to ask your parent for the cost of admission unless you have your own money. Many of these places have out door area where you could bring a picnic lunch and eat. You will have to check the amenities at these great spots out.

If you have bicycles you could go for bicycle ride and explore your neighborhood. Pack that picnic lunch and eat it in the park, if the park allows food.

Swimming

Window shopping at the mall (this is especially good if you have some money saved up and you want to see what there is to buy without blowing the money OR if it's close to your birthday so you can pick out some gifts/what to buy with birthday money)

Ride bikes around your neighbourhood

A different park than usual?

Café with tables outside (get an iced coffee or something)

Ice cream parlour and then walk around a open air mall or something...

Make a slip and slide. I do one every summer. All you need is large amount of plastic. (I buy two 20 ft sheets at walmart for about 10 bucks in the section where they sell supplies to paint your house) a few bottles orf cheap baby wash or oil (so the soap doesn't burn your eyes) i get mine from the dollar store to save money. The amount is up to you. Spread out the plastic. Add water and soap. Instant fun for ours. Plus the baby oil will make you soft and help with a tan!!

Go for a swim.

If you live near a local public pool, they don't charge much
