The heat in South Texas is straight up disrespectful, especially during the summer. If you live in San Antonio, you get a lovely mix of scorching temps and thick humidity from May through September.

That's why we rounded up 17 water activities in and around the Alamo City — including some free options — to help you stay cool in the pool.
