The temperature outside may suggest otherwise, but summer's days are numbered. If you're looking for a way to savor the season while it's still here, head on over to Dairy Queen. According to Thrillist, the fast food chain is offering a selection of tasty buy-one-get-one-free deals on ice cream treats now through September 2.

The easiest way to cool down with a free dessert from Dairy Queen is to download the DQ mobile app. From there, click on the "deals" tab and check out the chain's special offerings for the season, including buy-one-get-one small sundaes and malts and shakes of all sizes.

Buy-one-get-one ice cream is great, but free ice cream is even better. If you're downloading the DQ app for the first time, you get a free Blizzard automatically, no strings attached.

Dairy Queen's seasonal BOGO deals are currently available through the app, and valid at all locations outside of Canada and Texas. And if you can't make it to your local DQ before Labor Day, the restaurant is offering a $4 burger and Blizzard deal and a special pumpkin pie Blizzard flavor to ring in the unofficial start of fall.
