Watermelon margarita floats are a bright and refreshing summer entertaining beverage. The addition of watermelon sorbet turns margaritas into a memorable summer cocktail!

During the summer, there’s nothing quite as refreshing as biting into an icy cold watermelon. Let’s take those fresh, invigorating watermelon notes and add it a classic cocktail.
Frozen Watermelon Margarita
This is the third cocktail float in my summer series. We started with cucumber gin and tonic floats and followed with grapefruit greyhound floats. ย
Closing out the series with watermelon margarita floats!
SUMMER COCKTAIL FLOAT SERIES
I’ve taken this fresh lime margarita and amped the flavors with watermelon juice and watermelon sorbet.
While I think the seeded watermelons are far superior, seedless watermelons do have their shining moments.
Seedless watermelons are perfect for juicing, smoothies, and sorbets.
Not only this cocktail float delicious, it “feels” hydrating. For me, anything with watermelon during summertime is rejuvenating.
Whether you’ll be spending your weekends lounging by the pool or plopped on the couch watching Parks and Recreations marathons (like me), you’ll need this juicy, boozy, and pretty cocktail in hand.
Non-Alcoholic Watermelon Mocktail Float
Float the scoops of watermelon sorbet in Sprite, 7-Up, or ginger ale.
To make the popular Korean watermelon punch, layer together 2 scoops of watermelon sorbet with 1/4 cup milk and 1 cup lemon-lime soda of choice.

I loved the watermelons with the seeds in them! Do you remember the Rugrats episode where Tommy, Phil, and Lil went inside Chuckie because he swallowed a watermelon seed? That was the only time I ever heard that rumor!
I don’t know when I last had a float of any kind. All your float recipes are really making me crave one right now, but especially this watermelon one. I am long overdue for some watermelon in my life too.
