Watermelon Margaritas Recipe

This is the time most people start to think of Fall (hello, August), but for us, our melons are just getting ripe in the garden. I notice cans of pumpkin in people’s grocery carts, but we’re over here with melons stacked on our counter. My birthday is in late September, and that is when I choose to start embracing pumpkin. August has always been, and will always be, for the watermelons!

While I’m fairly confident my kids could devour an entire melon in a day, I have to limit the watermelon consumption after 2pm, if you know what I mean. I don’t like to start my mornings washing sheets–now you know what I mean, hah!

Cocktails for two

However, when the kids go to bed, we love to make a batch of watermelon margaritas for the adults! I usually make the simple syrup earlier in the day so it can chill. Simple syrup is just equal parts sugar and water, boiled briefly to dissolve the sugar, and then cooled. We use simple syrup in cocktails because granulated sugar doesn’t dissolve in cold liquids. While honey and maple syrup are convenient, they impart a taste in the final cocktail, in my opinion. However, if you want to skip the simple syrup, reach for agave and never look back!

Choose whatever kind of tequila you like–we reach for a local one, if possible. I like a white clear tequila so that it doesn’t interfere with the melon flavors. I’m trying so hard to warm up to mezcal, but unfortunately, I just don’t love the smokiness. My husband loves it, though!

This watermelon margarita recipe makes enough for 2 margaritas, but feel free to double or triple it for a crowd.

how to make fresh watermelon margaritas

For frozen watermelon margaritas:

If you would like a frozen watermelon margarita, place the watermelon cubes in the freezer for a few hours beforehand! Then, when you’re blending, make sure everything else is super cold (including the tequila), and blend just until things come together. A handful of ice is great added at the end, if you like them super slushy!

Speaking of slushy, have you seen my peach jalapeño margaritas? They’re super cold and slushy! And if frozen cocktails are your thing, don’t miss my peach wine slushies, my rosé wine slushies.

My personal favorite cocktail is my sangria swirled margaritas, though they take some planning ahead of time.

For more tequila love, don’t miss my hibiscus margarita popsicles!

easy watermelon margaritas

One morning, after making these the night before, my daughter saw the leftover watermelon juice in the fridge and asked if she could try it. I made her a virgin watermelon margarita recipe by leaving out the tequila, of course! She thought the salty rim was so special!

Watermelon margaritas recipe for two. Can double or triple.

Prep Time 10 minutes
Cook Time 5 minutes
Total Time 15 minutes


  • 1/3 cup granulated sugar
  • 1/3 cup water
  • 2 cups fresh cold watermelon chunks (1-2" cubes)
  • 2 limes, juiced (plus extra for garnish)
  • 2 shots, tequila
  • coarse salt, for glass rims (optional)


  1. First, combine the water and sugar in a small saucepan, and whisk to dissolve. Bring to a simmer to dissolve all of the sugar, and then then turn off the heat. Whisk it very well, and then pour into a container and chill in the fridge.*
  2. In a blender, add the cold watermelon chunks and juice of the 2 limes. Blend to puree.
  3. Strain the watermelon juice mixture into a jar, and place in the fridge until you're ready to make a cocktail.
  4. To make a watermelon margarita: If you like your margaritas with salt, rim the edge of the glass with a lime wedge and dunk in salt before proceeding. Pour half of the watermelon juice into a small cocktail glass, add half of the simple syrup mixture, and one shot of tequila. Add ice, stir to blend and serve with an extra lime. Repeat with all remaining ingredients to make second margarita and serve.


*Simple syrup keeps for a month in the fridge--make extra to have on hand for all of your favorite cocktails!
