Watermelon Cucumber Cooler
This watermelon cucumber cooler is a light, slightly sweet and incredibly refreshing summer drink. Fresh watermelon and cucumber get blended until smooth, then stirred with lime juice, honey and cold water or coconut water and poured over crushed ice. This watermelon cooler takes about 15 minutes and makes enough for a crowd.
It is my favorite pool day and BBQ drink, with or without a splash of tequila. Pair it with my Watermelon Cucumber Feta Salad with Honey-Lime Vinaigrette for a full watermelon moment.

Carly’s Expert Tips
- Chill the watermelon first for the coldest, most refreshing drink.
- Dissolve the honey by stirring it into a little warm water if it clumps.
- Taste and adjust the honey and lime, since watermelon sweetness varies.
- Strain for parties. It makes the drink smoother and prettier in glasses.
Make It Your Own
- Cocktail: Add tequila, rum or vodka for a boozy version.
- Tropical: Use coconut water instead of plain water.
- Sparkling: Top each glass with sparkling water.
- Spicy: Add a slice of jalapeño or a Tajín rim.
Make-Ahead and Meal Prep: Make the cooler up to 1 day ahead and keep it in a covered pitcher in the fridge. Stir before serving since it separates as it sits.
