Tips

Stick your martini glasses in the freezer for 10 to 15 minutes before pouring. A frosted glass keeps the drink ice-cold until the last sip.
If making watermelon juice from scratch, cube fresh seedless watermelon, blitz it in a blender (paid link) for 20 seconds, and pour it through a fine-mesh strainer to catch any pulp.
Add a squeeze of fresh lime juice (about ¼ oz) to give the sweet melon and guava a tart, zesty punch.
Swap regular vodka for watermelon, cherry, citrus, or coconut vodka to layer in extra dimension.
Make it spicy by rubbing the rim of the martini glass with a lime wedge and dip it into chili-lime seasoning (Tajín) for a spicy-sweet contrast.
Add some herbs by muddling 2 fresh basil or mint leaves in the bottom of the shaker before adding the liquids and ice.
Need a bigger batch? Multiply the watermelon juice, vodka, guava nectar, and agave by the number of guests and stir in a glass pitcher (paid link). Keep chilled in the fridge for up to 24 hours. Shake individual servings over fresh ice right before serving.

If you are looking for a great (and refreshing) drink on the weekend, give this Tropical Watermelon Martini a shot, and you will enjoy it.
