Here is an easy way to stay hydrated, and the kids will love it, too! Step-by-step instructions on how to make watermelon juice.

I don’t know about you, but we consume massive quantities of watermelon during the summer months. I love that it is so kid-friendly and easy to share with friends. It is also packed with water, so it keeps us all hydrated while we are sweating it out in the heat.
August 3rd is National Drink Watermelon Day and I am going to share with you my family’s favorite way to beat the heat.
I have been using watermelon juice in cocktails (like my watermelon shooters with olive oil). My kids started getting upset because the pitcher of watermelon juice in the fridge was typically spike with vodka – oops!
Recipe highlights
- Simple: This recipe makes watermelon juice without any added sugar or anything else. You control what goes into it. And like my homemade grape juice, no juicer is needed!
- Healthy: Watermelon is 92% water, so the average watermelon can produce quite a pitcherful of juice. Watermelons are an excellent level of vitamin C (25%), vitamin A (30%) and vitamin B6 (6%). These vitamins boost eye health and the immune system.
- Texture: I pass the processed juice thru a fine mesh sieve so that you get a perfectly smooth juice, especially for your picky eaters.
- Flavor: My kids seem to prefer drinking their watermelon than chewing it! This is especially good for melons that are more juice than flesh or have mild flavor.

Step-by-step directions
- Cut the watermelon. You need to cut your watermelon into 1-inch chunks. This watermelon knife is super handy in slicing up watermelon FAST. The holes on the knife keep it from sticking to the melon while cutting it.
- Add to blender. Stuff your watermelon chunks into a blender – and I mean STUFF IT. Don’t be shy. Shove those pieces way down. Because when you start blending, you want it to purée quickly. Add a little water if you have troubles.
- Blend until smooth.Turn the blender on high and go, Go, GO! Blend until all of the chunks and pieces are puréed and your mixture is smooth.
- Strain it. Pass your purée through a fine mesh strainer and use a rubber spatula to press everything through. Now, if you like it thick and your watermelon is seedless, you can slurp it up at this stage. But I like to strain out the seeds and pulp for a more juice-like consistency. This step is necessary for picky kids who don’t like the pulp.
- Chill. I usually don’t serve my watermelon juice until it has been refrigerated for a few hours. We like it nice and cold. After you pour it in a pitcher, make sure you seal the top with a lid or plastic wrap. It should be cold after 3 hours in the refrigerator.
Recipe tips and FAQs
For me, an 10.5-pound seedless watermelon will produce about 3-quarts of juice, once strained. You can serve the juice as is or freeze them in Dixie Cups or popsicle molds to make fruity popsicles. Either way, your family will hydrate and love every minute of it.

Storing/Freezing Instructions
TO STORE: Store watermelon juice in an airtight container and refrigerate for 3-4 days.
TO FREEZE: You can also freeze the juice. Transfer popsicle molds or an ice cube tray and freeze until solid. Transfer ice cubes into a freezer safe bag or container and freeze for up to 4 months.
Yes you can! Just chop the watermelon into chunks and remove any seeds. Then place the chunks in your juicer. The juice will be extract and the pulp will be filtered out.

How can I preserve watermelon juice for long shelf life in a glass bottle .
It should last about a week in the refrigerator in a sealed bottle. Unfortunately it is a perishable item and won’t last longer than that.
really good for a summer party with a shot of vodka!!!
Thanks for sharing, this was very tasty
So glad you liked it! You are very welcome.
I have a juicer can I do this in it?
From what I read online, yes, you can use a juicer to juice a watermelon.
Hi Laura,
I am in total agreement, watermelon juice is fantastic and so refreshing!
May i add that it’s also fantastic to add cucumber and mint when juicing. Will give the juice an even more refreshing after taste. Perfect for summer 🙂
Since I’m half-Persian, cucumber and mint is a combination we love! Great idea, Joana!
Looks fabulous.. I am already feeling thirsty.. Can I have a glass too please??
Sorry, my kids drank it all up! Enjoy!
watermelon is definitely my favourite juice flavour EVER. so craving a glass right now!
I’m always guilty of not drinking enough water but nobody could call me guilty for not eating enough watermelon. I love it! In chunks or in the glass. 🙂
Watermelon juice is COOL! Your knife is cool too. 🙂
