Watermelon-Themed Birthday Party - A Fresh and Fun Celebration

Updated: Jul 24, 2023

Summer is the perfect season for birthday parties, and what better way to celebrate the occasion than with a watermelon-themed bash! This juicy fruit is not only refreshing and delicious, but it is also the perfect symbol of the warm weather and carefree spirit that summer brings. Whether hosting a birthday party, a summer barbecue, or just a fun get-together with friends, Metro-Events has covered everything you need to make your watermelon party successful.

Watermelon themed birthday party


First, let's start with the invitations. I have digital, printable invitations available on my Etsy shop, Corjl. The editing program used to edit these invitations has partnered with Prints of Love for printing services, so you can be sure my invitations will look great when printed. I also have printed and digital invitations available in my Zazzle shop.


Get your guests in the watermelon mood by sending out fun and creative watermelon-themed invitations. If you want to make your invitations extra unique, you can incorporate the following:

  1. Watermelon Stickers to seal the envelopes

  2. An envelope liner that is designed with watermelons

  3. Custom watermelon envelopes

I have all of these items available in my Zazzle shop!


Once your invitations are sent out, it's time to start thinking about party favors and decorations.

To make your decorations stand out and be memorable, choose a color scheme that matches the theme of your party. When it comes to decorations, the possibilities are endless with a watermelon theme. You can use actual watermelons as centerpieces or carve them into fun shapes and use them as vases for flowers. Create a fruity atmosphere with custom signs I have created available in both my Etsy and Zazzle shops.


Create the perfect watermelon photo booth using custom decorations from our Zazzle shop.

First, start with a custom watermelon backdrop. Our Zazzle shop offers a range of designs, so you can pick one that matches your party theme perfectly. Hang it on a blank wall or use a photo booth stand to create a freestanding backdrop.

Next, add some custom banners to the photo booth. Our Zazzle shop has a variety of watermelon-themed banners that you can customize with your text. Hang them across the top of the backdrop or along the sides of the photo booth to add some extra flair.

Finally, remember the pendants! Our Zazzle shop offers a range of watermelon-themed pendants that you can use to decorate the photo booth. Hang them from the ceiling or attach them to the backdrop to create a fun, festive atmosphere.

With these custom decorations from our Zazzle shop, your watermelon-themed photo booth will surely be a hit at your next birthday party!


Watermelon Food Table

If you're planning a watermelon-themed party, you'll want to create a fun and festive atmosphere for your guests. A great way to do this is by decorating your food table with items from Metro-Events on Zazzle.

Start by covering your table with a tablecloth and/or a table runner; I have created both to coordinate with this watermelon theme. Then, place a large watermelon in the center of the table as a centerpiece.

Next, incorporate the watermelon-themed items you've purchased from Metro-Events on Zazzle. Use the kitchen towels to wrap around the handles of pitchers filled with refreshing watermelon drinks. The paper plates can be stacked near the food area, featuring a fun design of watermelon slices. The paper cups can be filled with watermelon-flavored juice or soda. The paper napkins can be folded neatly and placed next to the plates, featuring a matching watermelon pattern. Finally, use the paper coasters to set under glasses or cups to prevent water stains on your table.

For an extra touch, add some watermelon balloons or cutouts around the party area to create a cohesive watermelon theme.

With these simple decorations, your guests will have a "juicy" time at your watermelon-themed party!


Watermelon Cupcakes - Who doesn't love a good cupcake? Make your watermelon-themed birthday party even sweeter with these delicious watermelon cupcakes. You only need some vanilla or lemon cupcakes, green and pink frosting, and some watermelon candies to create the perfect watermelon look. Top them off with custom cupcake toppers available in my Etsy shop.

Watermelon Cookies

Everyone will love this fun and easy treat. I have some that you available in my Zazzle shop that you can purchase already decorated, or you can make your own. make sugar cookies and frost them with green and pink frosting to create the look of a watermelon slice, and you can also add some black frosting for the seeds.

Watermelon Cake Pops - Try making watermelon cake pops for a fun twist on a classic treat. Bake a cake, crumble it up, mix it with frosting, roll it into balls, and dip it in pink candy melts. Add some green and black decorating icing for the watermelon rind and seeds.

Create adorable watermelon-shaped slices using the watermelon-shaped cookie cutters offered by Oriental Trading Company.

Watermelon Sorbet

Watermelon Sorbet Ingredients:

  • 4 cups of cubed watermelon (seeds removed)

  • 1/2 cup of sugar

  • 1/4 cup of water

  • 1/4 cup of freshly squeezed lime juice


  1. In a small saucepan, combine the sugar and water. Heat over medium-high heat, stirring frequently, until the sugar dissolves completely. Remove from heat and let cool to room temperature.

  2. In a blender or food processor, puree the watermelon cubes until smooth.

  3. Add the cooled sugar syrup and lime juice to the watermelon puree, and blend until thoroughly combined.

  4. Pour the mixture into a large, shallow container and freeze for 3-4 hours, stirring every 30-45 minutes with a fork or whisk to prevent ice crystals from forming.

  5. Once the sorbet is fully frozen and has a smooth consistency, serve and enjoy! You can garnish with fresh mint leaves or additional watermelon cubes if desired.

Note: If you have an ice cream maker, you can also use it to make the sorbet. Pour the mixture into the machine and churn according to the manufacturer's instructions.

2. Seed spitting contests: A summer favorite and enjoyable activity at watermelon-themed parties.

  • Gather the necessary materials: You will need a ripe watermelon, ample outdoor space, and some willing participants.

  • Cut the watermelon into slices: Cut it into pieces large enough to hold a decent number of seeds but not so large that they are challenging to handle.

  • Eat the watermelon: Before the contest begins, everyone should have the opportunity to eat as much watermelon as they want. This will allow them to practice spitting seeds and get a feel for how far they can go.

  • Establish the rules: Determine how far participants should stand from the starting line and whether they can take running starts. Decide how many seeds each person will spit on and how the winner will be determined.

  • Begin the contest: Have each person take turns standing at the starting line and spitting their seeds as far as possible. Measure the distance each source travels and keep track of the scores.

  • Declare a winner: After all, participants have had a chance to spit out their seeds, add up the scores and declare a winner.

  • Have a prize: It can be a simple prize like a watermelon or a gift card, or just bragging rights, but having a prize can make the contest more exciting and motivate people to try their best.

3. Watermelon Piñata: Fill a watermelon-shaped piñata with candy and toys, and let the kids take turns trying to break it open. This fun and playful activity will get everyone involved in the party.

Prepare the Watermelon Piñata Fill the Piñata with Summer Treats. Fill the watermelon piñata with anything you want, but we suggest filling it with summer treats like candy and fruit snacks. You can also add some small toys for children to play with after they break open their piñatas!

  • At Oriental Trading, a delightful assortment of watermelon candy is available, perfect for filling up your piñata. These sweet treats would be a great addition to your themed party, adding a touch of fruity fun to the festivities.

Hang Up High. Make sure you hang up your watermelon piñata high enough so everyone can reach it easily when your guests are ready to smash it open! It doesn't have to be too high, though--just enough so that no one gets hurt when they throw their first punch at this fun party activity!

Decide how the winner will be determined (for example, the first person to finish all their slices or the person who completes the most in a set amount of time).

  • Begin the race: Have all participants sit at a table or stand at a starting line with their watermelon slices in front of them. Everyone should eat their watermelon as quickly as possible when the race begins.
