Planning an ocean-themed party can be an exciting adventure! From vibrant colors to whimsical sea creatures, the decorations set the stage for a memorable experience. Here’s my personal guide to help you navigate through the sea of options and choose the best decorations for your ocean-themed celebration.
1. Choosing a Color Palette
When I think of the ocean, I envision a stunning blend of blues, greens, and sandy beiges. For my parties, I love incorporating shades of turquoise, aquamarine, and coral to evoke that beachy feel. I recommend selecting a color palette that resonates with the ocean vibe you want to create, and sticking to it throughout your decorations for a cohesive look.
2. Wall Decor
The walls of your party space can be transformed into an underwater paradise! I usually opt for ocean-themed wall decals or murals featuring marine life like fish, starfish, and sea turtles. Another idea I love is using blue streamers or fabric to mimic waves. If I want to add depth, I sometimes hang paper lanterns in the shape of jellyfish or use netting to give an authentic ocean feel.
3. Table Settings
For my table settings, I like to start with a tablecloth in shades of blue or sandy beige. I often use seashells, sand dollars, and starfish as centerpieces. To enhance the ocean theme, I sometimes scatter faux pearls and sand on the table for added flair. Don’t forget themed plates, cups, and napkins featuring marine motifs—these small details can make a big impact!
4. Balloons and Banners
Balloons are a fun and festive addition to any party! I often choose a mix of blue, green, and white balloons to create an ocean feel. Sometimes, I even find balloons shaped like fish or sea creatures to make things more playful. I also love hanging banners that say “Under the Sea” or “Welcome to the Ocean” to set the mood right from the entrance.
5. Party Favors
I always like to send my guests home with a little piece of the ocean! Simple yet delightful party favors can include small seashells, ocean-themed stickers, or even mini beach buckets filled with candy. I also consider giving out themed bags that guests can use to store their treasures from the day.
6. Lighting
To create an enchanting atmosphere, lighting plays a crucial role. I often use blue string lights or lanterns to mimic the glow of the ocean at night. If I’m feeling extra creative, I sometimes use a projector to cast images of waves or underwater scenes on the walls—this adds a magical touch to the party!
7. DIY Touches
If you’re looking to add a personal touch, I love incorporating DIY decorations. For example, I’ve made my own fish cutouts from colorful cardstock to hang from the ceiling. I also enjoy crafting a photo booth backdrop using a blue sheet and adding props like snorkels, beach hats, and inflatable sea creatures for fun photo opportunities.

I often find the best ocean-themed decorations at party supply stores, craft stores, and online retailers. Websites like Amazon, Etsy, and even local party supply shops offer a wide selection of decorations.
