Top Summer Themes of 2025

Getting people out of the house in 2025 isn’t as easy as it once was. Today’s guests need more than the promise of a snack and small talk. They’re looking for immersive experiences, memorable themes, and, of course, Instagrammable moments.

With that in mind, consider some of the top summer party ideas for 2025.

The Pool Party

A pool party is an instant classic for a reason. When the sun is shining, there’s no better place to be than beside cool water with a cold drink in hand. Add floaties, upbeat music, and a popsicle bar for the ultimate summer vibe. Visit this link for Vivaldi Venues’ tips on planning a pool party.

Backyard BBQ Bash

Very few things scream summer like the smell of sizzling burgers and smoky ribs. This year, you could consider hosting a BBQ party for all your friends and family. It doesn’t have to be basic either. You could include one of many summer party activities to make things exciting. Think lawn games, a karaoke setup, or a movie night. For help with catering, don’t hesitate to reach out to Vivaldi Venues. 

Backyard BBQ Bash

Tropical Luau

One of the most popular outdoor party themes, a luau channels the carefree spirit of island life right into your Los Angeles home. With vibrant leis, flickering tiki torches, and tropical cocktails served in coconuts, your space instantly transforms into a mini Hawaiian escape. It’s almost like going on vacation without ever leaving home.

Mediterranean Soirée

From the beaches of Hawaii to a coastal town in Spain, a Mediterranean soirée brings a certain elegance and charm to your party. Think blue-and-white décor, olive branches, grand centerpieces, and a menu filled with tapas, fresh seafood, and cool white wine.

This outdoor summer party idea is the perfect blend of casual and chic and ideal for those golden-hour photo opportunities.

The Boho-Chic Festival

This summer, you could channel the spirit of Burning Man, without all the dust. To set the vibe, incorporate bold colors into your décor and use plenty of string lights to warm up the space. Top it all off with a dreamy playlist, DIY flower crowns, and street food-style catering for an evening that’s relaxed, Instagrammable, and unforgettable.

The Wine Tasting

From the free-spirited to the sophisticated, a wine tasting can add a touch of class to this summer. To pull off this summer outdoor party, consider partnering with a local wine bar or sommelier to curate the perfect collection. With that said, hosting the event indoors — at a dedicated event venue in Los Angeles, for instance — ensures you won’t have to worry about having enough space, or running out of food.

A Fourth of July Summer

An Independence Day party can be a great time to pay tribute to the country, while also sashaying in the warm summer breeze. To set the theme for the night, consider pairing red, white, and blue decor choices with an all-American menu of burgers, hot dogs, or mac and cheese. Round things off with an apple pie, or a few fireworks, and you could soon earn a reputation for throwing outstanding summer parties.

How to Organize a Summer Party the Right Way

While each of these summer theme parties is guaranteed to bring something fresh to the table, organizing a party requires much more. Just ask any planner how hard it is to find a venue for 150 guests in Glendale that is also fit for summer party activities. Party planning requires time, care, and attention to detail. Consider our tips: 

Plan Your Guest List Early

Start drafting a guest list well in advance and send out all invitations early. Knowing the exact number of attendees helps you plan everything else — from space considerations to food and drinks. It also helps you decide which option to go with from a long list of summer backyard party ideas. No one wants to attend a pool party with only five people for company after all.

Plan Your Guest List Early

Plan for Food and Drinks

There are a few considerations that help you ensure you have enough food and drink at your party. The menu is, of course, critical, as is your choice between full service vs traditional catering.

Moreover, you need to think about your guest list carefully. How many children are invited? Do they have enough options? Do guests have any dietary requirements that you need to take into account? How to calculate catering portions

Answering all these questions and more can be key to pulling off your grand summer party ideas. Alternatively, you could get in touch with our expert catering team, and we’ll do the hard work for you.

Choose and Prepare the Right Venue

Whether you’re opting for an outdoor summer party, considering backyard party themes, or planning an indoor bash, the choice of venue is essential. You need to pick a space that fits your guest count as well as accommodates any summer party activities you have in mind. Whether this takes the form of a public pool or a small venue in Glendale, make sure all bookings and decor are planned well in advance.

Have a Backup Plan

LA summers are warm, with plenty of sunshine. But weather often has a habit of being unpredictable. Make sure your summer event ideas are flexible enough to accommodate last-minute changes. Fortunately, it’s unlikely that you’ll run out of unique summer party themes to choose from.
