Pool party ideas
for the hottest day of the year.

Pool party ideas for adults

The mistake at most adult pool parties is treating the pool as scenery. Turn it into an arena instead. The inflatable pool olympics is the reliable centrepiece: run a lilo relay, a noodle joust, a breath-holding contest and a deliberately absurd synchronised-swimming routine, each scored out of ten by a panel of whoever is too dry to compete. Medals cut from cardboard and foil cost nothing and are taken surprisingly seriously by grown adults in the water.

Between events, people want to cool down and graze, not sit through a formal meal. Keep drinks in a cooler within arm's reach of the shallow end, and float a tray of snacks so nobody has to climb out.

Pool party food ideas

Poolside food has two rules: no oven, and nothing that spoils in the sun. A grazing board of cured meats, hard cheese, crackers and fruit holds up for hours and needs zero cooking. The five-ingredient snack bar covers anyone who wants something more substantial without turning you into a short-order cook in the heat. Watermelon, frozen grapes and ice lollies are the three cheapest crowd-pleasers there are. The full builds are in party food ideas.

• Keep it cold or keep it dry: anything with mayonnaise or raw egg should stay on ice or stay home.
• One-handed only: people eat with wet fingers, standing up. Skewers, wedges and cups beat anything that needs a knife and fork.
• Hydrate first: for every alcoholic drink, have water and something non-alcoholic just as visible — sun and booze is a fast way to end a party early.

Pool party ideas for kids

A kids pool party is two hours of water games and one non-negotiable rule: an adult is watching the water at all times, with nothing else to do. Beyond that, keep it simple and cheap. Sponge relays, a floating treasure hunt with coins scattered on the pool floor, and the splash events from a backyard olympics will burn every ounce of energy a child has. Keep non-swimmers in the shallow end, count heads often, and end with ice lollies out of the water so everyone dries off before parents arrive.

No pool? No problem.

Almost none of this needs a real swimming pool. A large inflatable pool, two sprinklers, a slip-and-slide made from a tarp and a squirt of washing-up liquid, and a bucket of water balloons will run the same games at a fraction of the price. On a hot enough day, a hose and a paddling pool is a party. For more warm-weather formats, see seasonal & summer party ideas.

Pool party themes

A theme gives guests something to wear and photograph. The dependable summer ones are a tropical luau (leis, fruit, a limbo pole), a neon glow party for after dark once the pool lights come on, or a retro 1980s pool party built entirely around inflatables and a synth playlist. Pick one that survives contact with water — anything requiring dry costumes or careful make-up is fighting the venue.
