When the SoCal sun starts cranking up the heat, there’s really only one place to be: California’s Largest Water Park. At Raging Waters Los Angeles, hot days aren’t something to dread. They’re an invitation. With more than 50 rides, slides, and attractions spread across 60 acres in San Dimas, we’ve got every reason to leave the stuffy living room behind and spend the day soaking up summer the right way.
What to Do on a Hot Day in Southern California
Southern California summers don’t mess around. When the thermometer climbs, your usual weekend plans (hiking, theme parks, even the beach) can start to feel less and less like fun. That’s why so many people search for things to do on a hot day in SoCal and land on water-based attractions. Water cools you off faster than shade alone, and a full day of splashing around beats sitting inside watching the AC struggle. So if you’re wondering what to do on a hot day, the answer almost always involves getting wet.
Why Water Parks Are the Ultimate Hot Day Activity
Most hot day activities force you to pick between fun and staying cool. Water parks don’t. Wave pools knock the heat out of you with every set. Lazy rivers let you drift in cool water without lifting a finger. Water slides finish with a big splash that resets your body temperature in seconds. Throw in shaded cabanas, frozen treats, and misting zones, and you get a day where you can chase thrills and stay cool at the same time. That’s a hard combo to beat once the temperature spikes.
Fun Things to Do on a Hot Summer Day at Raging Waters
If you’re hunting for fun things to do on a hot day, we’ve got 60 acres of options. From heart-pounding drops to mellow floats and pint-sized splash zones, here are the top ways to beat the heat at Raging Waters Los Angeles.
Thrill Slides and Splash Zones
If your idea of cooling off involves a little adrenaline, you’re in the right place. Launch yourself down Aqua Rocket, California’s first hydromagnetic water coaster, which rockets four-person rafts uphill at speeds topping 30 mph. Try Bombs Away, where you’ll stand on a trap door before free-falling straight down or looping through an enclosed twist. Race your friends on the eight-lane Ragin’ Racer, brave the pitch-black plunge of Neptune’s Fury, or fly face-first down the 600-foot serpentine slides of High Extreme. Every ride ends with a splash, which is exactly the point.
Relaxing Pools and Lazy Rivers
Not everyone needs to feel their stomach drop to have a good time, and that’s where our slower-paced spots come in. Grab an inner tube and float the quarter-mile Amazon Adventure, a tropical lazy river that pulls you gently past palm trees and waterfalls. Stake out a spot at Wave Cove and let the three-foot waves roll in every 12 minutes. Or post up on our sandy beach with a cold drink and let the sun (and the kids) wear themselves out. For maximum relaxation, book a private cabana with shaded seating, lounge chairs, and bottle service that make you feel like an LA celebrity for the day.
Kid-Friendly Water Play Areas
Little ones need a hot-weather escape too, and Raging Waters has two whole zones built just for them. Kids’ Kingdom and Splash Island are packed with interactive splash features, smaller-scale slides, tipping buckets, and shallow water play areas. It’s the same splashy energy as the big rides, sized just right for younger guests. Parents get a break, kids get worn out, and the lifeguards keep a close eye on everyone.
Tips for Staying Cool and Avoiding Sunburn
A few quick pointers will keep your crew comfortable from open to close:
- Hydrate early and often. Refill stations are scattered throughout the park. Sip all day, not just when you feel thirsty.
- Sunscreen, then sunscreen again. Apply a water-resistant SPF 30 or higher before you arrive, and reapply every two hours (more often after slides and swimming).
- Take shade breaks. Cabanas, umbrellas, and shaded picnic areas are everywhere. Use them. A 15-minute cool-down beats a sunburn every time.
- Wear the right swimwear. Skip anything with metal rivets or buckles, since they aren’t allowed on most slides. A rashguard adds extra sun protection.
- Pack water shoes. Pavement gets hot. Water shoes save your feet and stay on better than flip-flops.
