Just 22 miles off the coast of Southern California, Catalina Island is a sun-drenched slice of paradise that’s perfect for a summer escape. From crystal-clear waters to charming coastal towns and exhilarating marine life, the island offers a wide range of experiences for every kind of traveler. Whether you’re sailing in from San Diego or planning a quick day trip, summer is the ideal time to explore everything Catalina has to offer.
Why Visit Catalina Island in the Summer
Summer is when Catalina Island truly comes alive. Warmer waters make swimming, snorkeling, and kayaking more enjoyable, while longer daylight hours give you more time to explore. Summer is also when Catalina Island tours are in full swing, offering access to everything from glass-bottom boat rides to rugged inland expeditions.
Beyond the activities, there’s a relaxed, vacation-like vibe throughout Avalon and Two Harbors in the summer. With music echoing from beach bars, fresh seafood served on waterfront patios, and boats bobbing in the harbor, Catalina feels like a Mediterranean escape just off the California coast.
Top Things to Do in Catalina Island During the Summer
From adrenaline-pumping activities to laid-back beach lounging, there are countless things to do on Catalina Island in the summer. Here are some must-try experiences:

Sailing to Catalina Island: What to Expect & What You’ll See
Sailing to Catalina Island offers a unique and unforgettable way to arrive on this island oasis. Departing from ports like San Diego, Dana Point, or Newport Beach, a sailboat trip allows you to soak in the coastline, enjoy the sea breeze, and spot wildlife along the way.
During summer months, you’re likely to see pods of dolphins, seals sunning on buoys, and even migrating whales if you’re lucky. Sailing offers a peaceful, unhurried approach to travel—and makes for a great bonding experience with family or friends. Next Level Sailing offers coastal charters that pair comfort with unforgettable scenery around the San Diego Bay. That said, you can certainly charter the yacht America to take you and your family to Catalina.
Catalina Island Summer Weather
One of the biggest draws to visiting Catalina in the summer is the idyllic Catalina Island weather. From June through September, you can expect daytime highs between 75°F and 85°F, with cooler evenings in the 60s. The water temperature typically ranges from 68°F to 72°F—warm enough for most swimmers without a wetsuit.
The island sees little to no rainfall during summer, making it the ideal time for water sports, outdoor dining, and hiking. Pack light layers, reef-safe sunscreen, and a swimsuit—chances are, you’ll be spending most of your day outdoors.
How Many Days Do You Need on Catalina Island?
If you’re short on time, a Catalina Island day trip is definitely doable—but spending at least two days gives you a chance to explore at a more relaxed pace. A day trip allows you to enjoy the highlights of Avalon, grab lunch by the harbor, and do one or two guided activities.
However, if you want to include snorkeling, hiking, beach time, and perhaps even visit Two Harbors, an overnight stay or weekend trip is ideal. With cozy inns, resorts, and campgrounds available, Catalina makes for a perfect weekend getaway that feels far removed from mainland hustle.
