If you’re departing Seattle for LA, there’s a good chance the weather has something to do with it, but either way take the opportunity to enjoy LA’s year-around mild and sunny climate. Nobody walks in LA, so take a drive along Highway 1, starting at Manhattan Beach and ending in Malibu, enjoying the beautiful coastline and mansions along the way. If you really need a good walk, stroll down the Hollywood Walk of Fame and try to spot your favorite celebrity’s star, or spend a day on Catalina Island, where you can explore the island on foot or a bike or explore its waters with a snorkel or rented kayak.
On average, daily high temperatures in Los Angeles are only about 8 degrees warmer than in Seattle during the summer, but about 22 degrees warmer than Seattle during the winter, when the Emerald City also gets a good deal more precipitation. So if Seattle's inclement winter weather gets you down, the Big Orange is a nice respite. New visitors to Seattle are often surprised by how small the city is, while visitors to LA can't get over its vastness. While both cities revere personal freedom and welcome visitors from across the globe, Seattle can't match LA's diversity. The City of Angels is a potpourri of human civilization, with countless restaurants, art galleries, neighborhoods, shops and attractions celebrating the world's disparate cultures.
Save money and time using our smart search engine to find the cheapest flights from Seattle to LA, including dozens of non-stop flights at low prices.
