Why is the ocean so cold in Los Angeles?
The water along the coast of California is cold for a couple of reasons. First, the California Current brings cold water from Alaska southward along the coast. And second, cold water from the deep ocean comes up to the surface through a process called upwelling.
California's ocean water is pretty cold, even in the summer, and it often catches visitors off guard.
There are two general reasons as to why the water temps are much colder on the West Coast compared to the East Coast. The first reason is because of the California cold current that runs along the coast from Canada to Central America. The second reason is upwelling.
The sun's energy only reaches the surface of the ocean, and the deeper you get—from about 50-60 feet and onward—there's what is known as a “cold pool.” The sun can't penetrate the cold pool, so winter weather water remains in the deep ocean.
In January, 1921, a snowstorm covered the roof of Charlie Chaplin Studios in white and rendered La Brea Avenue a slushy mess. L.A. experienced its lowest temperature on record, 28 degrees, in 1949.
These temperature extremes were measured in downtown Los Angeles and go back to 1921. The lowest temperature recorded there during that period was 28 degrees Fahrenheit (-2 Celsius) on January 4, 1949.
With over 120 kilometers (75 miles) of coastline and over 100 beaches, Los Angeles is the perfect place to get your toes wet. The city features plenty of island, coastal, and inland swimming spots.
Average annual water temperature on the coast in Los Angeles is 62°F, by the seasons: in winter 59°F, in spring 59°F, in summer 66°F, in autumn 65°F. Minimum water temperature (55°F) in Los Angeles it happens in March, maximum (70°F) in August.
You can swim at almost all beaches in Los Angeles. Santa Monica Beach, Mother's Beach, Rat Beach, and Abalone Cove Shoreline Park are especially popular.
San Diego has a marine climate, strongly influenced by cool Pacific Ocean temperatures that annually range from the upper 50s to upper 60s. As the cool ocean air spreads inland it gradually warms, with much higher temperatures in the inland valleys.
Does the California ocean ever get warm?
Ocean Temperatures Along the California Coast in Summer
The Pacific Ocean continues to warm throughout June and July along the entire Californian coast. At most beaches, the water temperature peaks in August and early September.
The reason is a process called upwelling. It's a pretty simple idea. Wind and currents pull the warmer water at the top (warmed by the famous San Diego sunshine of course) away from the beach and that water is replaced by colder water from the bottom of the ocean floor.

Why is Outer Banks water cold? Outer Banks water is cold because southwest winds push warm water up to the surface of the Atlantic Ocean and away from the shore. This flow of wind enables cold water that is below the warm water to move in.
A “supercoolometer”, a device that sounds like it should be used to measure hipsters, has found the coldest seawater on Earth, under Antarctic sea ice.
The sediments and organic material are the main causes of the cloudy water along the CA coast.

These temperature extremes were measured in downtown Los Angeles and go back to 1921. The highest temperature recorded during that time there was 113 degrees Fahrenheit (45 Celsius) on September 27, 2010.
Persistent high pressure shapes many of the world's subtropical deserts. In California, high pressure during the summer steers storms well clear of the state. During these times, the only sources of moisture that can reach Southern California come from occasional monsoonal storms to the southwest.
What is the hottest California has ever been?
Death Valley holds the record for the hottest temperature ever, reaching 56.6°C in July 1913.

Visit Santa Monica Pier and Beach
Opened in 1909, the historic Santa Monica Pier has a lot to offer people of all ages! And the beach is always free to enjoy.
Even though April is likely not quite warm enough to swim in the ocean, you never know with Los Angeles. Definitely pack a swimsuit and a few other beach items—sunscreen, sunglasses, a towel—just in case it's sunny enough to spend a few hours out on the sand.
58°F. Today water temperature in Santa Monica is 58.8°F. Water of this temperature is considered cold enough.
The water temperature in Los Angeles in january is freezing. You won't be able to swim in Los Angeles in january! The water temperature is freezing, reaching as low as 57°F (and only 61°F at best)! Our advice: if you are going to Los Angeles this month, plan to sightsee and forget the beach!
Will Rogers State Beach was the primary filming location of Baywatch. The Baywatch production sites are all over California, but the beach is located on Santa Monica Bay, in the Pacific Palisades suburb of Los Angeles. The Will Rogers State Beach offers facilities for playing volleyball and gymnastic equipment.
Venice City Beach
Venice City Beach is the main beach in LA's Venice District. Besides the neighboring Santa Monica beach, this seafront is considered the safest beach for kids in LA.
Ocean temperatures of around 68 or 69 degrees can be found in August off Los Angeles, Dana Point, Oceanside, Santa Monica and La Jolla. Overall, the ocean along the state's southern coast is at least ten degrees warmer throughout the year than off northern California.
California's climate is changing. Southern California has warmed about three degrees (F) in the last century and all of the state is becoming warmer.
Which is hotter San Diego or LA?

Second, the water beneath those winds grows warmer the farther west you go. (It is the Trade Winds themselves that cause this by pushing Sun-warmed surface waters toward Asia.) The counter current (however it got started) carries some of that warm water back to Hawaii.
What does Earth's rotation have to do with ocean temperatures off San Diego?

According to Climate Central, as of right now, a 100-year flood for the Outer Banks will be nine times more likely to occur by 2050 due to sea level rise. Hallac sees this increase right now.
Alligators prefer to live in freshwater, and the Outer Banks is mainly made up of brackish water. You can view them in the Alligator River National Wildlife Refuge in Eastern North Carolina if you want to see alligators.
Is it colder to live by the sea?
The cooler air over the ocean will flow to the warmer air off the coast, creating what we call a Sea Breeze, thus making it feel a bit cooler when along a waterfront.
The Weddell Sea, Antarctic Peninsula
The Weddell Sea has been claimed by scientists to have the clearest waters of any ocean in the world.
The Indian Ocean has the warmest surface temperature of all the world¹s oceans, as most of it is found in the tropics.

No, California is not going to fall into the ocean. California is firmly planted on the top of the earth's crust in a location where it spans two tectonic plates.
Experts say two key factors chill the sea even when the sun is shining: The cold California Current, which flows south along the coast from the Gulf of Alaska, and a concept called “upwelling.”

West Coast water temperatures are much lower than those along the East Coast. That is true because ocean waters rotate in clockwise fashion.
