Honestly, if you're picturing Los Angeles as a permanent, 24/7 loop of "Baywatch" sun and palm trees, you’ve been sold a bit of a Hollywood dream. Don't get me wrong—the weather here is incredible, but it’s a lot more nuanced than just "hot." People constantly ask me, "How is the weather in Los Angeles California?" expecting a simple answer, but the reality depends entirely on whether you're standing on the Santa Monica Pier or hiking behind the Hollywood sign.
Basically, LA is a collection of microclimates. You can literally drop 20 degrees just by driving 15 miles toward the ocean.
Right now, in mid-January 2026, we’re seeing exactly how weird Southern California winters can be. While most of the country is shivering, Los Angeles is sitting pretty with a nighttime temperature of 62°F as of tonight, January 17. It’s cloudy, sure, and there’s a tiny 10% chance of rain, but compare that to a Chicago January. Exactly.
The Myth of the "Eternal Summer"
One of the biggest misconceptions is that it never gets cold. It does. Sorta. In a very "LA way."
Winter in the City of Angels is actually the wet season. If you’re visiting in January or February, you might get a week of absolute crystal-clear blue skies followed by three days of heavy, tropical-feeling downpours. Tonight’s forecast shows a high of 79°F today—practically summer—but it'll dip to a brisk 51°F tonight.
If you walk outside in a t-shirt at 10 PM, you’re going to regret it.

The wind is currently coming from the northeast at 5 mph, which is pretty gentle. But when those Santa Ana winds kick in from the desert, everything changes. The air gets bone-dry, the fire danger spikes, and suddenly it's 85 degrees in November.
Why January 2026 is Looking "Un-Winter-Like"
We’re currently transitioning out of a La Niña cycle. According to the latest NOAA reports, there's a 75% chance we'll hit ENSO-neutral status by March. For you, that means a drier, warmer-than-average start to the year.
Look at the week ahead for Los Angeles:
- Sunday, Jan 18: Pure sun, high of 78°F, low of 52°F.
- Monday, Jan 19: More sun, 76°F.
- Tuesday, Jan 20: Still sunny, 75°F.
It isn't until next weekend that we see a real shift. By Saturday, January 24, we’re looking at a high of only 66°F with a 20% chance of light rain at night. That’s the classic LA winter "dip."
The "June Gloom" is Real
If you’re planning a trip for early summer because you want that "California Sun," be careful. May and June are actually some of the grimmest months for beach weather. Locals call it "May Gray" and "June Gloom."

A thick marine layer—basically a wall of clouds from the Pacific—rolls in and stays until noon or 1 PM. If you’re at the beach, it might never clear up at all. Meanwhile, just 10 miles inland in the San Fernando Valley, it’s 90 degrees and sunny. It’s a bizarre atmospheric tug-of-war.
Breaking Down the Seasons (Simply)
- Spring (March–May): This is the sweet spot. The hills are actually green (briefly), the air is clear after the rains, and the temperatures hover between 65°F and 75°F.
- Summer (July–September): It gets hot. Not "Florida humid" hot, but "dry desert sun" hot. Inland areas like Burbank or Pasadena can easily hit 100°F while Santa Monica stays at 75°F.
- Fall (October–November): My personal favorite. The summer heat lingers, but the crowds are gone. This is often the warmest time of year for the actual beaches.
- Winter (December–February): Mild days, cold nights. Expect rain, but expect it to pass quickly.
What to Actually Pack
You’ve heard it before, but layers are the only way to survive LA weather without looking like a confused tourist.
If you’re heading out for the day, you need a hoodie or a light jacket in the car. The second that sun drops behind the Santa Monica Mountains, the temperature plummet is real. The humidity is currently around 49%, which is comfortable, but it can swing wildly.
Tomorrow (Sunday), the humidity is expected to drop to 34%. That dry air makes the sun feel hotter than it actually is. Wear sunscreen. Seriously. Even if it’s "only" 75 degrees, the UV index in Southern California doesn't play around.
The Air Quality Factor
You can't talk about LA weather without talking about the "S" word: Smog. It’s significantly better than it was in the 80s or 90s, but heatwaves still trap pollutants in the basin. If you have asthma or sensitive lungs, the late summer months (August and September) can be tough.

Rain is actually a blessing here because it "scrubs" the air. The day after a big storm is when you get those iconic photos of the snow-capped San Gabriel Mountains looking like they're right behind the palm trees.
Actionable Tips for Your LA Trip
Don't just check the "Los Angeles" weather on your phone. It usually pulls data from the Downtown (DTLA) station or LAX.
If you're going to Malibu, subtract 5-10 degrees from the DTLA forecast. If you're going to the Valley (Universal Studios), add 5-10 degrees.
Plan your activities by the clock:
- Morning: Great for hiking Griffith Park before the heat peaks.
- Midday: Hit the museums or indoor spots if you're inland, or head to the coast to escape the heat.
- Evening: Sunset at the beach is beautiful, but grab that jacket.
The weather in Los Angeles California is remarkably reliable, but it isn't a monolith. Use the current mild January stretch to explore the outdoor spots—like the Getty or Descanso Gardens—while the UV index is low and the temperatures are in that perfect 70-degree "Goldilocks" zone. Just keep an eye on next Saturday's slight rain chance if you're planning any big outdoor events.
