So, you’re thinking about heading to the Southland. Maybe you're moving here. Maybe you’re just visiting. But you keep hearing the same thing: "It’s always 72 and sunny in LA."
Honestly? That’s kinda a lie.
If you want to know how hot is it in Los Angeles, the answer isn't a single number. It’s a mess of microclimates, desert winds, and a sun that feels like it’s personally trying to cook you from the inside out. LA is a city where you can be shivering in a foggy 62-degree morning at the Santa Monica Pier and then driving 20 minutes inland to Northridge, where it’s a blistering 104 degrees.
It’s weird.
The Reality of the Los Angeles Heat Map
Most people look at the "average" temperature for Los Angeles and see something like 75 degrees for August. Don't believe it. That average is heavily skewed by the Pacific Ocean.
In reality, LA is divided by mountains and distance from the water.
Take a typical September day. In Malibu, you’ve got that nice, salty breeze keeping things at a crisp 74. You feel great. But go over the Sepulveda Pass into the San Fernando Valley—places like Van Nuys or Woodland Hills—and you’re hitting 105. Sometimes 110. Just last year, in late 2025, we saw record-breaking spikes where the Inland Empire and the Valleys stayed above 100 for days on end.
The sun here is different, too. Because the air is generally dry, there’s nothing to block the UV rays. It doesn’t just feel hot; it feels stinging. If you're standing in the sun, you're roasting. Move three feet into the shade of a palm tree? It’s suddenly 15 degrees cooler.
That’s the "dry heat" everyone talks about.
Why the Santa Ana Winds Change Everything
Usually, the wind blows from the ocean to the land. It’s cool. It’s moist. It’s the "marine layer" that locals call June Gloom.
But then the Santa Anas hit.
These winds come from the high desert to the east. As the air drops down the mountains toward the coast, it compresses. Physics 101: compressed air gets hot. Really hot. And dry as a bone. When the Santa Anas are blowing—usually in the fall or even random weeks in January—the humidity can drop to 5%. Your skin starts to crack, your hair gets static-y, and suddenly it's 90 degrees in the middle of winter.

We actually just had a "Winter Heat Wave" in mid-January 2026 where Downtown LA hit the low 80s while the rest of the country was digging out of snow. It sounds nice until you realize the fire risk that comes with it.
Seasonal Breakdown: When Does It Actually Get Bad?
If you're planning a trip and asking how hot is it in Los Angeles during a specific month, here is the raw truth from someone who lives here:
- January - March: Mostly gorgeous. Highs in the 60s or 70s. You’ll get the occasional rainstorm that shuts down the 405 because nobody knows how to drive in water, but otherwise, it's sweater weather.
- April - June: This is the "Gloom" phase. Gray skies until 2:00 PM. It’s not "hot" yet, but it’s muggy-ish and depressing if you came for the beach.
- July - September: Peak Heat. August and September are the worst months. This is when the triple-digit days happen. If you’re in a neighborhood like Echo Park or Silver Lake, you’re feeling the "urban heat island" effect—lots of asphalt, not enough trees.
- October - December: This is the wildcard. It can be 95 degrees on Halloween. Honestly, some of our hottest days of the year happen in October.
The Nighttime "Relief" (Or Lack Thereof)
One thing people forget is that the desert-like climate usually means it cools down at night. In a normal year, a 95-degree day turns into a 65-degree night. You open the windows, the house cools down, and you're fine.
But lately, that’s changing.

Scientists at NOAA and NASA have pointed out that 2025 was one of the hottest years on record globally, and LA felt it in the "lows." We’re seeing more nights where the temperature stays at 75 or 80. When the concrete doesn't have time to cool off, the next day starts off already hot. That's when people start getting heat exhaustion.
Surviving the Heat: Expert Tips for the Southland
If you're caught in an LA heatwave, you need a plan.
First, ignore the "walkability" of the city. In the middle of an August afternoon, walking three blocks in Hollywood feels like a marathon. Use the Metro or stay in the AC.
Second, the beach isn't always the escape you think it is. Everyone else has the same idea. The PCH (Pacific Coast Highway) becomes a parking lot. If it's 100 degrees inland, it’ll be 82 at the beach, but it will take you two hours to get there.
Actionable Steps for Navigating LA Temperatures:
- Check the "Dew Point," not just the Temp: If the dew point is under 55, it’s dry. You’ll sweat, it’ll evaporate, and you’ll stay cool. If it’s over 60 (which is rare but happening more often), it’s going to feel miserable.
- Hydrate before you’re thirsty: The dry air steals moisture from your body before you even realize you're sweating.
- Time your Griffith Park hikes: Do not go to the Hollywood Sign at 1:00 PM in July. People literally have to be airlifted off the trails every year because they underestimate the heat. Go at sunrise.
- Neighborhood Selection: If you hate heat, stay West of the 405. Santa Monica, Venice, and Culver City stay significantly cooler than the rest of the basin.
The bottom line? How hot is it in Los Angeles depends entirely on where you stand and which way the wind is blowing. It’s a city of extremes masked by a "sunny" reputation.

For the most accurate daily planning, check the National Weather Service (NWS) Los Angeles/Oxnard station. They provide specific "Zone Forecasts" because they know that a forecast for "Los Angeles" is basically meaningless in a city this big and topographically weird. Keep your sunscreen handy and your AC on blast.
