If you’re standing on the corner of Lankershim and Magnolia, checking your phone because you aren't sure if you need a light jacket or a literal fan, you've experienced the specific brand of confusion that is weather in North Hollywood. It’s tricky. People lump it in with "Los Angeles weather" like it’s all the same thing, but anyone who lives in the 818 knows better.
The San Fernando Valley is essentially a giant bowl. North Hollywood sits right in it, shielded from the cooling Pacific breezes by the Santa Monica Mountains. This geography creates a microclimate that can feel like a totally different planet compared to Santa Monica or even Silver Lake.
Honestly, the temperature difference is wild. You can drive through the Hollywood Reservoir and watch the thermometer on your dashboard climb one degree every few blocks. By the time you hit NoHo, it’s 10 degrees hotter than the basin. Sometimes more.
Why Weather in North Hollywood Isn't Just "LA Standard"
The most glaring thing about weather in North Hollywood is the heat. While the coast stays in that dreamy 70-degree range, NoHo regularly flirts with the 90s and 100s for a good chunk of the year.
July and August are intense. Most properties in the area—about 98% according to climate risk data from First Street—are at major risk for extreme heat. It’s not just "it's sunny out" heat. It’s "don't touch your car door handle" heat.
The average high in August sits around 87°F, but that’s a bit misleading. Averages hide the spikes. It is perfectly normal to see a week-long stretch where the mercury hits 102°F or 105°F. Because the area is heavily paved and lacks the dense canopy of some older neighborhoods, the "heat island effect" keeps things cooking long after the sun goes down.
The Winter "Wet" Reality
Winter is a different beast entirely.
December and January are the coldest months, with highs dropping to the mid-60s. That sounds pleasant, right? It is, until the sun sets.
Nights in the Valley get surprisingly chilly. Lows can dip into the 40s. You’ll see locals in heavy parkas because, relative to a 90-degree afternoon, 45 degrees feels like the arctic.
Rain usually shows up between December and March. We don't get a lot of it—maybe 14 to 16 inches in a "normal" year—but when it rains, it pours. The drainage in parts of North Hollywood isn't always great, so expect some massive puddles on Victory Boulevard.

The Santa Ana Factor
You can't talk about weather in North Hollywood without mentioning the Santa Anas. These are the "Devil Winds."
They happen when high pressure over the Great Basin pushes air toward the coast. As that air drops down the mountains into the Valley, it compresses. Physics 101: compressed air gets hot and dry. Very dry.
In October or November, a Santa Ana event can drop the humidity to under 10%. Your skin feels like parchment. Your hair becomes a static-electricity experiment. These winds are often the cause of the region's most dangerous wildfires, and the smoke often settles right in the NoHo basin, tanking the air quality.
Breaking Down the Seasons
- Spring (March–May): This is the sweet spot. Jacarandas start blooming, and the air is crisp. Highs stay in the 70s. It’s the best time to be outside.
- June Gloom: A real thing. The marine layer gets trapped against the mountains. It might stay grey and misty in North Hollywood until 1:00 PM, then suddenly the clouds "burn off" and it's 85 degrees.
- Summer (July–September): Arid. Brutal. Clear skies 90% of the time. You basically live in your air conditioning.
- Fall (October–November): Unpredictable. You might get a random 95-degree heatwave or a beautiful, cool autumn breeze.
What No One Tells You About Living Here
The weather actually dictates the culture. People in NoHo are early birds in the summer. If you’re going to run errands or hit the park, you do it before 10:00 AM. After that, the sidewalk becomes a griddle.
There's also the "Valley Gap." If you work over the hill in Hollywood or Downtown, you basically have to dress in layers. You leave your house in NoHo and it's 80 degrees; you get to your office in Santa Monica and it's 64 and foggy. It’s a constant struggle of taking your sweater on and off.
One weird perk? The sunsets. Because of the way the light hits the smog and the mountain dust, North Hollywood gets some of the most vibrant, purple-and-orange sky-shows you’ve ever seen.
Actionable Tips for Navigating NoHo's Climate
- Check the Air Quality Index (AQI): During fire season, don't trust the "clear" look of the sky. The valley traps particulates.
- Pre-cool your car: If you’re parking in the sun, use a windshield shade. It sounds like "grandma advice," but it's the difference between a 120-degree interior and a 100-degree one.
- Hydrate early: In our dry heat, you lose water through sweat before you even realize you're sweating.
- Plant for the heat: If you have a yard, stick to drought-tolerant natives like Sage or Yucca. Anything else will just shrivel in the August sun.
The weather in North Hollywood is a trade-off. You deal with the scorching summers for the sake of those perfect, 75-degree February days when the rest of the country is shoveling snow. Just keep a gallon of water in your trunk and an extra hoodie in the backseat, and you'll be fine.
To stay ahead of the next heatwave or storm, set up local NWS (National Weather Service) alerts specifically for the San Fernando Valley rather than just "Los Angeles," as the regional differences are too vast to rely on general city forecasts.
