You’ve seen the postcards. Golden sun, swaying palms, and that iconic pier jutting into a sapphire Pacific. People think Santa Monica is a perpetual 72-degree fever dream. Honestly? It’s more complicated than that.
Right now, if you’re looking at the weather in santa monica ca 10 day forecast, you’re seeing a weirdly warm spike for mid-January. We’re talking highs of 75°F today and nearly hitting 80°F tomorrow. That is not "normal" winter. Usually, we’re huddling in light Patagonia puffers with highs in the mid-60s.
The 10-Day Reality Check: January 16 - January 25
The next week and a half is a bit of a roller coaster. We’re starting off with a mini-heatwave (for us, anyway) before things settle back into that crisp coastal winter vibe.
- The Warm Front (Friday - Tuesday): It’s going to be gorgeous. Friday hits 75°F with pure sun. Saturday is the peak at 78°F, though some clouds might roll in. Sunday through Tuesday stays in the low 70s. Basically, it’s beach weather in the middle of winter.
- The Cool Down (Wednesday - Sunday): Around mid-week, the ocean remembers it’s January. Highs drop to 70°F on Wednesday and then tumble into the mid-60s by Friday. You’ll see more "partly sunny" days, which is local code for "the marine layer is hanging out a bit longer."
The humidity is also bouncing around like a toddler on espresso. It’s sitting at a bone-dry 26% on Saturday—expect some static electricity when you touch your car door—but it climbs back up to 61% by next Thursday.
Why the Forecast Lies to You (Sorta)
If you’re staying near the Third Street Promenade and your friend is over in West LA, you might be living in two different climates. That’s the Santa Monica microclimate for you.
The Marine Layer is the real culprit here. It’s this thick, damp blanket of clouds that rolls off the Pacific. In the summer, we call it "June Gloom," but it’s a year-round regular. You can wake up at 8:00 AM to a gray, misty soup that feels like London. Then, by noon, the sun "burns it off," and suddenly it’s a California dream again.

But here’s the kicker: sometimes that gray wall stays parked right at the water’s edge. You could be shivering on the sand at 62°F while someone just two miles inland at the UCLA campus is sweating in 75°F heat. When checking the weather in santa monica ca 10 day forecast, always subtract about 5 degrees if you plan on actually sitting on the beach.
The Santa Ana Wildcard
Notice those north and northeast winds in the forecast for early next week? That’s the hint of a Santa Ana event. These winds blow from the desert toward the sea, doing the exact opposite of our usual sea breeze.
They bring three things:

- Ridiculous clarity (you can see all the way to Catalina Island).
- Bone-dry air that makes your skin feel like parchment paper.
- Unexpected heat.
That’s why we’re seeing those 78°F spikes. It’s the desert saying hello to the ocean.
What to Actually Pack
Don’t be the tourist in a tank top at 6:00 PM. Once that sun dips behind the horizon, the temperature cratering is real. We’re looking at lows between 52°F and 56°F every single night this week.
- Layers are non-negotiable. A denim jacket or a light hoodie is the unofficial uniform.
- Sunscreen. Even on the "mostly cloudy" Saturday, that UV index is still hitting 2 or 3. The reflection off the water will fry you before you realize it.
- Hydration. Especially with the humidity dropping into the 20s this weekend. Your body isn't used to that kind of dry air if you're coming from the East Coast or the South.
The Verdict on the Next 10 Days
This particular window is actually one of the best times to visit. You’re missing the heavy winter rains (only a 10-15% chance of a drizzle next week) and avoiding the soul-crushing fog of late spring.
If you want the best views, aim for Monday the 19th. The air should be clear, the highs will be a comfortable 72°F, and the North-Northeast wind will keep the horizon sharp.
Your Santa Monica Action Plan:
- Morning: Don't panic if it's gray. Check the satellite feed; if it's just coastal clouds, head inland for coffee and wait for 11:00 AM.
- Afternoon: Hit the Strand. The NW winds at 6-7 mph are just enough to keep you from overheating during a bike ride.
- Evening: Be back at the pier by 5:10 PM for the sunset, but have your sweater ready the second the sun disappears.
Keep an eye on that humidity shift toward the end of next week. When it climbs back into the 60% range, the "ocean chill" feels a lot heavier, even if the thermometer says it’s only 65°F.
