Honestly, if you're looking at the Redondo Beach 10 day weather and expecting a typical "winter," you’re going to be pretty surprised. People come here in January thinking they need heavy coats and boots, but Southern California’s South Bay usually has other plans. Right now, as we move through mid-January 2026, the coast is doing that weird, beautiful thing where it feels like spring and autumn had a baby.
Basically, we’re looking at a stretch where the daytime highs are hitting the mid-70s while the nights still have enough of a bite to make you want a real fire in the pit at the beach. It’s a bit of a localized atmospheric puzzle.
The Redondo Beach 10 Day Weather Reality Check
You’ve probably seen those generic forecasts that just show a sun and a cloud and call it a day. But if you’re actually standing on the corner of Torrance Blvd and Catalina Ave, the reality is much more nuanced. For the next week or so, we’re seeing a classic ridge of high pressure keeping things unusually warm for this time of year.
Specifically, for Friday, January 16, the high is sitting at a very comfortable 73°F with nothing but sun during the day. As the sun dips behind the Santa Monica Mountains, it’ll drop to about 53°F. That 20-degree swing is what catches tourists off guard every single time.

The rest of the weekend follows suit. Saturday, January 17, actually climbs a bit higher to 74°F, though it’ll be a bit cloudier. By Sunday, January 18, we’re peaking at 75°F. If you’re planning on heading to the 19th Annual Slack Key Festival at the Performing Arts Center that afternoon, it’s going to be perfect "island vibes" weather without even trying.
A Quick Breakdown of the Upcoming Shift
Things start to mellow out as we head into next week.
- Monday and Tuesday (Jan 19-20): Sunny skies continue, but the temps dip back into the high 60s. Think 69°F and 68°F respectively.
- The Mid-Week Transition: By Wednesday, the "mostly cloudy" days return. Highs will hover around 65°F.
- The Rain Threat: Don’t pack the umbrella away just yet. Thursday and Friday (January 22-23) are showing a real chance of precipitation. Thursday night has a 70% chance of rain, and Friday daytime is looking at 70% as well, with the high temperature dropping to a chilly 61°F.
Why the Marine Layer Matters Right Now
Most people check the Redondo Beach 10 day weather and forget that the Pacific Ocean is a giant air conditioner. Even when the forecast says 75°F, if that breeze kicks up off the water—which it currently is, moving north-northwest at about 5 to 7 mph—it feels different than it does in the Inland Empire.

The humidity is sitting around 57% today. It’s not "sticky," but it’s enough to keep the air feeling soft. When that humidity spikes toward 76% during the rainier days next Friday, the "chill" will feel a lot deeper than the thermometer suggests.
Surfing and Water Temps
If you’re thinking about jumping in, the water is currently hovering around 61°F. That’s actually a few degrees warmer than the historical average for mid-January, but it's still "full 4/3mm wetsuit" territory for most of us. Surfers at the Breakwater might tell you they're fine in a spring suit during the 75°F peak on Sunday, but honestly, unless you're just doing a quick 20-minute session, you’ll want the rubber.
What to Actually Do with This Forecast
Since the Redondo Beach 10 day weather is giving us a split personality—half summer heatwave, half winter rain—you’ve gotta plan accordingly.

- The "High Heat" Window (Now through Sunday): This is your time for the Strand. Rent a bike at the Portofino or hit the Riviera Village for some outdoor dining. With the UV index hitting 2 or 3, you won't burn instantly, but the glare off the water is real.
- The "Transition" Days (Monday through Wednesday): Perfect for the Farmers' Market on Thursday at Veteran's Park or a stroll on the Pier. The air will be crisp but not wet yet.
- The "Rainy" End (Thursday night/Friday): This is when you head to the Redondo Beach Performing Arts Center or grab some clam chowder at Tony’s on the Pier while watching the storm surge.
The most important thing to remember about the Redondo Beach 10 day weather is that "mostly cloudy" doesn't mean a gray day. In the South Bay, that often means high, wispy clouds that make for the most insane pink and orange sunsets you've ever seen.
Actionable Insights for Your Visit
Don't trust the daytime high for your evening plans. If you're heading to the Pier for dinner, bring a hoodie or a light jacket even if it was 75°F at noon. The wind chill off the King Harbor marina drops the "feels like" temp fast.
Also, keep an eye on that Friday rain forecast. A 70% chance of rain in SoCal often means one heavy burst and then clearing, but with the humidity this high, it might actually linger. If you're local, it's a great day to finally check out the shops in the Riviera Village without the usual crowds.
Basically, enjoy the heat while it lasts this weekend, because by next Friday, the 61°F "winter" is finally going to show up.
