You've probably heard the rumors. People think Southern California is a permanent 75-degree paradise where the sun never sets and the clouds are strictly prohibited. Honestly? That's not always the case in January. If you’re looking at the Newport Beach 14 day forecast, you’re seeing a mix of high-desert warmth and that specific, damp coastal chill that catches tourists off guard every single year.
Right now, we are sitting in a weird pocket of weather. Today, Saturday, January 17, peaked at a gorgeous 74°F. It felt like spring. But as I’m writing this at night, it’s already dropped to 60°F with a "partly cloudy" sky that feels a bit heavier than the forecast suggests. The humidity is hanging at 62%, and there’s a tiny 4% chance of rain just to keep things interesting.
If you're planning a trip or just trying to figure out if you can actually eat outside at the Fun Zone next Tuesday, you need the real numbers.
The Next Week: Sun, Clouds, and the 70-Degree Line
The big story for the next few days is consistency. We aren't seeing any massive storms rolling in from the Pacific, which is a win. Tomorrow, Sunday, January 18, is looking like the pick of the week. Expect a high of 73°F and mostly sunny skies. It’s perfect for the "Wildlife Jewels New Year Sweep" happening over at Corona del Mar State Beach.

But check the night temps. It’s hitting 52°F. That is a 21-degree swing. Basically, if you leave the house in a t-shirt at noon, you’re going to be shivering by the time you’re looking for parking for dinner.
Here is how the next few days actually look:
- Monday (Jan 19): Full-on sunny. High of 71°F, low of 53°F. No rain. Just crisp, clear air.
- Tuesday (Jan 20): Pretty much a carbon copy. 70°F high. The UV index is creeping up to a 3, so don't skip the sunscreen even if it feels "mild."
- Wednesday (Jan 21): We start seeing some "partly sunny" transitions. High remains at 70°F, but the clouds will start rolling in thicker by the evening.
It's tempting to think this "70 and sunny" streak lasts forever, but by Friday, January 23, things start to dip. We're looking at a high of only 65°F. That’s the "mildly cool" Newport that locals know well.
The Second Week: When the Rain Might Actually Show Up
The back half of the Newport Beach 14 day forecast gets a little more "winter-lite." Sunday, January 25, is currently flagging a 20% chance of light rain. Now, 20% in Newport usually means a few misty windows or a ten-minute drizzle that clears up by lunch, but the temperature will stay capped at 68°F.
By Monday, January 26, the sun tries to make a comeback with a high of 69°F, and Tuesday, January 27, pushes back up to 72°F.
The humidity stays remarkably comfortable, hovering between 42% and 65%. It's never that "sticky" East Coast heat. It’s more of a dry, salty air that makes your hair do weird things but keeps the hiking trails at Crystal Cove feeling great.
Water Temps and the "January Dip"
If you’re thinking about jumping in the ocean, God bless you. The sea temperature right now is roughly 61°F. To put that in perspective, that’s about 2.7°F warmer than the historical average for mid-January, but it’s still cold. Most surfers at the Wedge or 54th Street are rocking 4/3mm full suits right now.

Unless you’re doing a "Surf City Splash" type of polar plunge, you’ll want neoprene. The water is actually at its annual low point right now—it won't start feeling "warm" until we hit June or July.
What to Actually Pack (The Local Secret)
Most people get Newport Beach wrong because they pack for "California" generally. They bring flip-flops and tank tops.
The reality? You need layers.
Because of that 3 mph to 7 mph wind coming off the ocean, the "feels like" temperature is almost always lower than the thermometer says. When that north wind hits at 60 degrees, it bites. Pack a medium-weight sweater or a light puffer jacket for the evenings. You’ll look like a local, and you won't have to buy a $80 tourist sweatshirt at the pier because you’re freezing.
Actionable Insights for Your Visit
- Morning Fog is Real: Don't plan your "perfect beach photo" for 8:00 AM. Wait until 11:00 AM when the "marine layer" usually burns off.
- Restaurant Week Prep: Newport Beach Restaurant Week kicks off this month. With highs in the low 70s, outdoor seating is great for lunch, but book indoor tables for dinner as temps drop fast after 5:00 PM.
- Whale Watching: January is prime time for gray whale migration. The calmer winds (around 3-4 mph early next week) mean flatter seas and less seasickness on the boats.
- UV Index Trap: Even a UV index of 3 can burn you if you're out on a boat for three hours. The reflection off the water is no joke.
The next 14 days in Newport are basically a showcase of why people pay the "sunshine tax" to live here. It’s not hot, but it’s remarkably pleasant. Just keep an eye on that Jan 25 rain chance if you’re planning an outdoor wedding or a big harbor cruise. Other than that, it’s prime coastal weather.

Grab a coffee, head to the beach around noon when it hits that 70-degree sweet spot, and enjoy the fact that it's not snowing. You've got clear skies through at least Tuesday.
Next Steps:
- Check the surf reports specifically for "Blackies" or "The Wedge" if you plan on getting in the water, as swell direction can change regardless of the sun.
- Secure outdoor dining reservations for the early afternoon (1:00 PM – 3:00 PM) to catch the maximum warmth.
