Honestly, if you stepped outside in Huntington Beach or Irvine this morning, you probably did a double-take at your calendar. It is January 16, 2026, but the air feels like a mid-May afternoon. We’re currently sitting in the middle of a bizarre winter heat spike that has locals ditching their puffers for Patagonia shorts.
Orange County weather today is basically a masterclass in California climate whiplash. While the East Coast is bracing for "Arctic revenge" and freezing iguanas, we’re looking at a daytime high that's hitting a crisp 83°F in some inland spots. Even the coastal areas, which usually stay a bit more grounded, are seeing temperatures climb into the mid-70s.

The Santa Ana Factor: Why It’s So Dry Right Now
If your skin feels like parchment and you're getting a static shock every time you touch a door handle, you can thank the winds. We've got a light offshore flow coming from the north and northeast. It’s not a full-blown "Red Flag" event like the ones that caused the 2025 disasters, but the humidity is hovering around a desert-like 29% to 31%.
Here is the breakdown of the numbers you actually care about for today:

- The Peak: Expect that 83°F high to hit around 2:00 PM.
- The Drop: Once the sun dips at 5:06 PM, things get chilly fast. We are looking at a low of 51°F tonight.
- The Wind: Mostly calm, just a 3 mph breeze from the north.
- Precipitation: Zero. Don't even look for a cloud.
The National Weather Service in San Diego has been tracking this ridge of high pressure, and while it's great for a Friday beach day, it’s keeping the "January Thaw" a bit too literal. The UV index is a 3, which sounds low, but if you’re out on the sand at Newport or Laguna for three hours, you’ll definitely feel the burn.
What People Get Wrong About "Winter" in the OC
Most tourists come here thinking it's always 75 degrees. It isn't. Usually, January is our "wet" month—or at least our "gray" month. But today is part of a trend that Cal Fire and NOAA have been watching closely. We’re in a La Niña pattern, which basically means we get these long stretches of "above-normal" temperatures and "below-normal" rainfall.
I was chatting with a neighbor who’s lived in San Clemente since the 70s, and he mentioned how he hasn't even touched his heater this week. It's great for the utility bill, sure, but it's a bit eerie. The ground is dry. The brush is still brittle. While a significant rainfall event earlier this month helped dampen the fire threat, this current heatwave is drying things out again faster than anyone would like.
The Coastal vs. Inland Divide
Don't be fooled by the "Orange County" umbrella forecast. The microclimates here are doing their usual thing.
- Huntington/Newport: Highs around 74°F. Perfect for a light hoodie in the shade but t-shirt weather in the sun.
- Anaheim/Orange: It's much toastier here, pushing 81°F to 83°F.
- The Canyons: Watch for those gusts. Inland areas could see 30 mph gusts this morning before things settle down.
Surf Report: Is It Worth Going Out?
If you're planning on hitting the water, keep your expectations in check. The surf forecast for Huntington Beach is showing 2-3 ft waves with "semi-glassy to bumpy" conditions. Newport is looking even smaller at a flat 2 ft.
Laguna Beach is the winner today if you want a bit more punch, with 3+ ft waves reported this morning. The water temperature is still a bracing 61°F, so unless you’re one of those "polar bear" types, you’re going to want the 4/3mm wetsuit. The wind is staying light and variable, which is keeping the surface relatively clean for now.
How to Actually Dress for This Mess
Looking like a local in this weather is all about layers and fabric. Honestly, the Reddit threads are right: linen is a game changer even in January.
- Morning (6 AM - 9 AM): It's 54°F. You need a real jacket or a thick hoodie.
- Mid-day (11 AM - 4 PM): Total sun. Switch to a t-shirt. If you’re inland, shorts are totally fine.
- Evening (6 PM onwards): The temperature plummet is real. The humidity drops, and that 30-degree swing hits like a freight train. Bring the jacket back out.
Actionable Steps for Your Friday
Don't let the sunshine trick you into being unprepared. Since we're dealing with a high-dry-heat situation, here's what you should actually do:
- Hydrate more than usual: That 29% humidity will sneak up on you and give you a headache by 3 PM.
- Check your tires: These temperature swings (from 51 to 83 degrees) can mess with your tire pressure sensors.
- Plan for the sunset: It's at 5:06 PM. If you're heading to the pier for a walk, the temperature will drop about 10 degrees the second the sun disappears behind the horizon.
- Sunscreen is mandatory: Even with a UV index of 3, the clear skies mean there's zero filtration.
Orange County weather today is gorgeous, no doubt, but it's a reminder of just how volatile our "mild" climate has become. Enjoy the heat while it lasts, because by next week, the marine layer is usually waiting to reclaim its territory.
