Honestly, if you woke up in Miami today, January 17, 2026, and felt like the air finally stopped biting, you aren't alone. After that brutal cold snap on Friday that had everyone from Hialeah to South Beach digging for parkas they haven't seen in three years, things are finally looking up. It’s a relief.
The what is the weather in miami today situation is basically a giant "thaw out" session. We are currently sitting at a very comfortable 76°F as of this afternoon. Compare that to yesterday morning when some of us were staring at thermometers in the 40s—it’s a massive jump.
The Current Vibe: Partly Sunny and Milder
Right now, the sky is doing that classic South Florida "partly sunny" dance. You get a good blast of vitamin D for twenty minutes, then a big, gray cloud rolls through to give you some shade. It’s not a bad deal.
The wind is coming in from the southeast at 4 mph, which is basically a light whisper. It’s the reason it feels so much warmer than yesterday. When the wind flips to the south or east here, it drags all that warm, moist ocean air over the pavement, and suddenly the "Arctic blast" feels like a distant memory.
Quick Stats for Saturday, Jan 17
- Current Temp: 76°F
- High for Today: 77°F
- Low for Tonight: 63°F
- Humidity: 73% (Yep, it's back)
- Rain Chance: Super low—only about 5% right now, though it might tick up to 15% later.
The humidity is sitting at 73%. You'll feel it. It’s not that "I’m drowning in soup" summer humidity, but it’s enough to make your hair act a little crazy if you’re prone to frizz.

What Most People Get Wrong About Miami "Winter"
People think Miami is just 80 degrees every single day of the year. It's not. This week proved it. We actually had a Freeze Warning on Friday for the inland areas. The National Weather Service in Miami hasn't had to issue one of those since 2022. It was a big deal for the citrus growers and anyone with sensitive plants on their patio.
But today? Today is the sweet spot.
If you are heading out to the beach, the water temperature is actually hovering around 76°F. That’s literally the same as the air temperature. It’s weirdly consistent. However, the City of Miami Beach Ocean Rescue is still warning about a moderate risk of rip currents. Don't be a hero; swim near a lifeguard. Also, keep an eye out for Purple Flags—Man-O-War have been spotted lately because of those shifting winds.

There is another cold front—yes, another one—creeping down the Florida Peninsula. It’s currently working its way through the Panhandle, where they’re actually worried about a mix of rain and "wet snow" (crazy, right?). While we won’t see white stuff falling on palm trees, that front is going to hit us Sunday afternoon.
Tonight will stay "Miami chilly" at 63°F with mostly cloudy skies. It's perfect window-opening weather.
The Sunday Shift
Tomorrow, Sunday, we might actually hit 80°F early in the day because the winds will kick up from the south ahead of the front. But once that line of clouds passes, the temperature is going to crater again. By Monday morning, we are looking at 40s and 50s again.
It's a total atmospheric rollercoaster.

Expert Tips for Navigating Today's Weather
If you're a tourist and you're looking at the what is the weather in miami today forecast thinking you're safe, here is the reality: the AC in Miami buildings is set to "Meat Locker" mode.
- Layering is the only way: Wear a light linen shirt or a t-shirt for the 77°F outdoors, but carry a hoodie for the movies or restaurants.
- Sunscreen is non-negotiable: Even with "partly sunny" skies, the UV index hit a 3 today. That's enough to give you a "pink glow" you didn't ask for.
- Footwear: Ditch the heavy boots you wore yesterday. Sandals are fine, but maybe keep some sneakers handy if you're walking Wynwood—the humidity can make the sidewalks a bit slick if a stray sprinkle hits.
Basically, enjoy the 76°F while it lasts. By tomorrow night, the wind is going to start howling out of the northwest, and you’ll be looking for that heavy blanket again. South Florida weather in January is nothing if not moody.
Your Action Plan: Get outside before 4:00 PM today to catch the best light and the warmest temps. If you have outdoor plants that hated the freeze on Friday, give them a good watering today while it’s mild; they’ll need the strength before the next dip on Sunday night.
