If you woke up in Miami Beach this morning expecting a tropical sweat-fest, honestly, you’re probably staring at your suitcase in confusion right now.
It’s chilly. Like, " locals-digging-out-parkas" chilly.

The weather report for miami beach fl for Friday, January 16, 2026, is essentially a tale of two cities. Earlier today, we saw some of the coldest air to hit South Florida in nearly four years. We’re talking morning lows that dipped into the 40s, with wind chills making it feel like the 30s in some spots. While the sun eventually poked through to bring things up to a high of 69°F, it wasn’t exactly "lay on the sand in a bikini" weather.
What’s Happening Right Now?
Currently, it’s about 68°F outside. It feels a bit warmer—around 76°F—mostly because the humidity is sitting at a comfortable 56% and the wind is a gentle 7 mph coming from the southeast.
The sky is mostly cloudy, and there’s a tiny 10% chance of rain. Basically, it’s a great night for a walk on the boardwalk, provided you’ve got a light jacket.
The Weekend Outlook: It Gets Better (Mostly)
If you’re here for the weekend, don't panic. The deep freeze is moving out.
Saturday, January 17, looks way more "Miami." We’re expecting a high of 76°F and a low of 66°F. It’ll be partly sunny, though the humidity is going to climb to about 70%. There is a 25% chance of a stray shower during the day, so maybe keep an umbrella in the car, but don't let it ruin your brunch plans.
Sunday is where things get interesting. We’re looking at:
- A high of 79°F.
- Humidity jumping to 73%.
- Wind speeds kicking up to 20 mph from the west.
- Cloudy skies all day.
Then, because Florida weather loves a plot twist, a second cold front is expected to sweep through late Sunday night. By Monday, we’re back down to a high of 68°F. It’s a literal atmospheric roller coaster.
Why the Weather Report for Miami Beach FL Matters This Week
You’ve got to remember that January is statistically the coolest and driest month for us. While tourists from New York think 65°F is a heatwave, for the local ecosystem and the people living here, these 40-degree dips are a big deal.
The National Weather Service even had a Cold Weather Advisory in effect earlier today. When it gets this cold, you actually have to worry about the "falling iguanas"—yes, that’s a real thing. When temperatures drop below 40°F, iguanas go into a sedative state and lose their grip on tree branches.
Can You Still Swim?
The ocean doesn't care about a temporary cold front as much as the air does. The sea temperature around Miami Beach is holding steady at about 76°F.
That’s actually warmer than the air was this morning!
If you’re a surfer, you’ll probably want a 2mm top because that 7-12 mph wind will make you feel the "evaporative cooling" the second you step out of the water. For casual swimmers, it’s "barely acceptable" if you’re brave, but most locals won’t touch the water until it hits 80°F again.
What to Pack If You’re Heading Here
Honestly, just layer.
Don't be the person who only packs shorts and a tank top. You’ll end up buying an overpriced "I Heart MIA" hoodie at a gift shop just to survive the evening.
- Light layers: Think linen for the afternoon and a fleece or denim jacket for the 50-degree nights.
- Windbreaker: Especially for Sunday when those 20 mph gusts start hitting the coast.
- Moisturizer: The air is drier than usual right now, and that salt spray plus wind can do a number on your skin.
Tomorrow’s UV index is a 3, which is moderate. Even if it’s cloudy and "cool," that Florida sun is still doing its thing through the haze. Put on the SPF.
The bottom line? This isn't the week for a record-breaking tan, but it's perfect for exploring the city without melting into the pavement. Enjoy the crisp air while it lasts, because the 90-degree humidity will be back before you know it.
Actionable Next Steps:
- Track the Front: Watch for the wind shift late Sunday afternoon; that’s your signal that the temperature is about to drop again.
- Beach Safety: Check the flags at the lifeguard towers; even with mild winds, the recent front can create unpredictable rip currents.
- Dining: Aim for outdoor seating on Saturday afternoon when it hits 76°F, but book indoor reservations for Monday evening.
