Miami is basically playing a game of meteorological tug-of-war right now. One minute you're sweatily regretting that second Cuban coffee in 84-degree heat, and the next, you're digging through the back of your closet for a hoodie because the mercury just pulled a disappearing act. Honestly, if you’re looking at the miami two week forecast, "predictable" is the last word I’d use.
We just came off a record-tying Sunday on January 11th where it hit 84°F—matching a mark set way back in 2000. But that tropical fever dream is over. A series of cold fronts are currently marching through South Florida, and they aren't just bringing a "light breeze." We’re talking about a genuine chill that’s going to make the palm trees shiver.

The Immediate Outlook: Rain Today, Shivers Friday
If you’re out and about today, Tuesday, January 13, you’ve likely noticed the clouds aren't budging. A stalled cold front is hovering over us like an uninvited houseguest. Expect high temperatures to struggle to reach 73°F, with a 75% chance of rain keeping things soggy.
It gets weirder.
Wednesday actually looks a bit warmer with a high of 74°F, but don't let that fool you. It’s just the "calm" before a second, much punchier cold front hits on Thursday, January 15. The National Weather Service is calling for scattered to numerous showers on Thursday morning as that front sweeps through. Once it passes, the bottom falls out.
Friday, January 16, is going to be a shock to the system. We’re looking at a high of only 67°F or maybe 69°F depending on which model you trust, but the real story is the overnight low. It’s expected to drop into the mid-to-upper 40s. In Miami, 45°F feels like the arctic.
Decoding the Miami Two Week Forecast: Week Two Trends
By the time we hit the weekend of January 17-18, the rain should clear out, giving us some crisp, sunny "Chamber of Commerce" weather. It’s perfect for a walk on the boardwalk, provided you aren't expecting to bake in the sun.

- Saturday, Jan 17: Partly sunny, highs near 73°F, lows around 61°F.
- Sunday, Jan 18: Sunny and bright, high of 72°F, but it stays cool at night (57°F).
- Monday, Jan 19: Expect a very dry day with 44% humidity and a high of 69°F.
As we move into the following week (January 20–26), the pattern starts to moderate. We’ll see a slow climb back into the mid-70s. By Friday, January 23, the tropical vibes return with highs hitting 77°F. However, long-range guidance from the National Weather Service suggests another potential boundary could approach by the following Monday, January 26.
Essentially, the miami two week forecast shows a "V-shaped" temperature trend: a sharp drop this week, a cool and dry weekend, and a gradual return to balmy Florida norms by next weekend.
Marine Conditions and the "Big Chill" Reality
If you were planning on taking a boat out or hitting the surf, you might want to check the small craft advisories first. These fronts are kicking up some serious wind.
Northeast winds are gusting up to 20 knots, and the rip current risk along the Atlantic beaches is currently high. Even if the sun is out, the ocean temperature is hovering around 76°F. While that sounds warm to a New Yorker, the wind chill on a moving boat will make it feel significantly colder.

Why the sudden swings?
South Florida in January is often a battleground between high pressure over the Atlantic and cold air masses sliding down from the Great Plains. When the jet stream dips low enough, it pushes these fronts all the way to the Florida Straits. That’s exactly what’s happening now. The "stalled" nature of the current front is why we’re seeing so much grey and dampness instead of a quick 24-hour storm.
How to Pack and Prepare
Forget the "only shorts" rule for the next 14 days.
You need layers. The morning of Friday the 16th and Monday the 19th will be genuinely cold for outdoor dining or morning runs. If you're visiting, pack a medium-weight jacket. You’ll also want an umbrella for the midweek dampness, though by the time the second week of the forecast rolls around, the rain chances drop significantly to around 5-15%.
Next Steps for Your Trip:
- Monitor the "RealFeel": With the wind coming off the water, a 68°F day can feel like 60°F.
- Watch the Thursday Front: This is the big transition. If you have outdoor plans on January 15, have a "Plan B" for the morning rain.
- Beach Days: Aim for the middle of next week (Jan 21-23) if you want that classic Miami heat.
The weather is shifting fast, so checking the local radar every morning is a must. Stay dry today, and get ready for some serious sweater weather by Friday morning.
