Honestly, if you think Florida is just endless sunshine and flip-flops year-round, today’s Leesburg FL weather forecast is about to give you a massive reality check. We’re currently looking at a wild swing that would make a roller coaster jealous.
Right now, as of Sunday, January 18, 2026, Leesburg is sitting under a Wind Advisory until 4:00 PM. It’s gusty. It’s gray. We’ve got a 70% chance of showers this morning, and the temperature is struggling to stay in the mid-60s. But that’s not even the real story. The real kicker is what’s happening tonight.
The Big Freeze: Why Tomorrow Morning Matters
You’ve probably heard people joke about "Florida cold," but tonight is serious. A Freeze Warning and a Cold Weather Advisory are officially in effect starting at midnight.
We are dropping fast.

The low is hitting 33°F, but with the wind chill, it’s going to feel like the mid-20s. That is "protect your pipes and bring in the pets" kind of cold. If you’ve got sensitive plants or a garden you’ve been babying, get the covers out now. This isn't just a light chill; we're looking at patchy frost across Southern Lake County that could easily kill off tender vegetation.
Monday, January 19—Martin Luther King Jr. Day—will start out freezing. Literally. Even though the sun will be out, the high is only expected to reach 56°F. Northwest winds at about 9 mph will keep that "bite" in the air all day.
The 10-Day Outlook: A Weirdly Wet Week
Once we survive the frost on Monday and Tuesday morning (which has another chilly low of 38°F), things get... damp.

The midweek transition is aggressive. By Wednesday, the temperature jumps back up to a high of 69°F, but the clouds move back in. Then, Thursday brings a 45% chance of rain. It’s that classic Florida winter humidity reset where the air starts feeling heavy again.
Here is the breakdown of what to expect through the end of the month:
- Friday, Jan 23: High of 73°F. Mostly decent during the day, but a 35% chance of light rain at night.
- The Weekend (Jan 24-25): We’re hitting the mid-70s. Expect highs of 75°F and 76°F, but don't cancel your indoor plans just yet. Both days carry a 20% to 40% chance of light rain. It's going to be "muggy" Florida again.
- Next Tuesday, Jan 27: Another front seems to be pushing through. We’re looking at a 65% chance of rain and temperatures dropping back down to a high of 59°F.
Why Does Leesburg Weather Flip-Flop Like This?
Basically, we’re at the mercy of the jet stream this time of year. When those polar air masses dip south, they hit the warm, moist air from the Gulf of Mexico. That’s why you get a 65-degree rainy morning followed by a 30-degree freezing night.

According to historical data from the National Weather Service, January is technically the coldest month for us. While our average high is usually around 69.5°F, we’ve seen extremes like the 16°F record back in 1985. We aren't hitting those record lows tonight, but 33°F is close enough to be a nuisance for most locals.
Actionable Tips for This Week
- Cover the plants tonight: Use burlap or heavy blankets, not plastic. Plastic can actually trap cold against the leaves.
- Check your tires: Drastic temperature drops like this (from 65°F to 33°F in twelve hours) cause tire pressure to plummet. Don't be surprised if your "low pressure" light pops on tomorrow morning.
- Drip the faucets: If you have older plumbing or pipes exposed to the exterior, let a tiny drip run overnight to prevent freezing.
- Plan for "The Wetness": Since the humidity is climbing back to 86% by Thursday, keep the rain gear handy. The transition from freezing dry air to humid rain is a recipe for the "winter crud" (colds and allergies), so stay hydrated.
The weather in Leesburg is anything but boring right now. Stay warm tonight, and keep an eye on those wind gusts this afternoon. It’s a "sweater in the morning, raincoat in the afternoon" kind of week.
