Honestly, if you've lived in South Florida long enough, you know the drill. You wake up expecting a tropical paradise and end up hunting for that one denim jacket you buried in the back of the closet three years ago.
Right now, the boca raton weather forecast is doing that weird January dance where it can't quite decide if it wants to be a beach day or a "stay inside with hot cocoa" kind of vibe. We’re currently sitting at a crisp 64°F on this Friday night, January 16, 2026.

It's chilly. Like, actually chilly for us.
The wind is coming in from the southeast at about 5 mph, and the humidity is hovering at 67%. It’s mostly cloudy out there, and if you’re planning on a late-night walk along A1A, you’re looking at a 10% chance of rain. Basically, it’s sweater weather, Boca style.
The Cold Front Reality Check
Everyone thinks Florida is just a flat heat-pancake all year. They’re wrong.
Today, Friday, saw a high of 68°F, but the low is dipping all the way down to 43°F tonight. That’s a massive swing. If you’re out west near the Turnpike or heading toward the Everglades, it’s probably going to feel even colder. The local experts over at the National Weather Service have been keeping a close eye on this front, and it’s a sharp reminder that winter in the 561 isn't always just sunshine and iguanas falling out of trees.
Speaking of iguanas, when the mercury hits these levels, they really do lose their grip. It’s a real thing.
But don't get too comfortable in your boots.
Tomorrow, Saturday, January 17, things start to moderate. We’re looking at a high of 76°F and a low of 61°F. It’ll be partly sunny, though the clouds will thicken up as the day goes on. The wind shifts a bit, coming from the southeast at 7 mph.
Breaking Down the MLK Weekend Outlook
If you’re planning to hit the Martin Luther King Jr. Day events, you need to be ready for some serious atmospheric mood swings. Sunday, January 18, is going to be the "warm" day of the bunch.
We’re talking a high of 78°F.
It’s going to get breezy, though. West winds will be kicking up to 18 mph, so maybe skip the wide-brimmed hats if you’re headed to a parade. There’s a 20% chance of rain during the day, which isn't much, but enough to make the air feel a bit "soupy" again before the next front hits.
Then, Monday rolls around. The holiday itself looks gorgeous but cool. A high of only 67°F and a low of 51°F. It’ll be mostly sunny, which is perfect for being outdoors, but you’ll definitely want a layer. The wind will be coming from the north at 11 mph, bringing in that dry, Canadian air we only get a few times a year.
Looking Ahead: The 10-Day Vibe
What’s wild about the boca raton weather forecast as we move deeper into January 2026 is how consistent the inconsistency is.
- Tuesday, Jan 20: Partly sunny, 71°F high, 59°F low. North wind at 13 mph.
- Wednesday, Jan 21: Mostly cloudy with a slight chance of light rain at night. High of 75°F.
- Thursday, Jan 22: This is when it gets damp. 35% chance of rain with a high of 77°F.
- Next Weekend (Jan 24-25): We climb back up toward the 80s. Expect highs of 78°F to 79°F with a lingering chance of showers.
Basically, if you’re a gardener in Boca, you’re probably stressed. These temperature swings are tough on tropicals.
According to records from the local weather stations, January usually averages a high of 74°F and a low of 65°F. We are currently trending a bit cooler than that, especially with those nighttime lows hitting the 40s and 50s. It’s not record-breaking—Boca has seen it dip into the low 40s as recently as early 2022—but it’s enough to make the locals complain.
Survival Tips for a Boca Winter
Honestly, the biggest mistake people make is thinking the "chance of rain" means their day is ruined. In South Florida, a 20% chance of rain usually means a ten-minute shower that clears the air and brings out a rainbow.
Don't cancel your tee time at Boca Raton Municipal just because the app says it might drizzle.
But do pay attention to the marine forecast if you’ve got a boat at the Inlet. The National Weather Service often issues Small Craft Advisories during these fronts because the northerly winds can make the Gulf Stream get really "sporty." We're seeing wave heights occasionally reaching 8 feet in the offshore waters tonight.
Keep an eye on your sensitive plants, too. While we aren't looking at a hard freeze, tropicals like hibiscus and orchids don't love it when the temperature drops 20 degrees in six hours.
Check your tire pressure. This is the time of year when everyone’s "low tire" light comes on because of the drop in ambient temperature. It’s a classic Florida winter rite of passage.
Plan your outdoor activities for Monday or Tuesday if you want that crisp, clear sky, but keep the umbrella handy for the following Thursday. The transition from the dry air of the front back to the humid easterly flow is always a bit messy.
The best way to handle this stretch of weather is to just embrace the "winter" while it lasts. By July, we’ll all be dreaming of 64°F and a 5 mph breeze.
For now, enjoy the break from the sweat.
Grab your light jacket, head to Mizner Park, and appreciate the fact that you aren't shoveling snow.
