You’ve stepped outside today in Boca Raton and probably thought you knew what to expect. It's Florida, right? But the boca raton fl weather today is pulling a bit of a fast one on anyone heading out to Mizner Park or hitting the sand at Red Reef. We are looking at a massive 31-degree gap between the daytime peak and the overnight chill.
Honestly, it’s the kind of day where a t-shirt at lunch feels like a mistake by dinner.

Currently, the mercury is sitting at 67°F, but because of the 71% humidity, the "feels like" temperature is actually hanging around 76°F. That’s a classic South Florida humidity trick. Even when the actual air isn't scorching, that moisture holds the heat against your skin. The wind is currently coming from the northwest at 13 mph, which usually signals a shift in the air mass. If you’re out right now, it’s mostly cloudy, and there is a lingering 20% chance of rain tonight.
What the Highs and Lows Really Mean for Your Sunday
Earlier today, we hit a high of 80°F. It was cloudy and felt like a standard winter day in the subtropics. But don't let that warmth fool you. Tonight, the forecast shows the temperature dropping all the way down to 49°F.
That is a significant drop for this area.
When people search for boca raton fl weather today, they usually expect a flat line of warmth. A low of 49°F is enough to send locals scrambling for the space heaters they haven't touched in a year. The sky is expected to clear up as the night progresses, which is exactly why the temperature is going to tank. Clouds act like a blanket; without them, all that daytime heat just radiates right back into space.
Basically, if you’re planning on being outdoors after sunset, you need a jacket. Not a light windbreaker—an actual jacket.

The Wind and Rain Factor
Wind is a major player in how the boca raton fl weather today actually treats you. While the current wind is northwest, the daily average has been dominated by a southwest wind at 14 mph.
That switch from southwest to northwest is the tell-tale sign of a cold front pushing through.
Precipitation isn't a huge threat, but it's not zero either. We had a 25% chance of rain during the day, which has now tapered off to a 10% chance for the overnight hours. You likely won't need an umbrella for the rest of the evening, but the dampness from the 72% daily humidity means the air will feel biting once that temperature hits the 50s.
UV Index and Safety
Even though it was cloudy for most of the day, the UV index was a 2.
It sounds low. It is low. However, Florida clouds are notorious for letting through enough UVA radiation to catch you off guard if you're spending hours outside. Today wasn't a "burn in ten minutes" kind of day, but it’s a reminder that "cloudy" doesn't mean "protected."
Preparing for the Nighttime Chill
Most people moving to South Florida forget that January can actually get cold. Not "Northern cold," but cold enough to impact your home and plants. With a low of 49°F on the horizon, tonight is the night to bring in any sensitive tropical potted plants you might have on the patio.

Check your tire pressure too. A sudden 31-degree drop in temperature can cause your "low tire pressure" light to pop up in the morning as the air inside the tires compresses. It’s a minor annoyance, but one that happens every time we get a dip like this.
If you're heading out for a late-night walk or an early morning coffee tomorrow, expect clear skies but a very crisp atmosphere. The transition from mostly cloudy to clear will be complete by the early hours of Monday.
To stay comfortable, layering is your best friend today. Start with a light base and have a heavy fleece or a medium-weight coat ready in the car. By the time you’re heading home, you’ll be glad you didn't trust the 80-degree afternoon high.
