Florida weather is a bit of a cliché, right? Everyone thinks it’s just non-stop sunshine and humidity that turns your hair into a local landmark. But honestly, if you’re looking at the Boynton Beach weather report for today, Saturday, January 17, 2026, things are looking a lot more nuanced than just "hot."
Right now, it’s actually pretty gorgeous out there. The current temperature is sitting at a comfortable 77°F. We’ve got mostly cloudy skies, but don’t let that dampen your plans. The humidity is at 60%, which, for South Florida, is basically a crisp autumn day in the Northeast. You’ve probably felt that gentle breeze if you’ve stepped outside—it’s coming from the southeast at about 5 mph.
What to Expect for the Rest of the Day
If you’re planning a late lunch at the marina or a walk through the Green Cay Nature Center, here’s the deal. The high for today is staying right where we are at 77°F. It’s not going to get much sweatier than this. As we move into the evening, the temperature is expected to dip down to a low of 62°F.
You might see "partly sunny" in the forecast, but the clouds are definitely winning the territory war today. There’s a slim 15% chance of rain during the day, and that stays the same through the night. Basically, you probably don’t need the umbrella, but maybe keep it in the trunk just in case the Atlantic decides to be moody.
The Breakdown of Today's Numbers
- High Temp: 77°F
- Low Temp: 62°F
- UV Index: 3 (Moderate - you still need sunscreen!)
- Wind: 8 mph from the East
- Humidity: Averaging around 67% for the full 24-hour cycle
The Weirdness of January in Boynton Beach
Historically, January is usually the "coldest" month for us. I say "coldest" with heavy air quotes because, while the rest of the country is shoveling snow, we’re complaining if we have to put on a light cardigan. The average high for this time of year is usually around 74°F, so today is actually a few degrees warmer than the historical norm.

What’s interesting about the Boynton Beach weather report lately is how consistent the cloud cover has been. We’re seeing about 37% cloud cover on average this month. It makes the UV index of 3 feel deceptive. People think because they don't see the sun, they aren't getting toasted. Trust me, the Florida sun doesn't care about clouds; it'll still find you.
Planning Your Weekend
Looking ahead to tomorrow, Sunday the 18th, things might shift a little. We’re expecting a high of 82°F with mostly cloudy skies. The wind is going to kick up a bit more, coming from the West at 10 to 20 mph. If you’re a boater, that’s the stat you really need to watch.
The start of the work week on Monday, January 19, looks like a total pivot. We’re talking a high of 67°F and a low of 55°F. That’s a 15-degree drop in the daytime high compared to Sunday. This is that classic Florida "winter" where you’re in flip-flops at noon and a puffer jacket by 6:00 PM.
Actionable Takeaways for Locals and Visitors
- Dress in layers today. 77°F is perfect, but that 62°F tonight will feel chilly once the sun goes down.
- Hydrate regardless. Even at 60% humidity, the salt air can dry you out faster than you realize.
- Check the tides. If you're heading to the beach, remember the wind is coming from the East at 8 mph today, which might bring in some light chop.
- Sunscreen is non-negotiable. A UV index of 3 is enough to cause a burn during peak hours (10 AM to 4 PM) if you're fair-skinned.
Basically, enjoy today. It’s that rare window where the air is moving, the sun isn't trying to melt your car tires, and the rain is mostly staying offshore.
