Right now, if you’re standing on the sand near the Boynton Inlet, it’s a pretty decent night. Honestly, the temperature in Boynton Beach Florida is sitting at exactly 71°F. It feels a bit warmer though—about 76°F—mostly because the humidity is hanging out at 72%.
There is this weird myth that Florida is just one giant, sweltering sauna 365 days a year. People think you’re either melting or stuck in a hurricane. But January in Boynton? It’s basically the "Goldilocks" zone. Not too hot, definitely not cold.
Today, Saturday, January 17, we saw a high of 75°F. That’s pretty much the sweet spot for anyone who hates shoveling snow but also doesn't want to sweat through their shirt just walking to the car. Tonight, it’s looking to drop down to about 61°F. You might actually want a light hoodie if you’re doing a late-night stroll along Ocean Blvd.
The Reality of the Temperature in Boynton Beach Florida
The thing you’ve gotta realize about this part of Palm Beach County is that the Atlantic Ocean is a giant mood-setter.

In the summer, specifically August, things get intense. We're talking average highs of 90°F. But here is the kicker: the "feels like" temp (the Heat Index) often screams past 100°F because the humidity in the late summer is thick enough to chew. If you’re visiting then, you aren't just looking at the temperature; you’re looking for the nearest AC unit or a very cold pool.
Compare that to right now. In January, the average high is usually around 76°F, and the low is 58°F. It’s "winter," Florida style.
The Breakdown by the Numbers
If you’re the type of person who needs the data to plan a trip, here is how the year usually shakes out:
- The Hottest Stretch: June through September. Expect 86°F to 90°F daily.
- The "Perfect" Window: November to April. This is when the snowbirds arrive, and for good reason. Highs stay between 73°F and 81°F.
- The Ocean Factor: Interestingly, the water temperature in Boynton Beach is currently around 77°F. Yes, the ocean is actually warmer than the air tonight.
Why Does It Feel Different Than the Thermostat Says?
Humidity. That’s the short answer.
In Boynton Beach, the humidity rarely takes a day off. Even today, with a "comfortable" air temp, that 72% humidity makes the air feel heavier. It's why 71°F in Florida feels like 76°F, while 71°F in Arizona feels like you need a sweater.
Wind also plays a huge role here. Right now, we’ve got a gentle 4 mph breeze coming from the east. It’s barely enough to rustle a palm frond, but when those northeast winds kick up to 15 or 20 mph in the spring, it can actually feel quite brisk on the coast.
What to Pack Right Now
Since the temperature in Boynton Beach Florida is currently 71°F and heading toward a low of 61°F, your packing list shouldn't be all bikinis and board shorts.

- Layers are king. A light windbreaker or a denim jacket is essential for the evenings.
- Breathable fabrics. Even in January, cotton and linen are your best friends during the day when the sun is hitting 75°F.
- The "Rain Gear" Lie. People bring heavy raincoats. Don't. If it rains (and there’s a small 10% chance tonight), it’s usually a quick 10-minute dump and then the sun comes back. A cheap poncho or a small umbrella is plenty.
The Secret "Shoulder" Season
If you want the best of both worlds, aim for May or October.
In May, the water starts feeling like bathwater (hitting about 81°F), but the soul-crushing humidity of July hasn't quite settled in yet. October is similar, though you have to keep an eye on the tropical forecasts.
Honestly, if you're looking at the temperature in Boynton Beach Florida today and thinking about booking a flight, just do it. 75°F daytime highs and 61°F nights are about as good as it gets in the Continental US this time of year.
Next Steps for Your Trip:
Check the local tide charts if you plan on visiting the Boynton Inlet, as the water movement can be aggressive during tide changes. If you’re heading out tonight, keep that light jacket handy—that 61°F low will feel cooler than you expect once the sun is gone.
