Florida weather is a bit of a tease. You think you’ve got it figured out—sun, palm trees, maybe a stray afternoon shower—and then a random Sunday in January hits you with an 81-degree high and a sudden 70% chance of rain. Honestly, the Palm Beach Gardens weather forecast for today, January 18, 2026, is a perfect example of why you can't just pack a swimsuit and call it a day.
Right now, as the sun has tucked itself away, it’s about 59°F outside. It's "mostly cloudy," which in Florida-speak basically means the sky is a giant grey blanket that might or might not leak on you. The wind is coming from the northwest at 13 mph. It’s not a gale, but it’s enough to make you regret leaving your light jacket in the car.
Today’s Numbers and Why They Matter
Earlier today, we saw a high of 81°F. That’s classic. But if you’re heading out tonight, the low is dipping all the way down to 48°F. That is a massive swing. Most tourists see "Florida" and "80 degrees" and forget that the humidity, which is currently sitting at 67%, makes that 48-degree night feel a lot crisper than you'd expect.
- Current Temp: 59°F (Nighttime)
- Wind: 13 mph from the NW
- Humidity: 67%
- Precipitation: 10% chance right now (down from 70% earlier today)
Understanding the "Gardens" Microclimate
Living here, you learn that the Palm Beach Gardens weather forecast isn't always the same as what’s happening on the beach in Jupiter or down in West Palm. We are just far enough inland that the Atlantic breeze doesn't always moderate the temperatures perfectly.

Take the rain, for instance. Today had a 70% chance of rain during the daylight hours, mostly cloudy conditions, and southwest winds at 18 mph. If you were planning on 18 holes at PGA National, you probably spent more time watching the radar on your phone than actually swinging a club.
The interesting part? The forecast for the rest of the night shows "clear with periodic clouds." The chance of rain has plummeted to 10%. This is the quintessential Florida "wait five minutes" rule in action.
The Seasonal Reality Check
If you're looking at the long-term Palm Beach Gardens weather forecast, you’ve gotta understand the cycles. January is technically our coldest month. We average a low of about 59°F and a high of 74°F normally. So, today hitting 81°F? That’s well above the historical average.
Most people get it wrong when they assume winter is just "slightly less hot."
It’s actually quite volatile.
One day it’s 85°F; the next, a cold front drops us into the 40s.
When to Actually Visit
If you’re planning a trip, the "sweet spot" is usually November through April. The humidity is lower (usually), and you aren't constantly checking the National Hurricane Center every morning. Hurricane season is the elephant in the room from June 1st to November 30th.
August is the real beast here—it’s the wettest month, averaging nearly 9 inches of rain, and it’s the hottest. If you visit then, expect to feel like you’re breathing through a warm, wet washcloth.
Actionable Tips for Navigating the Forecast
- The "Layer" Rule: For today's 48°F low after an 81°F high, layers aren't just a suggestion; they're a survival strategy.
- Wind Direction: Watch for those Northwest winds like we have tonight. They usually bring in the drier, cooler air from the mainland.
- Radar Over Apps: Don't just trust the little "cloud" icon on your phone. In Palm Beach Gardens, rain often moves in narrow bands. Use a live radar feed to see if that cell is actually hitting the Gardens or just clipping North Palm Beach.
- UV Index: Even on a cloudy day like today (UV index was 2), that Florida sun is deceptive.
Basically, if you’re out tonight, enjoy the clear patches and the break from the humidity. Just don't be surprised when you wake up and the 48-degree chill makes you question if you're actually in the Sunshine State.
