Honestly, if you're looking at the Palm Beach 10 day weather forecast right now, you might think the local meteorologist is having a bit of a laugh. One day we’re hitting a balmy $79^\circ\text{F}$, and basically the next morning, you’re digging through the closet for that one "heavy" sweater you keep for emergencies. It's Florida in January. It's predictably unpredictable.
Right now, Palm Beach is sitting at $70^\circ\text{F}$ under a partly cloudy night sky. Humidity is a thick 86%, which is pretty standard for us, but the wind is barely a whisper at 4 mph coming from the south. That’s the calm before things get interesting.
The 48-Hour Rollercoaster
Today, Sunday, January 18, is the pivot point. We’re pushing a high of $79^\circ\text{F}$ with a 35% chance of rain, but look at that low: $51^\circ\text{F}$. That is a nearly $30$-degree drop in a single day.

Why? A cold front is pushing through with some serious muscle. The wind is shifting to the west at 21 mph. If you’re out on the water or walking Worth Avenue, you’re going to feel that shift. By tomorrow, Monday, the high only hits $65^\circ\text{F}$. For locals, that’s "parka weather." For visitors from Ohio? That’s probably still shorts weather, though the 14 mph north wind might change your mind.
What the Next Week Actually Looks Like
Forget the generic "sunny Florida" postcards for a second. Here is the grit of the Palm Beach 10 day weather forecast and how it actually impacts your plans:

- Mid-Week Warm Up: Tuesday and Wednesday (Jan 20-21) see a slow climb back. We go from $72^\circ\text{F}$ to $76^\circ\text{F}$. It’s going to stay mostly cloudy, which actually makes for great golfing weather because you aren't baking under the direct UV.
- The Rain Patch: Thursday, January 22, brings light rain. It's not a washout, but with a 35% chance and $76^\circ\text{F}$ temps, it’ll be that misty, humid kind of day where your hair just gives up.
- The Sweet Spot: Next weekend, January 24-25, looks like the winner. We’re looking at $78^\circ\text{F}$ to $79^\circ\text{F}$. If you’ve been waiting to hit the beach, that’s your window.
Ocean Conditions and The "January Dip"
People always ask if you can actually swim in Palm Beach in January. The answer is a weird "yes, but." The current water temperature is around $78^\circ\text{F}$. That is actually warmer than the air is going to be on Monday morning.
But here’s the thing: once you get out of that $78^\circ\text{F}$ water into a $60^\circ\text{F}$ breeze, you’re going to freeze. Surfers are currently rocking 2mm shorties or neoprene tops, especially at the Jetties. If you’re just looking to dip your toes, the sand is going to be chilly until that sun really breaks through mid-afternoon.

Local Realities vs. The App
Don't trust the little "cloud" icon on your phone too much. In Palm Beach, a "mostly cloudy" day often means the sun is still blasting through enough to give you a moderate UV index of 4. You will still get a sunburn on Monday even if it only feels like $65^\circ\text{F}$.
The north and northeast winds we’re seeing through Friday (Jan 23) will keep the air feeling crisp. It’s that dry, "winter" air that Floridians live for. It means the mosquitoes are finally taking a break, and you can actually sit outside at a cafe without needing a personal fan and a gallon of iced tea.
Actionable Advice for the Next 10 Days
If you're in town or planning to be, here is how to handle this specific Palm Beach 10 day weather forecast:
- Layer Like a Pro: Pack for $50^\circ\text{F}$ mornings and $80^\circ\text{F}$ afternoons. It sounds dramatic because it is.
- Boat Early in the Week: The winds drop significantly by Sunday the 25th (5 mph), making it the best day for the water. Avoid the 21 mph gusts today unless you like a bumpy ride.
- Indoor Backups for Thursday: Save the Norton Museum of Art or the Flagler Museum for the 22nd when those light rain showers are most likely to pop up.
- Watch the UV: Even on the cooler days (like Monday’s $65^\circ\text{F}$), the UV index is a 4. Sunscreen is non-negotiable if you’re doing the Lake Trail.
This 10-day stretch is a classic South Florida winter mix. You get a bit of the "Arctic chill" (relatively speaking) followed by that tropical rebound. Just keep an eye on those wind directions—a north wind in Palm Beach is a completely different beast than a south breeze.
