You've probably looked at your phone’s weather app three times already today. If you’re planning a trip to the Lowcountry right now, that 14 day forecast hilton head sc probably looks like a chaotic rollercoaster of numbers. One day it’s a breezy 62°F, and the next, you’re looking at a low of 30°F that makes you want to crawl back under the covers.
I’ve spent enough time on this island to know that the "average" temperature is basically a myth used to sell postcards.
Honestly, January and February in Hilton Head are less about "winter" and more about a confused spring that occasionally remembers it’s supposed to be cold. Right now, as we move through mid-January 2026, the island is playing its usual games. We’re seeing a stretch where daytime highs are dipping from the low 60s down into the 40s within a 48-hour window. If you aren't prepared for that 20-degree swing, you’re going to end up buying a very expensive, very touristy sweatshirt at Coligny Plaza.
Reading the 14 day forecast hilton head sc Without Losing Your Mind
The biggest mistake people make is looking at the high temperature and thinking, "Oh, 55 degrees? That's fine."

It’s not fine.
Not when you factor in the dampness from the Atlantic and the way the wind whips off the Calibogue Sound. A "sunny" 50-degree day on the golf course feels much colder than 50 degrees in a landlocked city like Atlanta or Charlotte.
- The Mid-January Reality: Current data shows we’re heading into a chilly dip. Thursday, January 15th, and Friday, January 16th, are looking particularly sharp with overnight lows hitting the freezing mark ($30^{\circ}\text{F}$).
- The Rebound: By the time we hit the weekend of January 17th, the high jumps back to 60°F.
- The "Wet" Factor: We aren't in the rainy season (that’s August), but the forecast is showing a 40% chance of rain on the 14th and 23rd. Rain at 50 degrees is a different kind of cold.
If you’re looking at the 14 day forecast hilton head sc for late January, you’ll see the "feels like" temperature is often 5 to 7 degrees lower than the actual reading. This is due to the humidity. Even in winter, Hilton Head stays relatively humid compared to the North, which makes the cold air feel like it’s clinging to your skin.
What Nobody Tells You About the Lowcountry "Winter"
Most travel guides tell you it’s "mild." I call it "variable."

One thing you’ll notice in the 14-day outlook is the UV index. Even when it’s 48 degrees out, the UV index is still sitting around a 3. That’s enough to catch a burn if you’re out on a boat or a long bike ride for four hours. Don't be the person with a sunburn and a puffer jacket. It’s a weird look.
The Ocean Temperature Trap
Let’s talk about the water. If you see "sunny and 65" in the forecast and think you’re going for a swim, I have bad news. The sea surface temperature at Folly Field Beach is currently hovering around $55^{\circ}\text{F}$. For context, most people find anything under $70^{\circ}\text{F}$ to be "gasp-inducingly cold." Unless you’re a local "Polar Bear" club member or you’ve got a 4/3mm wetsuit, stay on the sand.
Golfing in This Weather
If you’re here for the golf, the next 14 days are actually pretty decent. Most of the rain is forecast as "light showers" rather than washouts. The wind is the real enemy. NW winds at 16 mph (expected around the 15th) will turn a par 4 into a nightmare.
Expert Tip: If the forecast shows winds from the North or Northwest, the oceanfront holes at Sea Pines or Palmetto Dunes will be significantly colder than the inland courses like those in Hilton Head Plantation.
How to Pack Based on the Current 14 Day Outlook
Stop packing for the "high." Pack for the "swing."
You need to be able to shed layers like an onion. Start with a moisture-wicking base. Add a light fleece. Top it with a windproof shell.
- Footwear: Leave the flip-flops for the hotel room. You want closed-toe shoes for the beach walks. The sand is cold, and the dampness will seep into your soul if you’re in sandals.
- The "Dinner Jacket": Even casual spots on the island can get drafty. A light puffer vest is the unofficial uniform of Hilton Head in January.
- Headwear: A beanie might feel overkill when you leave the house, but when the sun goes down at 5:45 PM, you’ll be glad you have it.
Why the Forecast Actually Matters for Your Wallet
Low season (right now) means you can get into the best restaurants—think The Sage Room or Crane’s Tavern—without a three-week lead time. But check the 14-day rain forecast. If it looks like a washout, everyone is going to crowd the indoor spots at the exact same time.

If the 14 day forecast hilton head sc shows clear skies, head to Pinckney Island National Wildlife Refuge. The lack of foliage means you can actually see the gators and armadillos instead of just hearing them rustle in the brush. Plus, the bugs are dead. That alone makes a 50-degree day worth it.
Your Lowcountry Action Plan
Don't let a "chilly" forecast ruin the trip. Use the next two weeks to lean into the "Quiet Season" perks.
- Watch the 15th and 16th: These are the "stay inside" days. Book a spa treatment or visit the Coastal Discovery Museum.
- Target the 17th-19th: This is your window for biking. 60 degrees is the "Goldilocks" zone for the island's 60+ miles of bike paths.
- Check the Tides: Weather is only half the story. If you're walking the beach, check the tide charts alongside the forecast. A high tide during a rainstorm means there’s no hard-packed sand to walk on.
Basically, keep an eye on those overnight lows. If you see anything approaching $35^{\circ}\text{F}$ in the 14 day forecast hilton head sc, make sure your rental has a heated pool or a working fireplace. The island is beautiful in the winter, but it doesn't suffer fools who forget their jackets.
Grab a coffee at Java Burrito, throw on an extra layer, and enjoy having the beach to yourself. You won't have to fight for a parking spot at Coligny, and that’s a victory no matter what the thermometer says.
Next Step: Check your specific travel dates against the tide cycles to ensure you have enough beach for your morning walk.
