If you’re staring at a screen right now looking for a 15 day forecast Myrtle Beach SC, you’re probably either planning a quick escape or you're a local trying to figure out if it’s finally time to put the heavy coats away. Honestly? Predicting coastal weather two weeks out is kinda like trying to guess which way a seagull will fly when you drop a French fry. It’s chaotic.
But here is the deal. As of mid-January 2026, the Grand Strand is throwing us some serious curveballs. We aren't exactly in "sit on the beach in a bikini" territory, but we aren't quite in a frozen tundra either.
The Reality of the Next Two Weeks
Right now, the current temperature is sitting at a crisp 42°F, and with a bit of a southwest wind, it actually feels closer to 36°F. Not exactly tropical. If you’re heading out today, Saturday, January 17, we are looking at a high of 62°F with mostly cloudy skies. That’s actually pretty decent for a walk on the Boardwalk, provided you’ve got a hoodie.

Things get a little weird tomorrow, Sunday the 18th. The forecast is calling for a high of only 46°F with a 75% chance of rain during the day. But wait—check this out: there is actually a 25% chance of snow on Sunday night. Yeah, you read that right. Snow in Myrtle Beach. It’s rare, it’s dramatic, and it usually melts before you can even take a photo, but it’s on the radar.
A Quick Look at the Numbers
If you’re trying to plan your life, here is the vibe for the upcoming week based on the latest data:
- Monday (Jan 19): Sunny but cold. High of 49°F and a low of 30°F.
- Tuesday (Jan 20): Partly sunny. High 46°F, Low 30°F.
- Wednesday (Jan 21): Cloudy. High 51°F, Low 32°F.
- Thursday (Jan 22): Staying cloudy. High 55°F, Low 35°F.
- Friday (Jan 23): Mostly sunny. High 54°F, Low 35°F.
Basically, it's a "layer up" kind of week. You’ll want the sunglasses for Monday, but you’ll definitely want the wool socks too.
Why the Forecast Changes So Fast
The Atlantic Ocean is a massive engine that drives everything here. Even though the air might be 60 degrees, that water is hovering around 50°F to 55°F. That cold water acts like a giant ice pack for the coastline.

Most people don't realize that January is actually the coldest month of the year for the Grand Strand. While the "15 day forecast Myrtle Beach SC" might show some temps creeping into the 50s and 60s, the humidity (currently around 77%) makes that cold air "bite" a bit more than it would in a dry climate like Arizona.
What to Actually Do
Since the ocean is too cold for a swim—unless you’re one of those Polar Plunge types—you’ve gotta pivot.
- Restaurant Week: It's running through January 18. This is the best time to hit the fancy spots on the MarshWalk or downtown without the insane summer wait times.
- Indoor Fun: Places like Ripley’s Aquarium at Broadway at the Beach or the SkyWheel (which has temperature-controlled gondolas!) are lifesavers when that 12 mph wind starts kicking up off the water.
- Shelling: Honestly, the best shelling happens right after a storm or a high-wind day like we’re seeing this weekend. Bundle up and hit the sand; you'll find much better treasures than you would in July.
Long Range Vibes: Late January into February
Looking further out toward the end of the month, we see a bit of a rollercoaster. Monday, January 26, is showing a 65% chance of snow at night with a low of 32°F. By Tuesday the 27th, we’re looking at a high of 45°F with more snow chances during the day.
It’s a weird winter. Usually, February starts to see things crawl back toward the 60s, but for now, the "Arctic Revenge" that meteorologists are talking about seems to be clipping South Carolina.
Expert Packing Tip
Don't just pack for the highs. In Myrtle Beach, the temperature can drop 20 degrees the second the sun goes down behind the hotels. If the forecast says 55°F, pack like it’s 40°F. Wind chill on the beach is a real thing, and it doesn't care about your vacation photos.
The best way to handle the 15 day forecast Myrtle Beach SC is to stay flexible. If it rains Sunday, hit the Tanger Outlets or a bowling alley. If Monday is clear and 49 degrees, grab a coffee and hit the state park trails. The crowds are gone, the prices are low, and as long as you have a jacket, the "winter" version of the beach is actually pretty peaceful.
Keep an eye on those Sunday and Monday night snow chances—it might be the only time this year you see white flakes on the sand.
Your Next Steps:
Check the 48-hour window before you leave, as coastal systems shift fast. If you're coming this week, prioritize indoor attractions for Sunday and Tuesday when the temperatures and precipitation are at their worst. For the best experience, book your dinner reservations now to take advantage of the final days of Restaurant Week.
