You’ve seen the postcards of white sand and emerald water, right? Biloxi usually looks like a tropical escape, but honestly, if you're looking at the 10-day forecast in biloxi mississippi right now, you might need to swap that swimsuit for a heavy sweater—or maybe a raincoat.
January on the Gulf Coast is a bit of a wild card. It’s not "winter" in the way someone from Maine would describe it, but it's a damp, bone-chilling cold that catches tourists off guard every single year.
The Immediate Outlook: A Quick Chill
Right now, Saturday, January 17, 2026, we’re sitting at a crisp 57°F with a north wind blowing at 11 mph. It’s mostly cloudy, and there’s a 10% chance of rain. Basically, it’s "stay inside and drink coffee" weather.
If you're heading out tonight, bundle up. We’re looking at a low of 35°F with light rain. It’s that soggy, North-wind-driven rain that makes it feel much colder than the thermometer says.
Breaking Down the 10-Day Forecast in Biloxi Mississippi
People think the South is always warm. They're wrong. Here is how the next week and a half actually looks:
- Sunday, Jan 18: Tomorrow is actually going to be beautiful, if a bit brisk. We're hitting a high of 50°F under full sun. The humidity drops to 36%, so it'll feel dry and sharp. The night will be the coldest of the stretch, bottoming out at 34°F.
- Monday, Jan 19 (MLK Day): Perfect parade weather for the MLK celebrations downtown. High of 56°F, sunny, and very light winds from the west at 6 mph.
- The Mid-Week Drift: Tuesday and Wednesday (Jan 20-21) stay in the mid-50s to low 60s. Wednesday night brings the rain back with a 40% chance of light showers and a low of 45°F.
- The Humidity Spike: By Saturday, Jan 24, the wind shifts to the southeast. That means moisture. Humidity jumps to 81% and we hit a high of 66°F. It’s going to feel "sticky" despite being January.
- The Rain Event: Sunday, Jan 25 is the day to stay at the casinos. There is a 75% chance of light rain during the day, and the humidity maxes out at 88%.
Why the Wind Direction Matters Here
In Biloxi, the wind is everything. When it's coming from the North (like it is today at 14 mph), it's bringing that dry, continental air that makes the sky look incredibly blue but bites at your ears.
When it flips to the South or Southeast later next week, it's dragging the Gulf of Mexico right into your living room. That’s why the 10-day forecast in biloxi mississippi shows temperatures rising toward the end of the week, but the "feel-like" temp might actually get gloomier because of the rain and fog.

What to Actually Pack
Don't be the person in shorts when it's 50°F and windy. You need layers. A windbreaker is non-negotiable because the breeze off the Mississippi Sound is constant.
Most locals live in "shackets" or light fleece this time of year. Since the UV index is still hitting a 4 on sunny days like Monday, you can still get a weird winter sunburn if you're out on the water, even if you’re shivering.
Actionable Advice for Your Trip
If you are planning to be in town for the next ten days, here is the move:
- Monitor Sunday night: With a low of 34°F, make sure you aren't leaving any sensitive plants or exposed pipes if you're a local.
- Outdoor Activities: Aim for Monday, Jan 19 or Tuesday, Jan 20. These are the "sweet spots" with the best sun-to-wind ratio for walking the Biloxi Lighthouse or hitting the pier.
- The Casino Pivot: If you’re here for the following weekend (Jan 25), have a backup plan. The 75% rain chance on Sunday means the beach is a no-go, but it’s a great excuse to check out the indoor attractions at the Beau Rivage or Hard Rock.
- Check the Water: The water temperature is hovering around 62°F. That is "heart attack cold" for a swim. Stick to the heated pools.
The 10-day forecast in biloxi mississippi proves that January is for the resilient. It’s a mix of bright, cold sunshine and gray, humid drizzle. Just watch that wind direction—it tells you more than the temperature ever will.
