You've finally booked that Royal Caribbean cruise. The excitement is real. You're already picturing yourself at Thrill Waterpark or lounging on Chill Island with a Coco Loco in hand. But then, you pull up the weather forecast.
Suddenly, those little rain cloud icons start mocking you. Your heart sinks. Honestly, it happens to almost everyone heading to the Bahamas in January. But here’s the thing: those 10-day forecasts are kinda notorious for being misleading if you don't know how to read the Caribbean's weird local rhythms.
Let's look at the actual weather in CocoCay 10 days out from today, Friday, January 16, 2026. Right now, it's a crisp 65°F on the island with a 12 mph breeze coming from the north. If you're coming from Ohio or Canada, that's practically a heatwave. If you’re a local? You’re probably wearing a parka.
The Reality of the Next 10 Days in CocoCay
The forecast for the rest of today shows a high of 73°F and a low of 64°F. It’s mostly sunny, though we might see some light rain tonight. But you aren't here for today; you're looking at the week ahead.
Tomorrow, Saturday, January 17, things warm up to a high of 75°F. You’ll see "light rain" on the app with a 35% chance. Most people see 35% and think the day is ruined. In reality, that usually means a 15-minute shower that clears the air and makes the sun feel even better.
Things get a bit spicy on Sunday, January 18. We’re looking at a 70% chance of scattered thunderstorms and a high of 75°F. This is the day the wind shifts to the southwest at 18 mph. If your ship is scheduled for Sunday, be prepared for some chop.
By Monday and Tuesday, the temperatures dip slightly to highs of 70°F. The north wind picks up significantly, hitting 21-24 mph. It’s going to feel breezy. Like, "hold onto your sun hat" breezy.
Breaking Down the 10-Day Outlook
- Wednesday, Jan 21: High 73°F, Low 70°F. Expect light rain and 24 mph winds from the northeast.
- Thursday, Jan 22: High 74°F, Low 72°F. Chance of rain is around 45%.
- Friday, Jan 23: High 73°F, Low 73°F. The humidity starts to climb to 84%.
- The Final Stretch (Jan 24-26): We see a beautiful rebound. Saturday and Sunday (Jan 24-25) are looking like the winners of the week with highs of 76°F and mostly sunny skies.
Why the Water Temperature Matters More Than the Air
Everyone obsesses over the air temperature, but the ocean is the real boss in January. Right now, sea temperatures in the Bahamas hover around 73°F to 75°F.
Basically, the water is going to feel "refreshing." That’s travel-agent-speak for "cold at first." If you’re planning on doing the 13 waterslides at Thrill Waterpark, just know that the pools aren't always heated to bathtub temperatures. The exception is the Coco Beach Club, which features an infinity pool that usually feels much more manageable.
The humidity is also a factor. On Monday, January 26, the humidity is expected to hit 88%. When the humidity is that high, even a 72°F day can feel a bit sticky, but it also keeps the evening from feeling too chilly when the sun goes down.
Understanding the "Winter" Wind Patterns
The Bahamas in January is all about the wind. Cold fronts from the U.S. mainland often push down, bringing those north winds we’re seeing in the forecast for Tuesday, January 20.
When the wind hits 24 mph from the north, it can occasionally affect the ship's ability to dock at the pier. Royal Caribbean’s pier at CocoCay is a marvel of engineering, but safety is the priority. If the gusts are too high, the captain might have to make the tough call to stay at sea or head to a different port. It doesn't happen often, but it's part of the "winter cruise" gamble.
Packing for the 10-Day Forecast
Don't just pack swimsuits. You'll regret it.
You need a light jacket or a hoodie for the mornings and evenings. When it's 64°F at night with a 17 mph wind, you're going to want that layer. Also, reef-safe sunscreen is a must. Even on the "mostly cloudy" Monday (Jan 19), the UV index is still sitting at a 2. On sunny days like Friday, it’s a 4. You can get toasted before you even finish your first burger at Skipper's Grill.

Actionable Next Steps:
- Watch the Wind: If your visit falls on Jan 20-21, keep an eye on the wind speed. Anything over 25-30 mph might lead to excursion cancellations, especially parasailing.
- Book the Heated Options: If you’re worried about the 73°F water, look into the Coco Beach Club for the heated pool.
- Pack a "Cold Front" Kit: Throw a windbreaker and a pair of leggings or light pants in your suitcase just in case those north winds feel sharper than expected.
