So, you’ve finally booked that cruise, and your eyes are glued to the Coco Cay weather forecast. It’s basically a ritual at this point. You check the app, see a little rain cloud icon, and immediately start panicking that your $150 Thrill Waterpark pass is going to be a total wash.
Honestly? Take a breath. The weather in the Bahamas, especially at a private spot like Royal Caribbean’s Perfect Day at Coco Cay, is way more nuanced than a single icon on your phone.

Right now, looking at the data for mid-January 2026, things are looking a bit "mixed bag," but in that specific tropical way that usually ends up being totally fine. Today, Saturday, January 17, 2026, the temperature is sitting at a comfortable 75°F, though it "feels like" 78°F thanks to the 74% humidity. We've got a mostly cloudy sky and a light breeze coming from the southeast at 10 mph.
If you're stepping off the ship tomorrow, Sunday, January 18, don't let the "scattered thunderstorms" label ruin your breakfast. Yes, the chance of rain is high—65% during the day and 75% at night—but in the Bahamas, "scattered" often means a twenty-minute downpour followed by blinding sun. The high will be 77°F, and the wind is going to kick up a bit to 19 mph from the south.
The Reality of the "Rainy" Forecast
People see a 60% chance of rain and think the sky is falling. It’s not. Most of the time, these storms are fast movers. One minute you’re scurrying for cover under a tiki hut at Chill Island, and the next, you’re reapplying sunscreen because the clouds literally evaporated.

The start of the week actually looks like it’s cooling down a touch. Monday, January 19, brings a high of 73°F and some light rain, but the wind is the real story here. It’s shifting to the north and gusting up to 23 mph. If you’re planning on doing the Up, Up and Away balloon ride, keep your expectations in check—that thing is a diva when it comes to wind.
Tuesday and Wednesday (January 20-21) stay in the low 70s, specifically 72°F and 74°F. The wind hangs around the 22-25 mph range from the northeast. It’s actually kinda nice if you hate sweating, but the water might feel a bit "brisk" if you're used to bathtub temperatures.
Seasonal Vibes You Need to Know
If you're planning further out into 2026, you've gotta understand the two-season rule of the Bahamas. It's not four seasons; it's basically "Dry and Pleasant" vs. "Wet and Spicy."
- The Dry Season (November–April): This is where we are now. It’s peak season for a reason. Humidity is lower, and the temperatures hover between the mid-70s and low 80s. January is historically one of the coolest months, with averages around 70°F to 75°F.
- The Wet Season (May–October): This is when the heat really cranks up. You're looking at upper 80s or low 90s. This also overlaps with hurricane season, which officially starts June 1 and peaks around September.
What About the Water?
This is the part most people forget to check. You can have a sunny 80-degree day, but if the water temperature is 72°F, that first jump into the wave pool is going to be a shock to the system.
In January, the sea temperature around Coco Cay is usually around 75°F (24°C). For some, that’s perfect. For others who want that tropical bathwater feel, you might find it a little chilly for long snorkeling sessions without a thin rash guard. By the time May rolls around, the water climbs to about 79°F, and it hits its peak in August at a whopping 82°F.

Don't Trust the 10-Day Forecast Too Early
Seriously, looking at a Coco Cay weather forecast more than three days out is a fool’s errand. The island is small, and the weather patterns are influenced by the Gulf Stream and moving cold fronts from the Florida coast.
Looking at the tail end of the current January stretch:
- Thursday, Jan 22: Scattered thunderstorms again, high of 76°F.
- Friday, Jan 23: Partly sunny, 74°F. This is looking like the best beach day of the week.
- Saturday, Jan 24: Mostly sunny, 74°F, east wind at 19 mph.
- Sunday, Jan 25: Steady at 73°F and sunny.
Actionable Tips for Your Coco Cay Day
- Pack a light jacket. No, seriously. If you’re sailing in January or February, the boat ride back to the ship when you're wet and the sun is setting can be surprisingly cold.
- Download the Royal Caribbean app. They track the weather specifically for the island and will update you in real-time if excursions like the balloon or water slides have to close due to wind.
- Watch the wind direction. If the wind is coming from the North or Northeast (like it will be on Jan 20-21), the "Chill Island" side of the island might be a bit choppier. Head to the more protected areas like South Beach if you want calmer water.
- Morning is king. Even on rainy days, the mornings are often clear. Get off the ship as soon as it clears for "all ashore" to get your sun time in before any afternoon tropical showers roll through.
- Don't cancel your plans. Unless the cruise line cancels the excursion for you, show up. I've seen people skip the waterpark because of a gray morning, only for the sun to come out at 11:00 AM to a completely empty park with zero lines.
Basically, the weather at Coco Cay is part of the adventure. A little rain just keeps the crowds away, and honestly, you're going to be wet in the pool anyway, right? Keep an eye on those wind speeds if you're a fan of the heights, but otherwise, just grab a Coco Loco and enjoy the vibe.
