You've probably seen the postcards. Perfectly blue water, white sand, and not a cloud in sight. But if you’re looking at a Playa del Carmen forecast 14 day search result right now, you might be seeing something a little different. Honestly, the Caribbean doesn't always play by the rules.
Currently, as of January 18, 2026, we’re looking at a weird mix. It’s 70°F tonight with a humidity level that makes it feel more like 76°F. If you’re here right now, you’ve noticed the clouds. They’re "mostly cloudy" for a reason.
The 14-Day Reality: Sun, Rain, and "Nortes"
Let's talk about the next two weeks. People panic when they see the little rain cloud icon on their iPhone. Don't. Tropical rain in the Riviera Maya is usually a 10-minute event that clears the air.
Tomorrow, Monday, January 19, we’re looking at a high of 76°F and a low of 62°F. It’s gonna be mostly cloudy, but the rain chance is only 10%. Basically, a great day for walking 5th Avenue without melting.
The rest of the week looks like this:
Tuesday stays cool and cloudy at 77°F. By Wednesday, things start warming up to 81°F, but we might get some light rain. Thursday, January 22, is the one to watch. There's a 45% chance of rain during the day. If you had a catamaran trip planned, maybe push it to Friday.

Friday, January 23, is looking like the "hero" day. Full sun, 83°F, and 0% chance of rain. That is your beach day.
Why the Forecast Changes Every Five Minutes
The Caribbean is basically a giant engine of heat and water. In January, we get these things called "Nortes" (North winds). Right now, the wind is coming from the North at 13 mph. It brings cooler air from the US and Canada down to Mexico. It’s why the humidity is sitting at a whopping 92% today but will drop to 68% tomorrow.
The locals know the drill. If the wind is from the North, the water gets choppy. If it’s from the East or Southeast, things calm down and get hotter. By next Sunday, January 25, the wind shifts Southeast, and we’ll hit a beautiful 84°F with mostly sunny skies.
The Seaweed Situation: What’s Actually Happening?
Okay, let’s address the elephant on the beach. Sargassum.

Usually, January is the "safe" month. You pay the premium price for the winter sun specifically to avoid the brown seaweed that plagues the summer. But 2026 is being... difficult. On January 8, a massive surge hit Playa Mamitas. We’re talking 25 tons of seaweed in a single day.
Experts from the University of South Florida (USF) are saying the "winter die-off" of seaweed didn't really happen this year. The water stayed too warm. So, while the Playa del Carmen forecast 14 day outlook looks decent for sun, you need to check the live webcams for seaweed.
Current strategy if the seaweed shows up:
- Head to the Cenotes. They’re freshwater, inland, and always crystal clear.
- Take the ferry to Isla Mujeres. Because of the way the island sits, the "back" side (Playa Norte) is often perfectly clear even when Playa del Carmen is hit.
- Pivot to the pool. Most big resorts like Melia or the Hiltons have massive crews cleaning the beach, but sometimes Mother Nature wins.
Packing for the "Maybe" Weather
Since the lows are hitting 62°F to 64°F this week, you’re gonna be cold at dinner if you only pack shorts. Seriously.

- A light hoodie or denim jacket. Crucial for those breezy 5th Avenue walks at night.
- Two swimsuits. The humidity is high (74% to 84% average this week), so your suit will NOT dry overnight. Damp spandex is a vibe-killer.
- Biodegradable sunscreen. If you’re hitting the cenotes (which you should), they won't let you in with the chemical stuff.
The Numbers You Actually Need
| Date | High Temp | Condition | Wind |
|---|---|---|---|
| Jan 19 | 76°F | Mostly Cloudy | 13 mph North |
| Jan 21 | 81°F | Light Rain | 13 mph NE |
| Jan 23 | 83°F | Sunny | 7 mph NE |
| Jan 25 | 84°F | Mostly Sunny | 8 mph SE |
| Jan 27 | 81°F | Cloudy | 11 mph North |
Looking at the tail end of the month, January 28 is looking like a mix of light rain and clear skies with a high of 80°F.
Practical Next Steps for Your Trip
Don't let a "cloudy" forecast ruin your mood. Some of the best photos happen when the sky has texture. If you see rain on the forecast for your arrival, use that day to hit the grocery store (Chedraui Selecto is the spot) or do your souvenir shopping.
Most importantly, keep an eye on the wind direction. North winds mean cooler, choppy water. East/South winds mean classic Caribbean heat. Right now, we're in a North wind cycle, but by the 24th, it shifts East. That’s your window for the best ocean clarity.
Check the Beachday app or local Facebook groups for the "Live" seaweed reports. Don't trust a photo from three days ago; things change with the tide every six hours. Pack a light layer for the evenings, keep your cenote plan as a backup for "red flag" beach days, and enjoy the fact that 76°F in Playa is still better than wherever you’re flying from.
Check the live Mamitas Beach webcam before you head out in the morning to see if the cleaning crews have finished.
