Honestly, if you're looking at a weather forecast for Lima and seeing "cloudy" every single day, you might think you've made a massive mistake booking a January trip. You haven't.
Lima is a weird one. It’s a desert city sitting right on the Pacific, which means it plays by its own rules. While the rest of the world thinks summer means clear blue skies from dawn till dusk, Lima likes to play hard to get.
The Current Situation on the Ground
Right now, as of Tuesday, January 13, 2026, the city is sitting at 76°F. It feels a bit stickier though—closer to 79°F—thanks to that legendary coastal humidity that stays parked at 73%.
The wind is just a lazy 5 mph breeze coming off the west. It’s enough to keep the air moving, but not enough to blow away the "gray" that often defines the Lima skyline. If you're standing in Miraflores looking out at the ocean, it’s definitely a "t-shirt and light pants" kind of day.
Weather Forecast for Lima: The Next Few Days
Don't let the "cloudy" labels in your weather app scare you off. In Lima's summer, those clouds often burn off by mid-afternoon, or at the very least, they keep you from getting absolutely roasted by the equatorial sun.
Here is what the rest of the week is looking like:
- Wednesday, January 14: It’s heating up a bit. We’re looking at a high of 80°F and a low of 70°F. The UV index is jumping up to an 8, which is "apply sunscreen or regret it" territory.
- Thursday, January 15: A slight dip back to 78°F. There’s a 35% chance of some light precipitation. In Lima, "rain" is usually more of a mist—the locals call it garúa—that makes the pavement look shiny but won't exactly soak you to the bone.
- Friday, January 16: Expect more of that light rain/mist with a high of 79°F. The humidity is hovering around 73%, so it’ll feel pretty tropical.
Why January 2026 is Different
There’s been a lot of talk about ENSO (El Niño-Southern Oscillation) patterns this year. We’ve been coming out of a La Niña phase, which usually keeps the Peruvian coast a bit cooler.
But the latest data from the Climate Prediction Center suggests we’re transitioning to "ENSO-neutral" right now. Basically, that means the weather is behaving itself. We aren't seeing the extreme, catastrophic rains that a "Strong El Niño" brings, nor the shivering dampness of a deep La Niña. It’s just... Lima being Lima.

The Humidity Factor
You’ve gotta understand that 75% humidity at 77°F feels a lot different than that same temperature in a dry place like Phoenix. It’s a "damp heat." Your clothes might take a little longer to dry, and your hair—well, if you have frizz-prone hair, just accept your fate now.
What Most People Get Wrong About Packing
People see "South America" and "Summer" and pack like they're going to a Cancun resort. Then they land in Lima and realize the Pacific breeze is actually quite chilly once the sun goes down.
- The Layering Rule: You need a light hoodie or a denim jacket for the evenings. Even when the day hits 81°F (which we expect to see by next Friday, January 23), the temperature drops to a consistent 70°F at night. That ten-degree drop, combined with the ocean breeze, feels surprisingly brisk.
- The Sun is a Liar: Even when it’s cloudy, the UV index in Lima is brutal. We are seeing levels of 7 to 9 this week. You will get a "cloud burn" if you spend the afternoon walking the Malecón without protection.
- Forget the Umbrella: Honestly, unless there's a freak weather event, you don't need an umbrella in Lima. The rain is a fine mist. A waterproof windbreaker is more than enough.
Actionable Tips for your Lima Visit
If you are in the city this week, the best time for outdoor activities is between 1:00 PM and 4:00 PM. That's usually when the ceiling of clouds thins out enough to let the sun through.
If you're planning to head to the beaches in the south (like Punta Hermosa), Wednesday the 14th and next Tuesday the 20th are looking like your best bets for maximum Vitamin D, with highs hitting 80°F.
Keep an eye on the southwest winds—they’re staying steady at around 5-8 mph all week. It’s perfect for paragliding over the cliffs of Miraflores, as the lift is consistent without being dangerously gusty. Just make sure to book your flight for the afternoon when visibility is highest.
