Peru’s climate: fog on the coast, freezing temperatures in the Andes, and heavy rain in the rainforest
If we want to talk about Peru’s climate, we first need to be clear about which type of environment we mean. The country is divided into:
- a coastal area, densely populated, in the west along the Pacific;
- the Andes region, stretching north to south along the eastern side of the coast;
- the inland area, characterized by the presence of the Amazon rainforest.
On the coast, the climate takes itself a bit too seriously: it’s as dry as a Monday morning, with very little rain all year round. From November to May, in particular, it’s all, “Where the heck have the clouds gone?”
In winter, on the other hand (and remember that here in the Southern Hemisphere winter runs from June to September!), you’ll also wonder where the sun has disappeared to because of a light but persistent mist hanging over the coast, apparently caused by Pacific currents.
In the Andes, the climate varies depending on the season. In the driest months, from April to October, it’s sun, sun, and more sun. Temperatures, however, are a little chilly, especially as altitude increases, and the daily temperature range is brutal: in winter in Cusco, for example, you might enjoy a lovely mild day at around 20°C and then at night... Boom! The temperature drops all the way to 0°C.
The wet season, on the other hand, runs from November to March. Yes, it can be annoying to suddenly find yourself in the middle of a downpour, but here in the Andes they’re not actually that frequent. The place that really goes all in, though, is the Amazon rainforest.
Here in the green lung of the Earth, you can expect heat all year round, humidity hitting hard, and rain, sooo much rain, for almost the entire year. Because, you see, there isn’t really a true dry season here. In scientific terms, we might say there’s a “Damn, it’s raining a lot!” season (between May and September) and a “DAMN, IT’S RAINING A LOT!” season (between October and April).
It happens
So, all in all, Peru’s climate doesn’t seem too complicated, right?
Not exactly. The problem is that South America is one of the regions affected by El Niño.
You know it, right?
Every few years (anywhere from 2 to 7—El Niño pretty much decides for itself when it feels like making an appearance), it wakes up like a teenager in the middle of a full-blown crisis, throwing ocean currents and global climate patterns into chaos. And when it arrives, it can turn an ordinary rainy season into a full-on drama, with storms, wind, and sometimes even major flooding.
Its duration varies, but it typically lasts about 9 to 12 months, although some events can continue for years.
The latest El Niño event began in June 2023, with its presence officially confirmed by the World Meteorological Organization on July 4, 2023. It is still ongoing today and is expected to last at least until the middle of this year.
According to experts, this time the teenager seems to have woken up less angry than usual, and it appears that it will not reach the intensity of other events such as those in 1997 and 2015.

So, when should I actually go to Peru?
And now we’re ready to answer the question: what is the best time to visit Peru?
Beyond the differences between the various regions and their specific climates, let’s say that the best time is probably the dry season, which more or less runs from late March to October-November, give or take. In the Andes in particular, the sun shines almost all the time during these months, creating ideal conditions for trekking and for visiting spectacular places like the incredible Machu Picchu.
The rainy season (November to early March), however, also has its advantages: fewer tourists, an even greener landscape, and Peru’s waterfalls at their absolute best.
If you’re not afraid of suddenly getting drenched, you could also consider these months to enjoy one of the most amazing countries in the world.
A small note about the coastal area: since rain is rare or nonexistent here, you can choose to go pretty much whenever you like. Just keep in mind that the summer months (summer in the Southern Hemisphere, that is) are a bit more pleasant temperature-wise.
And that’s all.
All that’s left is to grab pen and paper, sit down, and think about how to organize your trip to Peru. Or, let us take care of everything and book straight away onto our next 14-day itinerary through the most colorful country in the world, an incredible Andes tour in pure Sto Gran Tour style!
