If you’re planning to hike from Hidroelectrica to Machu Picchu like I did, knowing what kind of weather to expect throughout the year is key. The climate in this region can shift quickly, and being prepared makes the difference between a great hike and a miserable one.
Here’s a breakdown of what the weather is like by season — based on my experience and what I’ve learned along the way.
This is the most popular time to visit — and with good reason. I went in July, and the days were sunny and clear, with blue skies that made the views even more stunning.
Daytime temperatures: 20°C to 27°C
Nighttime temperatures: 8°C to 13°C
Humidity: Medium
Characteristics: Clear skies, plenty of sunshine during the day. Ideal for hiking without rain. Nights can be chilly.
Pros: Great visibility, dry trails, perfect hiking weather
Cons: It can get chilly in the early morning, and it’s the busiest season — expect more people on the trail.
The hike was super enjoyable under the sun, though I was glad I had sunscreen and a hat.
This is the wet season. I haven’t done the hike in this period, but I met travelers who did, and they told me the trail can get slippery and muddy. On the plus side, the landscapes are incredibly green and lush.
Daytime temperatures: 18°C to 24°C
Nighttime temperatures: 10°C to 16°C
Humidity: High (up to 90%)
Characteristics: Frequent rain, cloudy skies, cool and very humid atmosphere. While it can get warm at times, the sun appears rarely.
Pros: Fewer tourists, vivid scenery
Cons: Risk of landslides on the road, wet shoes, and limited visibility
If you decide to go during this time, pack a poncho, waterproof shoes, and a dry bag for your electronics.
These months are kind of a mix — not fully dry but not soaked either. I once did part of the Santa Teresa route in October and only caught one or two light showers.
These months can be a sweet spot — fewer people, decent weather, and more flexibility.
Weather apps don’t always reflect what actually happens on the trail — it’s a mountain-jungle mix, and microclimates are real.
Even in dry season, occasional afternoon clouds can bring surprise showers.
Start hiking early in the day to avoid both crowds and potential afternoon rain.
The weather at Hidroelectrica changes depending on the time of year, but the hike is always doable with a little preparation. Whether you go under sunny skies or walk through a bit of jungle rain, the experience is unforgettable.
For me, the clear skies in July made it picture-perfect — but I wouldn’t mind going again in the rainy season just to see everything even greener.
