When embarking on the awe-inspiring journey of the Lares Trek to Machu Picchu, understanding the nuances of the weather is paramount. The weather along the Lares Trek closely mirrors that of Cusco and the renowned Inca Trail. Rather than adhering to the conventional delineation of “summer” or “winter,” the trek experiences two distinctive seasons: the wet season and the dry season.
Seasons and High Travel Periods
Peru’s high travel season, marked by drier albeit colder weather, spans from May through September. Notably, June, the month of Inti Raymi in Cusco, and July stand as the pinnacle of high season, drawing in throngs of travelers seeking to immerse themselves in the rich cultural tapestry of the region.


May and September: Hidden Gems
May and September emerge as hidden gems for discerning travelers. During these months, the country beckons with fewer tourists, offering a more intimate experience. While sporadic rain may make an appearance, its impact is tempered by the overall allure of the surroundings.
Off-Peak Seasons: December to February
Venturing into the Lares Trek during December, January, and February unveils a landscape drenched in rain. Especially in the mountains, precipitation is a common companion. Yet, this period boasts lower tourist numbers and less congested trekking routes. Having extensively trekked during these months, we can attest that despite occasional downpours, the experience remains thoroughly enjoyable.
Microclimates along the Lares Trek
The climate unfurls its variegated hues along the length of the Lares Trek. In the daytime, warmth and sunshine prevail during the initial two days, followed by a touch of humidity on the last leg. Come nightfall, the first two campsites can turn frosty, while the third night brings a more temperate embrace.
Rainy Season and Verdant Landscapes
The advent of the rainy period unfurls towards the end of November, extending its watery embrace until March. The rains, at times, can be quite assertive. While the precipitation may add a degree of challenge to the trek, it bestows a bountiful gift upon the landscapes, rendering them resplendent in lush greenery.
Cusco City: Weather Demystified
From May to September, Cusco dons a sunny disposition, interlaced with a hint of chilliness during the day and a pronounced coldness at night. Temperature oscillates between 29ºF and 69ºF. This phase is characterized as semi-dry. Transitioning into October to April, occasional showers punctuate the days, accompanied by temperatures ranging from 42ºF to 72ºF. January takes the lead in rainfall with approximately 17 rainy days. It’s worth noting that this period may witness flight delays or cancellations due to inclement weather conditions.
Ideal Seasons for Lares Trek
Autumn, winter, and spring emerge as the triumvirate of seasons most conducive for embarking on the Lares Trek to Machu Picchu. Each season unfurls its own unique tapestry, promising an experience replete with awe and wonder.
Conclusions: Choosing Your Time
In the quest for the perfect time (marked by sun-drenched days and balmy nights), one must be willing to make compromises. Sensitivity to rain or coldness becomes a pivotal factor in decision-making.
- January to March: Prone to rain, advisable to avoid.
- April, November, and December: A harmonious blend of warmth and favorable weather.
- May and October: Pleasant weather with a refreshing touch.
- June, July, August, and September: The pinnacle of the year, offering impeccable weather with cool nights and minimal rainfall.
