Peru in March: Weather, Crowds & What to Expect

Northern Coast (Tumbes & Piura)

The rains usually peak around March in Piura and Tumbes: rivers like the Chira and Piura can rise rapidly during sustained storms, and some rural roads are liable to washouts. Temperatures remain high and humidity oppressive; beaches are lively but inland trips to markets or archaeological sites can be disrupted. If visiting for fishing or birdwatching, ask local guides about safe launch points and avoid crossing swollen streams.

Central Coast & Lima (Lima, Paracas, Ica)

March starts to show a shift: Paracas and the Ica desert remain hot by day, but Lima’s mornings and evenings begin to lose some humidity, producing clearer skies at times. The desert’s heat is best handled by early starts for activities like sandboarding. If you’re planning a Nazca lines flight, early morning departures reduce thermals and provide the clearest viewing.

Southern Coast & Nazca Plateau (Nasca, Arequipa lowlands)

March’s warmth persists with clear skies that make early-morning Cañón del Colca drives especially crisp; afternoons in Arequipa may feel quite hot in low-lying districts. This is a good month for combining Colca Canyon trekking with city sightseeing because the higher-altitude trails are still dry. Bring sun protection and a light layer for cool evenings in the canyon rim towns.

Northern & Central Highlands (Huaraz, Cajamarca, Ancash)

March shows a slow reduction in storm frequency though afternoons still commonly bring showers and localized flooding in valleys such as Santa and Conchucos. Trails regain some of their summer greenery but stay slippery; waterfalls are at their most dramatic if you don’t mind wet feet. Guide services remain active but recommend caution on high-altitude treks until the dry window consolidates.

Cusco & Southern Highlands (Cusco, Sacred Valley, Puno, Colca)

March still shows substantial rain with the landscape at its greenest and river levels high; Colca Canyon waterfalls are powerful and spectacular. Afternoon thunderstorms can arrive suddenly in Cusco, so schedule morning explorations of archaeological sites and museums. Taxi and bus journeys sometimes delay due to poor road conditions - build float days into tight itineraries.

Amazon Basin (Loreto, Madre de Dios & Manu)

March keeps the basin hot, humid and rainy with atmospheric moisture making jungle walks steamy; rivers begin to crest in many sectors. Lodges accessible only by road (in drier years) may be cut off, so most ecotourism shifts to boat-based activities. For photographers, reflective water scenes and swollen waterfalls can produce fantastic images, though heavy spray and humidity demand waterproof protection for gear.
