Peru weather overview

Peru is a large country, twice the size of France, with a long, narrow Pacific coastal plain, the high Andes mountains - which include a substantial area of high plateau - in its interior and a region of low-lying rainforest in the Amazon Basin.

The coastal plain, which has Lima at its centre, has a desert-like climate with just minimal rainfall throughout the year. Here the cold offshore Humboldt Current plays a key role by producing a lot of cloud and mist which obscures the sun and prevents temperatures from rising.

In the mountains, it's a different story: temperatures drop lower the higher up you go. The slopes of the Andes are semi-tropical but, on higher ground, night time temperatures can be extremely cold and frosts are frequent during the dry season. The high peaks are permanently snow-capped.

On the Andean plateau, rainfall is low and occurs mainly from December to March. The two main hazards you'll encounter here are altitude sickness and sunburn: the air is very thin at 3,000m (10,000ft), so you should be prepared to acclimatise slowly.

The lowlands to the east of the Andes have a hot, steamy equatorial climate with a single heavy rainy season from November to February when temperatures are highest.

What to pack for Peru weather

Pack light cotton clothing plus rainwear for the Amazon Basin, warmer clothes for the evenings and winters on the coast and much warmer clothing for the mountains.
