Peru is the kind of country that makes climate feel personal. You can land in Lima and wonder why a “desert city” feels damp and gray, then fly to Cusco and realize the sun is strong but the nights bite. That is not bad luck. It is geography doing its thing: a cold ocean current hugging the coast, a mountain range that forces air to rise and cool, and tropical moisture on the Amazon side that fuels a totally different weather engine.
World Climate Day is the perfect moment to explain Peru because climate is not abstract here. It shows up in what you pack, when you hike, how you schedule Machu Picchu, and even how your body feels during your first days at altitude.
