How humid is Peru in 2026?

Lima and neighbouring coastal districts often sit near roughly 80% relative humidity for long stretches, especially under garúa from about May through November: Living in Lima. The air feels damp and cool even when daytime highs hover near the mid-teens to low twenties Celsius. Clothes dry slowly, windows stay wet, and unheated flats feel colder than the number suggests. December through March usually brings more sun and warmer afternoons, yet coastal moisture never fully disappears.
