About Arequipa weather

Arequipa is in Provincia de Arequipa, Peru at -16.40°, -71.54°. Right now it’s 13° and clear; today’s high is 15° with a 0% chance of rain.

Peru's geography creates three dramatically distinct climate zones. The coastal desert strip along the Pacific is arid and cool, heavily influenced by the cold Humboldt Current that suppresses rainfall and creates a persistent marine fog layer called garúa during winter months (May-November). Lima, despite being near the equator, receives almost no rain and is one of the driest capital cities in the world.
