Peru Lima Weather in August — Climate Guide
August in Lima is moderate
August is moderate for Lima.
August closes out Lima's garúa peak — 19°C highs, 14°C nights, 87% humidity (year's highest). Sunshine still 3 hours. Korean traveler density tapers from July's peak but August 15 (Korean Liberation Day) creates a minor secondary spike. Santa Rosa de Lima on August 30 (Lima's patron saint, national holiday) brings religious processions to Centro Histórico — the Santuario de Santa Rosa receives 200,000+ pilgrims throwing wish-letters into a stone well. Cusco peak season holds — Inca Trail permits fully booked, Machu Picchu daily entry capacity (4,500) often hits noon. Lima continues to be a 2-3 day foodie stop within a Cusco-led itinerary.
