As of 2026, Lima in May averages a high of 23°C and low of 16°C with 2mm of rain over about 2 days. Garúa fog season starts — long-sleeve shirts, light pants, waterproof-shell jacket for drizzle. Layered for 7°C day-night swing. Closed shoes mandatory. UV drops to 7 (moderate), sunscreen still recommended for sustained outdoor time.
May is good for Lima.
May marks the transition into garúa season — Lima's defining 7-month stretch of cool, gray, occasionally drizzly weather caused by the Humboldt Current colliding with Atacama desert edge. Daily highs drop to 23°C, mornings start foggy until 10-11, and afternoons sometimes clear briefly. This is paradoxically when international foodies arrive in force — May is when World's 50 Best Restaurants list publishes, and Central / Maido / Kjolle bookings surge based on rankings. The flip side: Cusco enters peak dry season (best Inca Trail conditions), so May-September is the most popular Peru combo window. Korean travelers planning a Cusco-first itinerary should consider May for that reason, accepting Lima's garúa as the trade-off. Hotels in Miraflores drop 30-40% versus February peak.

May Travel Advice
Plan Lima as a 2-day foodie stop within a Cusco-led Peru itinerary this month — Cusco's dry season opens and Inca Trail is at its best (4-day permits, $700-900). Lima activities should favor indoor culture (Larco Museum open till 22, MATE in Barranco, Casa Aliaga colonial mansion). If garúa frustrates you by day 2, pivot to Pisco distillery tour in Ica (3h south) or Pachacamac ruins (1h south, often clearer than Lima). Central / Maido reservations open 2-3 weeks ahead as international demand peaks post-World's 50 Best announcement.
Flying In from Overseas
North American spring travel peaks; European late-spring shoulder begins. South American visitors thin. Direct flights moderate: Lima NYC 8h ($480-850), LAX 8h ($450-800), Miami 5.5h ($380-750), Madrid 12h ($700-1,250). Korea via LAX 24-28h ($1,400-2,200) — Korean travelers favor May for Cusco timing. Japan via Houston 26-30h ($1,800-2,700). Australia direct via Santiago 22-26h ($1,700-2,500). World's 50 Best Restaurants announcement (typically late May) drives Central / Maido / Kjolle bookings.

Shoulder pricing: Belmond Miraflores Park $350-1,000, JW Marriott $250-500, Hilton $180-400, Hotel B $300-700, Country Club $250-500.
