Is July a Good Time to Visit Lima?
July is a fair time to visit Lima (5/10). Average highs of 17°C and 1 sunshine hours daily make conditions workable, though not exceptional. Culture-focused travellers and those who prefer lighter crowds will find July a practical choice, with prices running lower than peak January without sacrificing all the good weather. August offers a similar profile at lower hotel rates if dates are flexible. The main practical note: Lima's popular sites are busiest between 10am and 3pm regardless of season. Arriving at opening time or after 4pm makes a significant difference to the experience. Planning tips: accommodation is generally available without long lead times, and flight prices are typically lower than peak season. Flexible travellers will find the best deals by booking 2-4 weeks ahead. Mid-week arrivals consistently unlock lower hotel rates than weekend check-ins.
Based on 30-year climate normals (1991 to 2020), July in Lima averages 17°C by day and 9°C overnight, a range that places it in the temperate middle ground of the year.

What to Wear in Lima in July
Packing for Lima in July means dressing for 17°C days and 9°C evenings. A mid-weight jacket over a sweater handles 17°C daytime temperatures; the combination stays comfortable all day without overheating. Evening temperatures settle at 9°C, a modest 8°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. At 75% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
Local tip: Layers are more practical than a single heavy garment in Lima. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.
Events in Lima in July

Climate data: Open-Meteo ERA5 (1991–2020).
