Temperature in Rio de Janeiro in July

The 8°C day-night temperature range is typical for continental climates: a light jacket in the morning that you shed by midday and need again after sunset. At 78% humidity, the 25°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. The UV index of 2 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Winds are calm at an average 11 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 77°F average high, 63°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).

Packing for Rio de Janeiro in July means dressing for 25°C days and 17°C evenings. A light cotton tee with a casual overshirt works well at 25°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 17°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 78% 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 Rio de Janeiro. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.

Why is Rio de Janeiro warm in July?

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

Sunshine Hours

The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.
