Temperature in Rio de Janeiro in April

The 6°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.

UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Winds are calm at an average 11 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 82°F average high, 72°F overnight low.

Packing for Rio de Janeiro in April means dressing for 28°C days and 22°C evenings. A light cotton tee with a casual overshirt works well at 28°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 22°C, a modest 6°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. With 14 rain days expected, a compact travel umbrella is worth the bag space. A waterproof jacket is better than an umbrella if you plan full-day outdoor routes. 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.
