Updated: March 2026
February is a fair time to visit Rio de Janeiro (5/10). With 10 daily sunshine hours and only 17 rain days, this month delivers genuinely reliable outdoor conditions, ranking it 2nd sunniest of the year in Rio de Janeiro. Culture-focused travellers and those who prefer lighter crowds will find February a practical choice, with prices running lower than peak January without sacrificing all the good weather. Rio Carnival takes place this month, adding cultural value for those planning around it. Watch out for prolonged rain stretches: with 17 wet days, a fully outdoor itinerary is risky. Build in museum days and covered market visits as contingency. 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.
Visiting Rio de Janeiro in February means bold, midsummer heat topping 30°C. Factor in 17 potential rainy days and 78% average humidity when planning your daily activities.

The 7°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 31°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. UV index averages 9 this month, classed as high to very high. SPF 30+ sunscreen, a brim hat, and sunglasses are not optional between 10am and 4pm. Winds are calm at an average 11 km/h, so wind-chill is not a factor in planning your clothing. In Fahrenheit: 88°F average high, 75°F overnight low. Data sourced from Open-Meteo ERA5 climate reanalysis (1991–2020 normals).
Packing for Rio de Janeiro in February means dressing for 31°C days and 24°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 31°C daytime heat. Evening temperatures settle at 24°C, a modest 7°C drop that a light cardigan or denim jacket covers. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. With 17 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: Rio de Janeiro sees heavy rain periods where a compact travel umbrella can feel inadequate. A packable waterproof jacket offers better coverage for prolonged downpours and leaves both hands free for maps and cameras.
Week before Ash Wednesday
The world's largest carnival. The Sambadrome parade is the centrepiece, but neighbourhood street parties (blocos) run for weeks. Book accommodation 6 to 12 months ahead.
Rio de JaneiroBased on 31°C average highs and 17 rainy days
Rio de Janeiro's February climate is governed by the Inter-Tropical Convergence Zone (ITCZ), which draws moisture-laden trade winds across the region, producing the characteristic wet season rainfall of steamy tropical cities. Daytime heat peaks around 31°C, moderated slightly by afternoon convective showers. Overnight temperatures remain warm at 24°C because the humid air retains heat effectively. 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.
UV Index
A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate, wear sunscreen. UV 6-7: High, hat and SPF 30+ essential. UV 8-10: Very High, limit midday exposure. UV 11+: Extreme, seek shade between 10am-4pm.
Rain Days
A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.
Humidity
Relative humidity as a percentage. Below 40%: Dry, skin and throat may feel parched. 40-60%: Comfortable, ideal for most people. 60-80%: Sticky, light breathable fabrics recommended. Above 80%: Muggy, heat feels more intense; quick-dry clothing is essential.
