Mantua sits in the Po Valley of northern Italy, giving it a humid subtropical climate (Cfa) with four distinct seasons. Summers are hot and sticky, with July and August averaging highs of 30°C (86°F) and humidity levels that can make it feel several degrees warmer. Winters are cold and damp, with January lows dropping to -1°C (30°F) and frequent fog that blankets the city for days at a time. The three artificial lakes surrounding Mantua moderate temperatures slightly compared to inland Po Valley cities, but they also add to the humidity. Spring and autumn are the most pleasant seasons, with mild temperatures, lower humidity, and the best conditions for walking between the Ducal Palace, Palazzo Te, and the lakeside paths. For a complete overview of the city, see our Mantua travel guide.

January and February: Cold, Foggy, and Quiet
January is the coldest month in Mantua, with average highs of 6°C (43°F) and lows dipping to -1°C (30°F). Thick fog is common, sometimes persisting all day and reducing visibility to less than 100 metres. The city sees about 7 rainy days and around 55mm of precipitation. February brings a slight improvement with highs reaching 9°C (48°F) and marginally less rain at 45mm, but the fog remains a factor. These are the quietest months for tourism, meaning you will have the Ducal Palace almost to yourself. Pack a heavy coat, scarf, gloves, and waterproof shoes. The lakeside paths can be muddy and slippery. To pick the best month for your trip, check our guide on the best time to visit Mantua.
March and April: Spring Awakens
March sees temperatures climb to 14°C (57°F) during the day, though nights stay chilly at 5°C (41°F). Rainfall increases to 55mm across 7 days. April warms further to 18°C (64°F) highs and 8°C (46°F) lows, but it is also one of the wetter months at 70mm over 9 days. By April, the wisteria and magnolia trees in the city gardens begin blooming, and outdoor cafe seating returns to Piazza delle Erbe. Pack layers: a light jacket or trench coat, an umbrella, and comfortable walking shoes for the cobblestone streets. For sightseeing ideas, browse our list of things to do in Mantua.
May and June: Warm and Lush
May is one of the best months to visit Mantua. Highs reach 23°C (73°F), lows hover at 13°C (55°F), and you get 8 hours of sunshine daily. Rainfall peaks at 75mm over 9 days, but it tends to come in short afternoon showers rather than all-day drenchings. June heats up to 27°C (81°F) with 9 hours of sunshine and 65mm of rain. The lakes are green and full, the parks are lush, and the evenings are perfect for dining outdoors along the Rio, the canal that cuts through the old town. Pack light clothing, sunscreen, and a light sweater for evenings. Plan around major events with our Mantua events and festivals calendar.
July and August: Hot, Humid, and Crowded
July is the hottest month with highs of 30°C (86°F) and lows of 19°C (66°F). Humidity levels regularly exceed 70%, making it feel closer to 35°C (95°F). Rain drops to 50mm across 6 days, and you can expect 10 hours of sunshine. August is nearly identical at 29°C (84°F) with 65mm of rain. The Ferragosto holiday (August 15) sees many local businesses close for a week or more, though tourist attractions remain open. The lakes provide some relief with breezes, and air conditioning is standard in hotels and museums. Pack the lightest clothing possible, a hat, high-SPF sunscreen, and mosquito repellent. The lakes breed mosquitoes in summer, and they can be aggressive at dusk. To decide where to base yourself, read our Mantua neighborhoods guide.
September and October: Golden Autumn
September cools to a pleasant 25°C (77°F) during the day, with nights at 15°C (59°F) and 70mm of rain across 7 days. This is the start of the Festivaletteratura (Literature Festival) season, typically held in early September, drawing book lovers from across Europe. October drops to 18°C (64°F) highs and 9°C (48°F) lows, and it is the wettest month of the year at 85mm across 8 days. The fog begins returning by late October. The autumn colours along the lakes are spectacular, and the lower tourist numbers mean shorter queues at Palazzo Te. Pack a waterproof jacket, layers, and sturdy shoes.

November and December: Fog, Chill, and Christmas Markets
November is cold and grey, with highs of 11°C (52°F), lows of 4°C (39°F), and 80mm of rain across 8 days. The fog settles in seriously this month and can last for days without breaking. December brings similar temperatures with highs of 6°C (43°F) and lows around freezing. Rainfall is 55mm across 7 days, occasionally falling as light snow (though accumulation is rare, maybe once every 2 to 3 years). The Christmas markets in Piazza Sordello and Piazza delle Erbe run from late November through December 24, with mulled wine, local crafts, and roasted chestnuts. Pack a heavy winter coat, warm layers, hat, and gloves. For practical information, read our Mantua travel tips.
