Curitiba Weather in December

December weather

December feels warm, damp and often cloudy in Curitiba. Highs reach 27°C, but evenings are milder, with lows around 16°C. Rain falls on 21 days, so showers can interrupt a day out; the month gets 165 mm. There's plenty of daylight, but sunshine averages just 3.6 hours a day.

The weather suits a flexible city break. Visit the Oscar Niemeyer Museum or browse cafés around Batel when rain sets in, then stroll through the Botanical Garden during a dry spell. Long hikes are less appealing when trails are wet and skies are cloudy. If you hate crowds, choose indoor sights on rainy afternoons rather than joining everyone beneath the same small shelter.

Christmas and summer crowds

Curitiba's Christmas programme brings seasonal lights and performances around the city. The choir at Palácio Avenida, in the city centre, is a well-known annual tradition, though schedules can change. Christmas and New Year also fall during Brazil's summer school holidays, when families travel and demand rises.

Expect more visitors and potentially higher prices than in quieter months. December is warm and wet, while May and July to August are among the better months overall for weather. January is just as warm and wetter, with 209 mm of rain, so December isn't the rainiest summer option.

Make rain easier

Keep a covered stop in mind near the places you want to see. The Oscar Niemeyer Museum works well as a rainy-day plan, and its distinctive eye-shaped building is easy to spot. For a dry spell, take the bus to the Botanical Garden and see its glass greenhouse; the gardens are less fun when paths are slick.

Travelling with kids? Pair the greenhouse with a nearby indoor stop, rather than counting on a full afternoon outside. Check the Christmas event details locally before setting out, since performances and light displays can shift from year to year.
