Asuncion Weather in December

December weather

December in Asunción is hot, humid summer weather. Afternoons can feel sticky, and rain falls on many days, often interrupting plans. The high is 33°C, with 169 mm of rain across 13 days. November is rainier, while January is hotter.

Sightseeing works better in the morning, before the heat settles over the historic centre. Save museums and shaded café stops for the afternoon, then stroll along the Costanera by the Paraguay River when it cools. Heavy showers can make long outdoor walks uncomfortable, so don't build your whole day around them.

Christmas in the city

Christmas and New Year bring local celebrations, church services and family gatherings. You'll see decorations around the city, though Asunción's December calendar is quieter than its major festival periods. Some businesses may close or change hours around the holidays, so keep your plans flexible.

For families, shorter outings to places such as the botanical garden are easier than trying to sightsee through the hottest part of the day.

Crowds and local tips

December is part of the summer holiday season, so local families may be travelling and popular spots can feel busier around Christmas and New Year. It's generally a higher-season month than June to September, Asunción's more comfortable travel period; expect stronger demand and potentially higher prices for stays and transport.

For a useful local break, visit Mercado 4 in the morning, when browsing its stalls is less draining. Try sopa paraguaya, a savoury corn-and-cheese dish, at a market food stall. Take a taxi back if rain is falling heavily: wet streets and the afternoon heat make a long walk less pleasant.
