Vejret i Brasília i december

Forum posters describe Brazil's summer months, December through March, as bringing both higher temperatures and more rainfall generally, with January and March both cited as hot and capable of getting genuinely rainy. One visitor's Brasilia-specific report described three very nice, hot days followed by an hour of pouring rain before conditions cleared again - a pattern posters describe as typical of the Brazilian south/southeast more broadly, where strong late-day showers are common but all-day, ceaseless rain is not. Posters also note that January rain often falls in concentrated torrential bursts, sometimes overnight, delivering in a single night what might otherwise spread across a month of lighter drizzle elsewhere. Posters generally rate January as hot and genuinely rain-prone for Brasilia, with the rain itself typically confined to a dramatic but short daily window rather than an all-day washout.

The dry season runs roughly May through October/November, and forum posters describe July conditions as hot and very dry with humidity often under 20% - genuinely dusty at times. July also falls in school holidays, so nearby attractions draw more crowds than the shoulder months. One upside repeated on the forum: the dryness makes it easy sightseeing weather, and Chapada dos Veadeiros - waterfalls, canyons, long hikes - is an easy trip from the city if you want a change from the capital's modernist architecture.
