Weather in Brazil
 

About to head off to Brazil for the next two weeks. I'll be in Sao Paulo, Rio, Manaus and the Iguaçu Falls.

Anyway, it's looking like rain, rain and more rain. I thought that we are nearing the end of the rainy season so I'm wondering how bad will it be?

Should we mostly bring pants or will it be warm enough for shorts?

Any info would be appreciated as well as any comments for those of you who are around any of those areas right now.

It's not as bad as it seems. Here in Minas Gerais we have a drought in the middle of the wet season. I can't think of what the dry season will look like.
Anyway, even in the proper rainy season it doesn't rain every day, or all day. On the plus side, from the news, Iguaçu Falls are full with water, so they will be nice to see.

In Rio and Manaus you can use shorts year round, even during winter (winter in the North and Northeast regions are popularly defined not by cold weather, but by rains).

São Paulo and Iguaçu Falls become colder during winter, but it is highly improbable that you will encounter cold weather right now, only rain.

Bring mostly shorts and hedge it with a few pants.

Thank you two for the info! Hopefully it won't rain so much we won't be able to get out and really explore the cities.

My wife and I each take a small travel umbrella this time of year, which packs easily enough.

Sampa, as mentioned can be a different story in the Winter. One pair of good comfortable pants should be sufficient.

Umbrellas, really large ones that actually protect you from the rain, can be purchased on every block in Rio and other cities for about R$10 (U$5). It is likely to be too hot everywhere you mention for a jacket. If you bring one pair of long pants, do bring very, very lightweight ones, in cotton or linen (natural fibers); jeans or even khakis would be much too heavy unless you currently live in a very hot climate where you are used to wearing them in heat/humidity.

You're talking about an area not much smaller than the continental USA, so the weather is different, depending on where you go. Unless you're going to the south - Sao Paulo and further south - in the June-August timeframe, stick to shorts and t-shirts.

The weather was a bit unpredictable in Rio last week, and it rained off and on, but even though the forecast said possible thunderstorms, they did not materialize most days. Same for Foz de Iguaçu. Even with rain, Rio and Iguaçu were warm and humid

My wife, a doctor in Fortaleza, always recommends wearing long pants in the evening as protection against mosquitoes, though the skeeters that carry dengue can be active during the day. Manaus often humid if not rainy, and warm to hot. I would always have long pants, in additiont o shrots, in Rio, SP, etc. Good point on umbrellas. If you get any sort of wind with the rain, the small travel umbrellas don't always do much good (you may see several discarded on the streets).

If it's a drizzle you don't need an umbrella. If it's a downpour, an umbrella won't protect you. When it's warm, it doesn't matter if you're wet because of sweat or wet because of rain :). That's just IMO. :)
