Best times to post on social media from São Paulo, Brazil 🇧🇷

It depends entirely on where your audience is, not on São Paulo. Peak posting hours are measured on the audience's clock, so the answer is their peak hour converted into São Paulo time (GMT-3).

São Paulo, Brazil runs on America/Sao_Paulo, currently GMT-3.

The audience's peak hour does not move, but what it reads as on your clock in São Paulo does, and for a week or two each spring and autumn the usual difference is an hour out, because not every country changes its clocks on the same date.

São Paulo, Brazil runs on America/Sao_Paulo (GMT-3), so every time in the table above is what your own clock will read. Peak posting hours are published in the audience's local time, which makes the only figure that matters to you a straight conversion, with two traps: the offset is not a whole number of hours everywhere, and two places do not necessarily change their clocks on the same date.

Of the 11 audiences in the table above, 4 have at least one platform whose peak hour falls on a different calendar day in São Paulo. That is the mistake that costs a whole post, and it is why the day name sits next to every converted time. Converted times use the offsets in force this week (GMT-3). The audience-clock column never changes; the converted column is rebuilt weekly so it stays right across daylight-saving changes.
