What to expect in Diamantina in September

Editor's tip

September is spring in Diamantina. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 24.5 °C (76 °F) and nights that still call for a light jacket. Crowds sit somewhere in the middle, with peaks on public holidays. Outside those dates, you can enjoy the place at an easy pace and spend less. It also rains very little: this is one of the driest months of the year, good for anyone who wants an outdoor itinerary. If the dates line up, it is worth fitting Vesperata into your itinerary: it is what livens up the destination at that time of year.
