The Brazilian summer officially runs from December 15 to March 15. February, the month of carnival, falls square in the middle of the Brazilian summer. This means that Salvador will be HOT when you get here and more than likely “sticky,” the air thick with humidity. Temperatures range from a low of 23C/73F to highs of 35C/95F, but due to the humidity, it can "feel" much hotter.
Complicating matters, for those arriving straight from the northern heights of the USA or Europe, you’ll be trading “mid winter freeze” for “deep summer hot.” While this sounds like a winning trade on paper, the first 24 to 48 hours can be rough as your body makes this dramatic adjustment. Hang in there, don’t panic; after your body acclimates, you won’t miss the snow and ice back home.
The good new is that since Salvador is a peninsula between ocean and bay, evenings are generally cool, with a refreshing breeze.
