Though famous for rain, Sao Paulo boasts a pleasant climate and enjoyable weather year-round. Classified as having a humid subtropical climate under the Köppen system, its weather mirrors that of Rio de Janeiro, only slightly cooler, as it is inland and not on a plateau. The average temperature for the city is 65 degrees Fahrenheit (18 degrees Celsius), but the humidity, ranging from 74 to 80 percent throughout the year, can make it feel hotter.

Because Sao Paulo has a mild, warm, and temperate climate, seasons are not well-defined and rainfall is one of the main distinguishing factors between them. (Sao Paulo receives about 52.8 inches of rainfall per year). Winters are dry and cool with little rain, while the spring has lots of sunny days and ranges in temperature from 54 to 76 degrees F (12 to 24 C). In summer, temps rise into the high 70s Fahrenheit, rain and humidity increases, and flash thunderstorms occur. Fall has drizzly days, and temperatures begin to cool, dropping down to what they were in the fall.

As Sao Paulo is located in the Southern Hemisphere, seasons are opposite of the Northern Hemisphere’s, meaning summer begins in December and stretches through February. Those wanting to avoid the rain should come during the driest (though still rainy) time of the year from April to September. However, for those planning on going to the nearby beaches, summer will be best, when temperatures are highest.

Fast Climate Facts

  • Hottest Month: February (71 F / 22 C)
  • Coldest Month: July (60 F / 16 C)
  • Wettest Month: January (9.3 inches)
  • Most Humid Months: January, March, April, and December (80 percent)

Flash Thunderstorms and Flooding

Every year, Sao Paulo has flooding in different parts of the city. This is especially common during the summer (the wettest season) when temperatures rise and deluges of rain can fall on the city in a flash thunderstorm. While global warming and climate change play roles in this, problems with the city’s drainage system, as well as the massive swaths of concrete and asphalt covering the city, also contribute to the flooding. Subway stations get shut down, streets become undrivable, and in some of the more extreme cases, people have had to be rescued with jet skis. Should a massive thunderstorm occur, it's usually best to wait to go outside until the rain subsides and the streets can drain a bit.

Winter in Sao Paulo

Winters are mild, and though the temperature can dip into the low 50s Fahrenheit, the city still experiences days with highs in the low 70s. This is especially true during a few days in August when the city experiences the verãozinho (little summer) when a bout of hot, dry weather sweeps into town. This is the driest and least humid season in Sampa, as well as the high season for tourism (with hotel prices reflecting that). Paulistanos and visitors can soak up plenty of Vitamin D, as July is the sunniest month of the year. Even with the occasional warm day and loads of sunshine, the cold days can feel surprisingly cool indoors, as many of the city’s buildings don’t have heating.

What to pack: Bring jeans, T-shirts, tank tops, and shorts to mix and match for varying temperatures, as well as a light jacket or sweater. Sunblock and good walking shoes are key for touring around the city. If you’re planning on visiting one of the city's upscale bars or restaurants, pack at least one fancy outfit.

Spring in Sao Paulo

Sao Paulo begins to heat up with temperatures climbing to the mid-70s, and city residents head to the nearby beaches of Santos, Praia Grande, and Ilhabella. The city hosts massive events, drawing international audiences for Sao Paulo Fashion Week, the Sao Paulo International Film Festival, and the Formula 1 Grand Prix Race. If coming during the festivities, book accommodation well in advance. The humidity picks up slightly, as does the rain, however, the weather is generally sunny and pleasant and daylight hours increase throughout the season.

What to pack: Take lightweight, airy clothing like dresses and loose shirts. Shorts and flip flops are musts, as are a hat and a swimsuit if hitting the beaches. Sunblock, a light raincoat, and a jacket will cover all the weather variations. Also, bring some fancy outfits for going out, especially if attending Fashion Week.

  • September: 73 F / 54 F (23 C / 12 C)

Summer in Sao Paulo

The longest days of the year arrive, and revelers dance in the streets for Carnival. Residents continue to head out of town to regional beaches like Santos, where the seawater temperature ranges from 73 to 80 degrees F (23 to 27 degrees C). Sao Paulo itself heats up to the high 70s, and the humidity increases to 80 percent. Rains are more of a concern than the wet heat, as summer is the rainiest season. Flash downpours can occur, flooding roads and causing epic traffic jams.

What to pack: Tanks tops, swimsuits, sunblock, shorts, and any lightweight clothing are all essential Sao Paulo summer items. Sunglasses and billowy shirts and skirts will work for both the city or a day beach getaway as well. Pack waterproof shoes, a raincoat, and a good umbrella.

Fall in Sao Paulo

Days stay sunny and nights begin to get cooler. Daylight hours begin to decrease steadily each month, but there’s still plenty of sunshine to enjoy outdoor activities like the annual Virada Cultural, the world’s largest 24-hour festival showcasing music, film, and other art forms held in May. Humidity levels are the same as in the summer months, hovering around 80 percent. The first part of fall is rainy, with March averaging 6.3 inches of rain for the month, but April precipitation drops to just 2.9 inches. Thankfully, this season has plenty of indoor events non-weather-dependent, like the Sao Paul Restaurant Week, taking place in over 100 of the metropolis’ best restaurants, and the Biennial de Sao Paulo, one of the most important art events in the world housed inside an exhibition space in Ibirapuera Park.

What to pack: Bring T-shirts and shorts for the day, jeans and a jacket for the night. Take sunglasses and rain gear for the fluctuating weather, and pack a pair of good walking shoes, as many major events happen in multiple locations.
