During the daytime, you can generally expect temperatures to range from the low 20s to the mid-20s Celsius (mid-70s Fahrenheit). This makes it comfortable to wear light clothing, such as short-sleeved shirts, blouses, and lightweight pants or skirts.

At night, the temperature in São Paulo cools down, with average lows around 14°C (57°F). While this isn't extremely cold, it's cool enough to warrant warmer clothing. A light jacket, sweater, or even a light scarf can be helpful in staying comfortable during the evenings, especially if you plan to be outdoors.

It's also worth noting that while the average temperatures provide a good general guideline, there can be occasional variations. Some days may be warmer than average, with temperatures climbing closer to 27°C (80°F) or higher.
