Sao Paulo is a concrete jungle on a high plateau among sub-tropical forest covered mountains. Because of the increase in pavement and concrete accompanying the growth of this megalopolis, the city has become hotter.

As the sun heats up the city during the day be prepared to peel of the warmer clothes you needed as you left your hotel in the morning. Because of the mountain climate the nights are usually cool for those not liking to sleep in air-conditioning. Of course for those of you who prefer air, it's prevalent in all fine hotels.

Like most sub-tropical climates there are often passing summer showers at the end of the afternoon. This is the rainy season in Brazil. In the winter, though one could hardly call it winter based on European or North American standards, it doesn't rain much as it's the dry season.
