Quito is in a unique situation among cities, as it is one of the few cities located on the equator and it is the only city on Earth in which the climate changes depending on what hemisphere the place is in, in the Southern Hemisphere (which the vast majority of Quito falls under), the city has a subtropical highland climate, while in the Northern Hemisphere, the city has a warm-summer mediterranean climate.
Because of its elevation and proximity to the equator, Quito has a fairly constant cool climate. The annual average temperature is 15.6 °C (60.1 °F). The city has only two seasons: dry and wet. The dry season, June through September (4 months), is referred to as summer; the wet season, October through May (8 months), is referred to as winter. Annual precipitation, depending on location, is about 1,000 mm (39 in).
