Cochabamba, Bolivia's fourth-largest city, sits in a fertile valley of the Andean Cordillera Oriental in central Bolivia at around 2,560 metres above sea level, at approximately 17.39°S, 66.16°W. Its intermediate altitude gives it a mild subtropical highland climate (Köppen Cwb) — warm, spring-like days year-round — earning it a reputation for near-perpetual pleasant weather, with the year divided into a summer wet season and a winter dry season.

There is little seasonal temperature change: days are warm and spring-like year-round, with highs generally around 25–27°C. The warmest, driest spell comes in spring before the rains, around September to November. The wet season, roughly December to March, brings frequent afternoon showers and thunderstorms that green the valley, with daytime temperatures easing slightly under the cloud, while nights stay mild.

The dry season, from May to August (the local winter), brings warm, sunny, dry days around 24–26°C but noticeably cooler nights that can drop close to freezing on the clearest nights, giving a wide day-to-night swing. Rain is scarce, skies are clear and bright, and this dry, sunny stretch is very pleasant by day, though a warm layer is needed after dark.

Cochabamba is fairly dry, receiving on the order of 450–500 mm of rain a year, strongly concentrated in the wet season from December to March, when most of the year's rain falls as afternoon thunderstorms; the long dry season from May to September sees very little. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Cochabamba's sheltered Andean-valley setting and moderate altitude give it the mild, sunny, spring-like climate for which it is famous — warm days, cool nights and abundant sunshine most of the year, the reason it is sometimes called the 'City of Eternal Spring'. The clear division between a green, thundery summer wet season and a dry, bright winter, together with the large day-to-night temperature range, defines its weather.
