Campo Grande, the capital of Mato Grosso do Sul state, sits inland on a plateau in central-west Brazil at around 530 metres above sea level, near the vast Pantanal wetlands, at approximately 20.44°S, 54.65°W. It has a tropical savanna climate (Köppen Aw) — warm year-round — with a wet summer and a drier winter, and its interior position brings occasional sharp cold snaps sweeping up from the south. Being in the Southern Hemisphere, its seasons are reversed relative to the Northern.
Summer, from October to March, is hot and the rainy season, with highs around 31–33°C and warm, humid nights, occasionally climbing higher in humid heat. This is when most of the year's rain falls, in heavy afternoon and evening thunderstorms, and the combination of heat and humidity can feel oppressive on the plateau near the Pantanal.
Winter, from June to August, is warm and drier by day, with highs around 26–28°C, but it is punctuated by the friagem — sudden cold winds sweeping up from the far south that can abruptly drop temperatures to around 5–10°C for a day or two, bringing grey, chilly, damp weather that contrasts sharply with the surrounding warmth. Rain is much reduced.
Campo Grande receives on the order of 1,400–1,500 mm of rain a year, concentrated in the summer wet season from October to March, when heavy thunderstorms are frequent; the winter from June to August is markedly drier. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Campo Grande's most distinctive weather event is the friagem, the cold southerly wind that periodically surges up from Patagonia to interrupt the tropical warmth with sudden sharp cold snaps, most often in winter. Otherwise its plateau setting near the Pantanal gives it a hot, humid, thundery wet season and a drier, warm winter, with the seasonal rains driving the flooding of the nearby wetlands.
