Concepción has a tropical savanna climate (Köppen: Aw) with abundant annual precipitation, although possessing a highly prominent summer peak. Summers are very hot, rainy, and often oppressively humid. Severe thunderstorms are very common in the summer and have the capability to dump copious amounts of rainfall in a short period of time, along with destructively high winds and occasional hail. Winter is much drier and considerably cooler, with near drought-like conditions often prevailing. Concepción is also located in very close proximity to the Tropic of Capricorn, with the latitudinal line lying just south of the city.
