Climate - Santa Fe (Argentina)

The climate of Santa Fe de la Vera Cruz is subtropical, with mild, quite dry winters and hot, rainy summers. In summer, the rains often occur in the form of thunderstorms.
The city is located in north-central Argentina, on the eastern edge of the Pampa, on the banks of the Salado del Norte River, which then flows into the Paraná south of the city. A short distance away is the city of Paraná, across the river of the same name, which flows a few kilometers to the east.
We are in an area where the waters of the rivers have created some lagoons over the centuries. The closest to Santa Fe is the Setúbal lagoon.
As a result of very heavy rains, the waters of the rivers can flood part of the city, as happened in April 2003 and March 2007.
