At the southern end of Buenos Aires province, "Bahía Blanca is on the final limit of this pampa, when the first gentle slopes announce the north of Patagonia, with elevations between 200 and 500 m., except in Sierra de la Ventana that reaches 1200 m.
The proximity of the sea confers unique characteristics to the coasts that face the wind as a proverbial visitor. You will note how the weather varies while you separate from the coast and enter into Patagonia, turning from moderate into dry and more windy."
