Mantua Geography & Climate

Mantua lies on the Po plain at about twenty metres above sea level, on a loop of the Mincio, which drains Lake Garda southwards to the Po. In the twelfth century an engineer dammed the river to form three shallow lakes that surround the city on the north, east and west, turning it into a near-island and solving its defence.

A fourth lake existed to the south until it was drained in the eighteenth century, which is where the marshy ground around the Palazzo Te comes from.

The lakes are shallow, slow and rich in life. They carry one of Europe’s larger stands of lotus, introduced in the 1920s and now flowering across the Lago Superiore in high summer, and the surrounding wetlands are a regional park with substantial birdlife — herons, egrets and cormorants are ordinary sights from the city itself.

The land beyond is entirely flat, intensively farmed for cereals and dairy, and prone to fog in winter and haze in summer.

Mantua has a humid subtropical climate of the Po basin type. Summers are hot and heavy, regularly in the low to mid thirties Celsius, and the lakes raise the humidity noticeably — mosquitoes are a genuine feature of summer evenings here.

Winters are cold and damp, often between minus two and six degrees, with frost frequent and fog persistent; the lakes can freeze at the edges. Snow is occasional rather than reliable.

Spring and autumn are short, mild and the best of it. The lotus on the Lago Superiore flowers roughly from July into August, which is the one thing worth tolerating the summer humidity for.
