The coldest month is January: the Po valley's mean temperature is between −1 and 1 °C (30 and 34 °F). Winter morning lows can occasionally reach −30 to −20 °C (−22 to −4 °F) in the Alps and −14 to −8 °C (7 to 18 °F) in the Po valley, with records close to −30 °C (−22 °F) near Bologna are some of the coldest winters. Summer is usually more stable, although quite stormy near the Alps, with July temperatures are 22–24 °C (72–75 °F) north of river Po, like in Milan or Venice, and south of river Po can reach 24–25 °C (75–77 °F) like in Bologna.
