🇲🇩Moldova

Moldova spans 45°28′–48°29′N as a small landlocked Eastern European country (approximately 33,846 km²) positioned between Romania and Ukraine, lying between the Prut and Dniester rivers. The landscape is characterized by gently rolling hill country dominated by the central Codru forested uplands rising to Bălănești at 430 m (the nation's highest point), with the chernozem-rich lowland steppe of Bugeac in the south, the wine-growing valleys of the Bessarabian centre, and the breakaway Transnistria region along the Dniester left bank.

The climate is moderately continental — humid continental (Dfa / Dfb on the borderline) across the country with hot dry summers and cold often-snowy winters, modulated by occasional Black Sea moisture inputs but largely shaped by Eurasian continental airmasses.

Chișinău averages −3°C in January and 22°C in July with 540 mm of rainfall peaking in summer. Bălți in the north records −5°C in January and 21°C in July with 540 mm. Cahul in the south averages −2°C in January and 23°C in July with 510 mm. Tiraspol in Transnistria records −3°C in January and 22°C in July with 500 mm. The Codru forested uplands average −4°C in January and 20°C in July with 600 mm.

Snow cover typically persists 60–90 days per year. The all-time temperature range extends from approximately −33.5°C at Brătușeni in January 1942 to 41.5°C at Camenca in July 2007. Major weather events include the severe August 2006 hailstorm that damaged Codru vineyards, the severe July 2008 Prut River floods (Moldova's worst in decades), the August 2012 record 41.5°C heatwave, recurrent severe multi-year droughts including the 2007 and 2020 events that crippled the wine harvest, the severe February 2012 cold snap (−30°C in central Moldova), and accelerating Bessarabian steppe desertification stressing rainfed agriculture.

Our archive covers 4 Moldovan cities with daily ERA5 reanalysis data going back to 1940.
