Map from Google - Moldova

Moldova has a continental climate, with cold, snowy winters and warm summers. Since the prevailing currents come from the north or the west, the proximity of the Black Sea (which lies to the south-east) does not affect much the climate.
The Republic of Moldova is a Romanian-speaking country, and has been a Soviet republic until 1991.

Being a flat and small country, the climate is fairly homogeneous, with small differences; sometimes, however, it may happen that it can snow in the north and not in the south.

Precipitation in Moldova is not abundant, since it amounts to about 500 millimetres (20 inches) per year. The season in which precipitation is most frequent is winter, but given the low temperatures, it is not abundant, and occurs mostly in the form of light snow. The rainiest months in terms of quantity are June and July, mainly because of afternoon thunderstorms, but there are not more days with precipitation than in winter; in August, thunderstorms become less frequent.

Winter in Moldova is cold, with an average temperature in January around -3 °C (27 °F). Sometimes, mild and moist air masses from the Mediterranean may raise the temperature above freezing (0 °C or 32 °F) and melt the snow, while cold air masses of Arctic or Russian origin can lower the temperature by several degrees, down to around -20 °C (-4 °F) or even below. Cold records are around -35 °C (-31 °F) in the north (see Balti, Soroca), and -30 °C (-22 °F) in Chisinau.

Summer in Moldova is warm: in the two warmest months (July and August), the average minimum temperature is around 14/15 °C in the north and 15/16 °C (59/61 °F) in the centre-south (so nights are usually pretty cool), while the maximum temperature is around 25/26 °C (77/79 °F) in the north, and 27/28 °C (81/82 °F) in the south. In the afternoon, thunderstorms may develop, especially in June and July. The sunshine amount is good: there are about 9 hours of sunshine per day from May to August, which means that the sun often shines. As mentioned, the temperature is normally acceptable, but sometimes there can be heat waves, capable of raising the temperature to around 35 °C (95 °F) and above, usually for a few days. In the capital Chisinau, the highest recorded temperature is 39 °C (102 °F).
Sometimes in summer, floods can occur (as happened in July 2008 and 2010), mostly because of heavy rains which may occur in the Carpathian region and then swell the Dniester (or Nistru) River, which has its source in that mountain range, in Ukraine.

The two intermediate seasons, spring and autumn, are quite short but pleasant: in May and September, the minimum and maximum temperatures are respectively around 11 and 22 °C (52 and 72 °F). In spring, the first mild or warm days can be followed by sudden drops in temperature, with possible snowfalls, especially in March and early April. In autumn, the first cold days occur in November, and sometimes in late October.
