Climate in Finland

Finland is located in Europe. The country is washed by three seas, such as the Baltic Sea, the Gulf of Finland, the Gulf of Bothnia. Finland - has a fairly long coastline. To determine the temperature of the water in it, we track 41 settlements and resorts.
The climate in Finland is temperate continental, in the north it experiences a powerful “warming» influence of the North Atlantic current, in the southwest it is transitional from temperate maritime to continental. Mild snowy winters and fairly warm summers are characteristic. The highest temperature in summer is from + 25°C to + 30°C, and the average is about + 18°C, while the water temperature in shallow lakes and on the coast quickly reaches + 20°C and higher. In winter, the temperature often drops below -20°C, but average temperatures in this case range from -3°C in the south (with frequent thaws) to -14°C in the north of the country. Beyond the Arctic Circle, in the summer the sun does not fall over the horizon for 73 days, and in winter there comes a polar night (“kaamos»), lasting up to 50 days. Precipitation is 400-700 mm per year, snow in the south of the country lies 3-5 months, in the north - about 7 months. However,In recent years, stable snow cover in the south of the country, especially in the capital, has not always formed, thaws have become more frequent in central regions. At the same time, less precipitation falls on the west coast than in the inland lake regions. The wettest month is August, the driest period is April-May.
