The climate in EstoniaAverage daytime and nighttime temperatures
All climatic diagrams of this page are taken from the collected data from 2 measuring stations in Estonia.
All data correspond to the average monthly values of the last 20 years.

Climate zone: Moderate zone of the northern hemisphere
The climate in Estonia widely corresponds to the German weather conditions. It is cold, wet and a few beautiful summer months are also happening. It won't be really warm here and given to the water temperatures of 16 degrees maximum you will leave your bathing togs at home. Due to the warmer temperatures the best time for traveling is from May to September. Nearly unattractive for tourists are the cold months from November to March.

Temperature records of the last 63 yearsThe hottest temperature measured from 1957 to October 2020 was reported by the Tallinn Harku weather station. In July 2018 the record temperature of 34.2 °C was reported here. The hottest summer from July to September, based on all 3 weather stations in Estonia below 70 metres altitude, was recorded in 2018 with an average temperature of 17.7 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 15.3 degrees Celsius. The average maximum daily temperature at that time was 21.4 °C.
The coldest day in these 63 years was reported by the weather station Tallinn Harku. Here the temperature dropped to -27.3 °C in February 2012. Tallinn Harku lies at an altitude of 34 meters above sea level. The coldest winter (January to March) was in 1963 with an average temperature of -8.6 °C. In Estonia, it is usual to have about 6.2 degrees more at -2.4 °C for this three-month period.
Long-term development of temperatures from 1991 - 2019In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 2 measuring points in order to have actually comparable data over as long a period as possible.
In the years 1991 to 2019 there were only these 2 weather stations in the whole country, which reported continuous temperature values (Tallinn Harku, Tartu Toravere). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 2010 with 22.1 °C. 2010 was the coldest month with an average temperature of -12.4 °C.
The average annual temperature was about 5.9 °C in the years after 1991 and about 7.0 °C in the last years before 2019. So in less than 29 years it has increased by about 1.1 °C. This trend only applies to the selected 2 weather stations in Estonia. A considerably more comprehensive evaluation of the global warming has been provided separately.
