Daily maximum temperatures
The highest daytime temperatures in Estonia are reached in July with an average of 22.9 °C. The coldest month, on the other hand, is January, with an average of just -2.1 °C. In Spain, August is the warmest month, with 29.8 °C. There, it is coolest in January with an average of 13.4 °C.
Night time lows
At night, it cools down to varying degrees depending on the country and altitude. In Estonia, temperatures drop as low as -6.9 °C in February. The warmest nights are in July at 13.3 °C. In Spain, it is coolest at night in January at 5.0 °C and warmest in August at 18.4 °C. This corresponds to a cooling of 3.8 to 10.8 °C in Estonia and 8.3 to 11.5 °C in Spain.
The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.
Rain days per month
By definition, a rain day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high — insofar as the water does not seep away or evaporate. So it does not have to rain all day long. December brings the most rainy days (13.8) in Estonia. With an average of only 7.4 days, April is the friendliest. In Spain, it rains most often in November with 8.1 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings a varying amount of water with it. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in Estonia occurs in August, when about 2.9 liters per square meter fall per day. In Spain, the average amount of precipitation ranges from 0.6 liters per day in July to 2.9 in November. However, these are average values. If you consider that there are only 12.0 rainy days in Estonia in August, each of them accounts for about 7.2 liters.
Sunshine hours per day
With 2,555 hours of sunshine per year, Spain is in the lead. The most hours of sunshine (10.2 per day) are in July. Estonia falls into second place with only 1,825 hours. There the sun is visible in December for only 0.8 hours per day, so not hidden behind clouds.
Hours of daylight
The length of a day varies throughout the year and depends on the distance from the equator. In December, the day in Estonia is only 6.5 hours long. In June, on the other hand, it is 18.3 hours. In Spain, it is 9.8 hours in December and 14.6 in June.
