Daily maximum temperatures

The highest daytime temperatures in Tamil Nadu are reached in April with an average of 34.3 °C. The coldest month, on the other hand, is December, with an average of just 29.7 °C. In Seoul, August is the warmest month, with 29.8 °C. There, it is coolest in January with an average of 1.9 °C.

Night time lows

At night, it cools down to varying degrees depending on the country and altitude. In Tamil Nadu, temperatures drop as low as 21.1 °C in January. The warmest nights are in May with 25.9 °C. In Seoul, it is coolest at night in January with -5.4 °C and warmest in August with 23.3 °C. This corresponds to a cooling of 7.1 to 10.1 °C in Tamil Nadu and 6.2 to 9.3 °C in Seoul.

Humidity

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.

Humidex

Humidex is an approximate, sensed temperature calculated on the basis of air temperature, dew point and humidity. It was developed in 1965 by the Canadian meteorologists J. M. Masterton and F. A. Richardson. Since the wind speed is ignored here, it is not very meaningful in areas below approx. 15°C. Above that, it is more reliable, since at higher temperatures humidity plays a greater role than wind.

Rainy days per month

By definition, a rainy 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. November brings the most rainy days (13.0) in Tamil Nadu. With an average of only 1.6 days, February is the friendliest. In Seoul, it rains most often in July with 12.6 days.

Precipitation amount per day

Depending on the season and the location of a country, the wind brings with it a varying amount of water. 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 Tamil Nadu occurs in November. Then about 8.8 liters per square meter fall per day. In Seoul, the average amount of precipitation ranges from 0.5 liters per day in January to 12.7 in July. However, these are average values. If you consider that there are only 13.0 rainy days in Tamil Nadu in November, each of them accounts for about 20.2 liters.

Sunshine hours per day

With 2300 hours of sunshine per year, Seoul is in the lead. The most hours of sunshine (7.6 per day) are in May. Tamil Nadu falls into second place with only 2154 hours. There the sun is visible in July even only 4.0 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. The length of day measured here is the period between the middle of the morning and evening twilight. In January, the day in Tamil Nadu is only 11.9 hours long. In June, on the other hand, it is 13.1 hours. In Seoul, it is 10.1 hours in December and 15.2 in June.
