Hours of sunshine per daySunshine hours per day in Eastern India
The number of hours of sunshine refers to the time when the sun is actually visible. That is, without any obstruction of visibility by clouds, fog or mountains. With 7 hours per day, April is the sunniest month in greater region Eastern India. In July the sun shines the shortest.
Rainy days per monthRainy days per month in Eastern India
A rainy day is a day on which at least an amount of 0.1 mm precipitation (=0.1 liter) per square meter falls. This can be rain, snow, hail or even dew. So it does not have to rain the whole day. With 20 rainy days, July offers the most number of rainy days, and in December the least.
Precipitation in mm/dayPrecipitation in Eastern India
The amount of precipitation is measured in millimeters per square meter. Thus, at two mm/day, two liters of water fall on one square meter within 24 hours. With only 0.2 mm, the least rain falls in December. July, on the other hand, has the most rain.
Water temperatureWater temperatures in Eastern India
Water temperature depends not only on solar radiation within the same region, but also on ocean currents. For example, depending on the season, cold or warm water masses are moved from other areas. The warmest temperatures in Eastern India are in May, when the water is 29 °C.
Relative humidity in %Relative humidity in Eastern India
Warm air can absorb more moisture than cold air. The relative humidity indicates how much moisture of the physically possible is actually contained in the air. At high humidity, the person feels uncomfortable and perceives this as oppressive. In general, a relative humidity of 40-60% gives as pleasant. With humidity averaging 83%, August is the most uncomfortable. In April, on the other hand, it is easier to endure.
Absolute humidity in g/m³Absolute humidity in Eastern India
In warm months, there is also a higher absolute humidity almost everywhere. At a temperature of 25°C, air can absorb up to 23 grams of water per cubic meter. At 20°C, it is only 17.3 grams. A relative humidity of 40% at 25°C thus corresponds to an absolute humidity of 9.2 grams of water. From a proportion of approx. 13.5 grams, humans perceive the air as muggy. This limit is reached in 9 months in Eastern India, although these are average values, and a month is rarely completely or not at all considered humid.
Humidex in °CHumidex in Eastern India
The "Humidex" (humidity index) is an index of well-being in warmer areas, calculated from the air temperature, relative humidity and dew point. The index corresponds approximately to the temperature felt. At high temperatures, the body transports heat away by sweating. At high humidity the ambient air can only absorb a small amount of sweat and thus one feels uncomfortable. An index of 20-29 is considered comfortable. Up to 39, people perceive the air as slightly uncomfortable, and above 40, as very uncomfortable. Values above 45 are dangerous in the long run and often lead to heat stroke.
