Climate: Montana In The United States

Climate in Montana(United States)Average daytime and nighttime temperaturesAll climate diagrams on this site result from the collected data from six measuring weather stations in Montana.Weather stations at an altitude above 1190m have not been included.All data correspond to the average monthly values of the last 20 years. Country data: United StatesClimate for all United States Montana is one of the cooler regions in the United States of America, with an average daily high temperature of 15 degrees. The climate is varied and offers seasons with strong winters and warm summers. › Daylengths and sun positions in the United States of America› Compare climate with other regions or countriesSunshine hours per dayThe 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 12 hours per day, July is the sunniest month in federated state Montana. In December, the sun shines the least.Rain days per monthA rain day is a day on which at least 1 mm of precipitation (=1 liter) per square meter falls. This can be rain, snow, hail, or even dew. So it doesn't have to rain all day. With 9 rain days, May offers the most rain days, while July has the fewest.The threshold of 0.1 mm, or 1 liter, was set by the World Meteorological Organization (WMO). In the US, the limit is 0.1 inches, or 2.54 mm. In other countries, 0.1 mm (~0.004 inches) is sometimes used. We use the internationally accepted version of the WMO here.Precipitation amount in mm/dayThe 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 0.6 mm, the least amount of rain falls in January. June, on the other hand, has the most rain.Relative humidity in %Warm air can absorb more moisture than cold air. The relative humidity indicates how much moisture can be physically contained in the air. At high humidity, a person feels uncomfortable and perceives this as oppressive. In general, a relative humidity of 40-60% feels pleasant. With only 46% humidity on average, it is quite dry in July. The highest value of 68% is experienced here in December.Absolute humidity in g/m³In 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.HumidexThe "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.Climate charts for other federated states in the United StatesPennsylvaniaColoradoFloridaMichiganOklahomaOregonIndianaWashington, D.C.IllinoisKansasNew MexicoArizonaOhioAlabamaArkansasAlaskaGeorgiaHawaiiConnecticutDelawareCaliforniaKentuckyIowaIdahoLouisianaMaineMassachusettsMarylandMissouriNebraskaMississippiMinnesotaNevadaNew JerseyMontanaNew YorkNorth CarolinaNew HampshireNorth DakotaSouth DakotaSouth CarolinaRhode IslandUtahTennesseeTexasWashingtonVermontVirginiaWest VirginiaWyomingWisconsin
