A water temperature of 10 °C (50 °F) can lead to death in as little as one hour, and water temperatures near freezing can cause death in as little as 15 minutes. [37] During the sinking of the Titanic, most people who entered the −2 °C (28 °F) water died in 15–30 minutes. [38]
The wet-bulb temperature is the lowest temperature that can be reached under current ambient conditions by the evaporation of water only. Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32 °C (90 °F), equivalent to a heat index of 55 °C (131 °F). A reading of 35 °C (95 °F) – equivalent ...
Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
The daily average in July is 81.8 °F (27.7 °C), with highs exceeding 90 °F (32.2 °C) on 86 days per year and 100 °F (37.8 °C) on 3.9. Summer afternoon heat indices, much more often than the actual air temperature, are frequently at or above 100 °F. [46] The diurnal temperature variation tends to be large in spring and autumn. Rainfall is ...
The warmest calendar year in Fairbanks was 2019, when the average annual temperature was 32.5 °F (0.3 °C), while the coldest was 1956 with an annual mean temperature of 21.3 °F (−5.9 °C). The warmest month has been July 1975 with a monthly mean of 68.4 °F (20.2 °C) and the coldest January 1906 which averaged −36.4 °F (−38.0 °C).
Above approximately 3,250 metres (10,660 ft), the climate transitions to an ice cap climate, where the mean temperature from 1976-2000 was always below 0 °C (32 °F). At these altitudes, no plants can grow and the ground is either rock or ice. [ 3 ]
BMI is an accurate reflection of body fat percentage in the majority of the adult population. However it is less accurate in people such as body builders and pregnant women. [13] A formula combining BMI, age, and gender can be used to estimate a person's body fat percentage to an accuracy of 4%. [14]
