Weather in December
Temperature
The unfolding of December shows an average high-temperature of a still moderately hot 29.6°C (85.3°F), indicating a slight variance from November's 29.5°C (85.1°F). Salcoatitan's nights in December experience an average temperature drop to a pleasant 20.7°C (69.3°F).Heat index
December's heat index is estimated at a hot 34°C (93.2°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
