Weather in December
Temperature
December witnesses a subtle temperature ascent, adjusting from a moderately hot 26.4°C (79.5°F) in November to a still warm 29.4°C (84.9°F). Roleystone documents a substantial deviation from daytime highs with a consistent low-temperature of 16.9°C (62.4°F) during December nights.Heat index
December's mean heat index is calculated to be a hot 30°C (86°F). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
