Weather in December
Temperature
December's advent presents an average high-temperature of a still warm 29.5°C (85.1°F), indicating a slight variation from the conditions of the previous month. In the month of December, the nighttime temperature dips to a steady average of 17.6°C (63.7°F).Heat index
December's average heat index is calculated to be a hot 32°C (89.6°F). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.Realize that the values for the heat index are set for shaded places and light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.

Enhance your sun protection with tightly woven, yet airy clothing.
