Weather in December
Temperature
The arrival of December brings a soft temperature shift, with the average high-temperature nudging from a warm 24.5°C (76.1°F) in November to a still moderately hot 27.7°C (81.9°F). Watchem's temperature exhibits a stark contrast from daytime to nighttime, averaging lows of 14.5°C (58.1°F) in December.Heat index
December's average heat index is estimated at 28°C (82.4°F). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.For clarity, heat index numbers account for light winds and areas under shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
