Weather in December
The last month of the year, December, continues the trend set in November, characterized by high temperatures and regular rainfall. The temperature peaks at 33°C (91.4°F), marking one of the highest for the year, and the precipitation volume is significant at 104mm (4.09"). As December’s weather conditions manifest, it becomes evident that a full circle completes and previous weather conditions are on the horizon, tying the end of the year back to its start.Temperature
The introduction of December notes a subtle temperature variation to a still hot 33°C (91.4°F) from November's 31.4°C (88.5°F). During December, the temperature is averaged to a low of 22.3°C (72.1°F) at night.Heat index
December's average heat index is appraised at a blisteringly hot 43°C (109.4°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
