Weather in December
Temperature
December commences with an average high-temperature of a warm 29.7°C (85.5°F), showing little deviation from November's 30.5°C (86.9°F). Throughout December, Semplak encounters an average temperature drop to a still moderately hot 23.5°C (74.3°F).Heat index
For December, the heat index is calculated to be a fiery hot 36°C (96.8°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.The heat index's values are generally associated with conditions in shade and light breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
