Weather in December
Temperature
December, characterized by an average high temperature of 29.8°C (85.6°F) and a low temperature of 22.7°C (72.9°F), is generally the coldest month.Heat index
For most parts of December, the heat index is evaluated at a fiery hot 35°C (95°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
