Weather in December
Temperature
The ushering in of December brings an average high-temperature of a moderately hot 29.4°C (84.9°F), closely mirroring the 30.5°C (86.9°F) of November. December nights experience a minor temperature downturn to 24.5°C (76.1°F).Heat index
December's mean heat index is computed to be a very hot 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Heat index details are generally centered around shaded locations and a mild breeze. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives a temperature feeling by integrating air temperature and humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
