Weather in December
Temperature
The beginning of December reveals an average high-temperature of a still tropical 30.5°C (86.9°F), showing minimal deviation from the previous month. Winongo, in December, experiences an average temperature of 23.6°C (74.5°F) at night.Heat index
The heat index for December is estimated at a blistering 40°C (104°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
