Weather in December
Temperature
Ambagahahena experiences a transition to a still warm 29.9°C (85.8°F) in average high-temperatures with the arrival of December, not greatly differing from November's 29.8°C (85.6°F). Ambagahahena witnesses an average low-temperature of 23.8°C (74.8°F) throughout the month of December.Heat index
December's mean heat index is estimated at a torrid 37°C (98.6°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.For clarity, heat index numbers account for light winds and areas under shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
