Weather in December
Temperature
The arrival of December sees a recorded average high-temperature of a still tropical 30.9°C (87.6°F), showing little divergence from the previous month's conditions. An average low-temperature of 21.1°C (70°F) is noted during the nights in December in Kepioudou, French Guiana.Heat index
Throughout December, the heat index is evaluated at a blistering 43°C (109.4°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.Consider that heat index readings are for situations in the shade and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
