Weather in December

The arrival of December in Ruacana, Namibia, denotes a barely perceptible change in the average high-temperatures to a still tropical 32°C (89.6°F) from November's 33.1°C (91.6°F). The average low-temperature, in December, is a moderately hot 23.2°C (73.8°F).Heat index
Throughout December, the heat index is computed to be a hot 33°C (91.4°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
