December weather forecast
Negomano, Mozambique

The first month of the summer, December, is still a tropical month in Negomano, Mozambique, with temperature in the range of an average high of 31.5°C (88.7°F) and an average low of 21.4°C (70.5°F).

Temperature

The beginning of December records an average high-temperature of a still hot 31.5°C (88.7°F), marking a negligible difference from November's 33.2°C (91.8°F). During December, Negomano witnesses a consistent average low-temperature of 21.4°C (70.5°F).

Heat index

December's heat index is calculated to be a blisteringly hot 42°C (107.6°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The average relative humidity in December is 78%.

Note: In December, the maximum UV index of 7 transforms into these recommendations:
Shield from overexposure. Defense against sun-related harm is required. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
