December weather forecast
Matundo, Mozambique

Finally, December brings the year to a close with the highest recorded rainfall, making it the wettest month in Matundo. Despite the increased precipitation and high relative humidity at 66%, December continues to sport warm temperatures. The considerable cloud cover of 38% collates with the increased rains, painting an accurate picture of the city’s monsoon mood. There is a notable reduction in wind speed, showing the lowest speeds since April, which records at an average of 7.8km/h (4.8mph). Despite the heavy monsoon conditions, this month also has the longest daylight hours, reaching an average of 13.1 hours.

Temperature

Transitioning from November to December, Matundo observes an average high-temperature of a tropical 34.1°C (93.4°F), differing subtly from the previous month. In December, the temperature drops to an average of 23.2°C (73.8°F) at night.

Heat index

Throughout December, the heat index is evaluated at a life-threatening hot 45°C (113°F). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. 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 particularly relevant to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
