Sinda, Congo

Temperature

November and December are characterised by lowest temperatures, with an average high of 29.5°C (85.1°F).

Heat index

December's heat index is calculated to be a torrid 38°C (100.4°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Deflect overexposure. Sun protection is a necessity. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
