Weather in January

January, the same as December, in Kiroli, Guinea, is another hot winter month, with an average temperature varying between 23.3°C (73.9°F) and 30.9°C (87.6°F).

Temperature

January's advent presents an average high-temperature of a still hot 30.9°C (87.6°F), indicating a slight variation from the conditions of the previous month. Kiroli's nighttime temperature during January is consistently averaged at a warm 23.3°C (73.9°F).

Heat index

The heat index value during January is evaluated at a torrid 35°C (95°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
