June signifies the onset of the wet season in
Koulouba. Rainfall reaches a substantial amount of 110mm (4.33"), marking a notable escalation in the town's weather conditions. The humidity levels continue with their upward trend, creating a stronger presence of moisture in the atmosphere. The bulk of the rainfall initiates further growth and proliferation of the town's vegetation. Prolonged sunshine hours are a characteristic of June, illuminating the verdurous landscapes despite the rains.
Temperature
Koulouba's progression into June involves a minor drop in the average high-temperature, slightly receding from a torrid 37.3°C (99.1°F) in
May to a tropical 34.3°C (93.7°F). The average low-temperature during June nights is a warm 23.9°C (75°F).
Heat index
June's mean heat index is appraised at a blistering 43°C (109.4°F).
Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
