May brings substantial changes to the weather pattern in
Koulouba. This transition involves significant rainfall, which now totals 71mm (2.8"), adding a burst of green to the previously dry landscapes. With the arriving rains, the town experiences a significant enrichment of its flora as the brown, arid scenes of the past months gradually turn green. A rapid increase in atmospheric moisture is concurrently observed, triggering a rise in relative humidity. The approach of the wet season is indicated by these climatic alterations.
Temperature
The start of May sees the average high-temperature at a still very hot 37.3°C (99.1°F), showing little difference from
April's 39.1°C (102.4°F). An average nighttime temperature of 25.5°C (77.9°F) is recorded during May.
Heat index
May's heat index is estimated at a blazing hot 48°C (118.4°F).
Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical 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 hold particular importance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
