May weather forecast
Ourou, Mali

The last month of the spring, May, is also a sweltering month in Ourou, Mali, with temperature in the range of an average high of 39.4°C (102.9°F) and an average low of 26.8°C (80.2°F).

Temperature

The start of May marks an average high-temperature of a fiery hot 39.4°C (102.9°F), hardly distinguishable from the conditions in April. Contrary to the day's heat, an average low-temperature of 26.8°C (80.2°F) is recorded during the nights in May.

Heat index

The average heat index in May is estimated at a burning hot 48°C (118.4°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
