May, the last month of the spring in Mambonco, is another extremely hot month, with an average temperature varying between 41.3°C (106.3°F) and 23.8°C (74.8°F).

Temperature

May's weather displays an average high-temperature of a still blistering 41.3°C (106.3°F), slightly varied from April's 42.1°C (107.8°F). Despite a significant disparity with daytime temperatures, an average low-temperature of 23.8°C (74.8°F) is recorded during May.

Heat index

May's heat index is calculated to be a life-threatening hot 54°C (129.2°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Understanding the heat index involves considering values for shaded locales with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', quantifies the warmth felt when relative humidity is considered. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Note: The daily high UV index of 8 in May translates into this advice:
Never neglect to protect yourself. Eyes and skin can suffer swift damage. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
