Kumai's average high-temperature marks a still hot 33°C (91.4°F) with the advent of May, closely mirroring that of the preceding month. Kumai's nighttime temperature during May is consistently averaged at a moderately hot 23.7°C (74.7°F).

Heat index

In May, the average heat index is evaluated at a life-threatening hot 50°C (122°F). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.

The average relative humidity in May is 83%.

Note: A daily high UV index of 7 in May leads to these guidelines:
Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
