Weather in May
Temperature
The onset of May brings a minor temperature shift, with the average high-temperature moving from a warm 79°F (26.1°C) in April to a still moderately hot 85.3°F (29.6°C). Louise observes an average nighttime temperature of 69.3°F (20.7°C) during May.Heat index
May's average heat index is calculated to be a sweltering 96.8°F (36°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

In May, the average daily maximum UV index is 6. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for average individuals.Note: An average maximum UV index of 6 in May leads to these recommendations:
Exercise precautions and adapt sun safety practices. Defence against skin and eye affliction is paramount. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
