Weather in May
Temperature
The arrival of May witnesses a small shift in the average high-temperature, moving from a warm 78.4°F (25.8°C) in April to a still moderately hot 85.6°F (29.8°C). Throughout May, the temperature falls to an average low of 65.7°F (18.7°C).Heat index
During May, the heat index is estimated at a very hot 96.8°F (36°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
