Temperature

May's onset witnesses a minor shift in the average high-temperature, moving from a moderately hot 77.9°F (25.5°C) in April to a still warm 85.3°F (29.6°C). A sharp reduction from the daytime highs is witnessed during May, with nighttime temperatures averaging a low of 63.1°F (17.3°C).

Heat index

May's mean heat index is evaluated at a very hot 95°F (35°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. 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 extremely significant for babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
