For May, the heat index is appraised at a very hot 95°F (35°C). Implement more preventive measures, heat cramps and heat exhaustion are probable.

Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
