Weather in May
Temperature
The warmest period is usually observed in May, July through September, with the average high-temperature peaking at 32.3°C (90.1°F).Heat index
During May, the heat index is estimated at a burning hot 47°C (116.6°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
