Heat index

The heat index value for May is calculated to be a burning hot 49°C (120.2°F). Take note: Heat exhaustion and heat cramps are expected. Heatstroke can occur with prolonged effort.
Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
