May's average heat index is estimated at a scorching 42°C (107.6°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Limit direct exposure to the Sun during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
