Heat index

The heat index value during May is evaluated at a fiery hot 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
