Heat index

For May, the heat index is evaluated at a torrid 39°C (102.2°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

With an average relative humidity of 46%, May is the least humid month.

Always stay safe. Unprotected skin and eyes can get damaged rapidly. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Even on overcast days, ensure the application and frequent reapplication of sunscreen with at least an SPF 30, especially post swim or outdoor exercise.
