Heat index

The heat index in September is computed to be a torrid 96.8°F (36°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.
Understand that the heat index values take into account shaded locations and mild winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Note: The daily high UV index of 7 during September translates into the following recommendations:
Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Alert! UV radiation becomes sharper due to reflections from sand and water.
