Heat index

The heat index value for September is estimated at a sweltering 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The months with the highest humidity are July through September, with an average relative humidity of 85%.

Note: The maximum UV index, 7 during September, leads to the following recommendations:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Stay cautious! Sand and water reflections increase UV radiation potency.
