Heat index

For most parts of September, the heat index is evaluated at a fiery hot 39°C (102.2°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

July through September, with an average relative humidity of 81%, are the most humid months.

Note: In September, the maximum UV index of 7 suggests these recommendations:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
