Heat index

September's mean heat index is calculated to be a torrid 38°C (100.4°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Humidity

In September, the average relative humidity is 83%.

UV index

The months with the highest UV index are March through June and September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for the ordinary person.
Note: In September, the maximum UV index of 7 translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
