Heat index

In September, the average heat index is estimated at a sweltering 36°C (96.8°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Research indicates the heat index considers values in shaded locales and with light winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Humidity

In September, the average relative humidity is 85%.

UV index

April through September, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the ordinary person.
Note: The daily high UV index of 6 during September translates into the following recommendations:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
