Weather in September
Temperature
The advent of September reveals an average high-temperature of a still tropical 34.4°C (93.9°F), showing minimal difference from the prior month. The average nighttime temperature lowers to a warm 25.5°C (77.9°F) throughout September.Heat index
September's mean heat index is estimated at a life-threatening hot 48°C (118.4°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Sunshine
In September, the average sunshine is 8.7h.UV index
April through June, September and October, with an average maximum UV index of 8, are months with the highest UV index. A UV Index of 8 to 10 symbolizes a very high health hazard from unsafe exposure to UV radiation for the average person.Note: The daily high UV index of 8 during September translates into the following recommendations:
Taking safety measures is non-negotiable; skin and eyes can be swiftly affected if neglected. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
