Weather in September
Temperature
As August transitions into September, the average high-temperature rests at a still tropical 30.6°C (87.1°F), maintaining a close resemblance to the previous month. In Sigli, the expected average low-temperature for September is a moderately hot 24.5°C (76.1°F).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.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an estimation of the warmth sensation when considering humidity levels. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Rising body temperatures due to excess heat retention could signify impending heat disorders.

A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.Note: A maximum high UV index of 7 in September translates into the following recommendations:
Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. 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. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Stay alert! Snow's reflective properties can almost double the UV radiation from the Sun.
