Temperature

As August transitions into September, the average high-temperature rests at a tropical 30.8°C (87.4°F), maintaining a close resemblance to the previous month. Throughout the month of September, Gagasari expects an average low of 22.8°C (73°F).

Heat index

September's heat index is appraised at a torrid 37°C (98.6°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Data suggests that the heat index is set for environments in shade and with a light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unprotected exposure to Sun's UV rays for the average person.
Note: A daily maximum UV index of 7 in September translates into the following instructions:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
