Weather in September
Temperature
During September, Otra Banda observes a subtle ascent to a still hot 30.5°C (86.9°F) from August's 30.7°C (87.3°F) in the average high-temperature. Otra Banda experiences a mean temperature of 24.8°C (76.6°F) during September nights.Heat index
For most parts of September, the heat index is computed to be a sweltering 39°C (102.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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 natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for the average person.Note: A daily maximum UV index of 7 in September translates into the following instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. 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. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
