Weather in September
Temperature
The commencement of September records an average high-temperature of a still warm 27.3°C (81.1°F), barely varying from August's 26°C (78.8°F). An average low-temperature of 16.5°C (61.7°F) is noted in Handei during the month of September.Heat index
In September, the average heat index is computed to be a hot 30°C (86°F). If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.Note that heat index values are valued for light wind and location in the shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
