Weather in September
Temperature
Sihanamaro's shift from August to September is accompanied by an average high-temperature of a still moderately hot 27.1°C (80.8°F), a slight deviation from 25.5°C (77.9°F). September generally records an average low-temperature of 19.3°C (66.7°F).Heat index
For September, the heat index is calculated to be 29°C (84.2°F). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
