Weather in September
Temperature
The transition into September marks the average high-temperature at a still warm 29.1°C (84.4°F), differing minimally from August's 29.4°C (84.9°F). In September, Alanje experiences an average nighttime temperature of 22.5°C (72.5°F).Heat index
The heat index in September is calculated to be a very hot 36°C (96.8°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
