Weather in September

September, the first month of the spring in Tenjomaya, is a tropical month, with an average temperature fluctuating between 30.6°C (87.1°F) and 22.6°C (72.7°F).

Temperature

The commencement of September introduces an average high-temperature of a hot 30.6°C (87.1°F), closely mirroring the preceding month. Tenjomaya's September nights cool down to an average low-temperature of 22.6°C (72.7°F).

Heat index

The heat index in September is calculated to be a sweltering 37°C (98.6°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
