Weather in September
Temperature
Batu records an average high-temperature of a still hot 32.2°C (90°F) as September arrives, nearly mirroring the previous month's climate. During the nights in September, Batu observes an average low-temperature of 23.2°C (73.8°F).Heat index
For most parts of September, the heat index is calculated to be a blistering 43°C (109.4°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
