Weather in September
Temperature
The warmest temperatures occur during September, when averages reach a peak of 31.5°C (88.7°F) and a low of 16.2°C (61.2°F).Heat index
The heat index for September is estimated at a very hot 35°C (95°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
