Weather in September
Temperature
Peak temperatures are observed in August and September, averaging a high-temperature of 32.8°C (91°F).Heat index
September's mean heat index is computed to be a burning hot 47°C (116.6°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.One should consider that heat index numbers are for shaded settings and light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
