Weather in September
Temperature
The arrival of September brings an average high-temperature of a still hot 31.2°C (88.2°F), subtly diverging from August's 30.2°C (86.4°F). The mean low-temperature during September nights is a pleasant 22.5°C (72.5°F).Heat index
September's mean heat index is evaluated at a scorching 41°C (105.8°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
