Weather in September
Temperature
September's arrival brings an average high-temperature of a still hot 30.1°C (86.2°F), demonstrating subtle variation from the preceding month. Nighttime temperatures consistently average a pleasant 21.4°C (70.5°F) during September.Heat index
The heat index value for September is estimated at a very hot 37°C (98.6°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
