Weather in September
Temperature
Leona's weather subtly changes with the onset of September, barely falling from a very hot 96.3°F (35.7°C) in August to a hot 89.1°F (31.7°C). During the September nights, an average temperature of 69.3°F (20.7°C) is observed.Heat index
September's mean heat index is evaluated at a blisteringly hot 104°F (40°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 especially crucial for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
