Weather in September
Temperature
A minimal variation is noted in Weatherly Park's average high-temperature at the onset of September, reaching a moderately hot 85.3°F (29.6°C) from August's 89.8°F (32.1°C). In the month of September, the average temperature dips to a pleasant 69.1°F (20.6°C) during the night.Heat index
For September, the heat index is appraised at a fiery hot 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. 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 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
