Weather in September
Temperature
An average high-temperature of a still hot 87.3°F (30.7°C) marks September, exhibiting a close resemblance to the conditions in August. An average low-temperature of 70.5°F (21.4°C) is observed during the September nights.Heat index
In September, the average heat index is calculated to be a scorching 104°F (40°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings 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 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. 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 remain especially vital for babies and toddlers. 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
