Weather in September
Temperature
September ushers in an average high-temperature of a moderately hot 85.5°F (29.7°C), aligning closely with the preceding month. During the nights in September, an average low-temperature of 66.4°F (19.1°C) is observed.Heat index
September's mean heat index is appraised at a very hot 95°F (35°C). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Keep in mind that shade structures may not provide complete protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
