Weather in September
Temperature
The onset of September aligns with a soft reduction in the average high-temperature, gently falling from a hot 89.6°F (32°C) in August to a warm 84.2°F (29°C). Throughout September, Separ encounters an average temperature drop to an enjoyable 66.4°F (19.1°C).Heat index
September's mean heat index is appraised at 84.2°F (29°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
