Weather in September
Temperature
September reveals a small adjustment in temperature, transitioning from an average high of a hot 86.9°F (30.5°C) in August to a moderately hot 81°F (27.2°C). During September, Hillsview witnesses a consistent average low-temperature of 59.9°F (15.5°C).Heat index
September's mean heat index is evaluated at a tropical 86°F (30°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
