Weather in September
Temperature
The arrival of September corresponds with a light shift in temperature, down from a tropical 86.5°F (30.3°C) in August to a moderately hot 81.1°F (27.3°C). An average nighttime temperature of 61.9°F (16.6°C) is observed in Fosterville during September.Heat index
September's mean heat index is computed to be a tropical 86°F (30°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
