Weather in September
Temperature
The start of September signals a gentle decrease in the average high-temperature, transitioning from a hot 87.4°F (30.8°C) in August to a moderately hot 80.8°F (27.1°C). Victoria cools down to an average low-temperature of 61.7°F (16.5°C) throughout the month of September.Heat index
In September, the average heat index is calculated to be 84.2°F (29°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
