Weather in September
Temperature
The onset of September notes an average high-temperature of a warm 82.8°F (28.2°C), subtly shifted from August's 86.9°F (30.5°C). Throughout September, an average low-temperature of 71.1°F (21.7°C) is expected in Quarantine.Heat index
For September, the heat index is computed to be a tropical 89.6°F (32°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
