Weather in September
Temperature
With the onset of September, a high-temperature average of a still moderately hot 27.1°C (80.8°F) emerges, matching that of August. Throughout the nights in September, an average low-temperature of 18.7°C (65.7°F) is noted in Monaragala.Heat index
September's heat index is computed to be a hot 30°C (86°F). 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. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
