Weather in September

Lunugala sees an almost indistinguishable change in average high-temperatures from August to a still warm 80.8°F in September. The nighttime temperature, during September, averages of 65.7°F.Heat index
September's mean heat index is calculated to be a hot 86°F. Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
