Weather in September
Temperature
With the advent of September, Kotagala's high-temperatures adjust to a still moderately hot 27.1°C (80.8°F), closely aligning with the preceding month. September witnesses an average nighttime temperature of 18.7°C (65.7°F).Heat index
Throughout September, the heat index is computed to be a tropical 30°C (86°F). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Always consider that heat index estimations are for light winds and places in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. 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.
