Weather in September
Temperature
The transition into September subtly indicates a reduction in the average high-temperature, down to a moderately hot 83.8°F (28.8°C) from August's hot 89.6°F (32°C). An average nighttime temperature of 65.1°F (18.4°C) is noted in Lando during the month of September.Heat index
For September, the heat index is estimated at a tropical 91.4°F (33°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
