Weather in September
Temperature
The arrival of September corresponds with a minor reduction in the average high-temperature, down from August's hot 86.4°F (30.2°C) to a warm 81°F (27.2°C). Lebanon, during the month of September, experiences an average low-temperature of 61.5°F (16.4°C).Heat index
For most parts of September, the heat index is computed to be a hot 86°F (30°C). If one continues to be active during enduring exposure, it could result in fatigue and heat cramps.Always consider that heat index estimations are for light winds and places in the shade. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
