Weather in September
Temperature
Astakos, Greece, in September demonstrates a small temperature transition, adjusting from an average high of a tropical 32.7°C (90.9°F) in August to a warm 27.1°C (80.8°F). Nighttime temperature experiences an average drop to an enjoyable 18°C (64.4°F) in September.Heat index
During September, the heat index is calculated to be 28°C (82.4°F). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. 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. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
