Weather in September
Temperature
As September arrives, Dalyan's weather displays a minor decrease in high-temperatures, transitioning from August's tropical 32.4°C (90.3°F) to a warm 28.5°C (83.3°F). During September, the temperature tends to dip to an average of 20.1°C (68.2°F) at night.Heat index
September's heat index is computed to be 29°C (84.2°F). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. 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. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.

Shield from overexposure. Defense against sun-related harm is required. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
