Temperature
Dushanbe experiences a moderate temperature shift at the start of September, with average high-temperatures adjusting a bit from a tropical 34.3°C (93.7°F) in
August to a still hot 30.7°C (87.3°F). Dushanbe sees a major change from daytime highs, with the nighttime temperature dipping to a fresh 11.1°C (52°F) on average during September.
Heat index
For most parts of September, the heat index is estimated at a tropical 31°C (87.8°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight might lead to a heat index increase by up to 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. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
