Weather in September

September, the first month of the autumn in Prague, is still a warm month, with an average temperature fluctuating between 85.8°F (29.9°C) and 65.1°F (18.4°C).

Temperature

Prague's progression into September involves a gentle drop in the average high-temperature, from a tropical 91.9°F (33.3°C) in August to a warm 85.8°F (29.9°C). In September, the recorded average low-temperature is a comfortable 65.1°F (18.4°C).

Heat index

September's heat index is evaluated at a torrid 95°F (35°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

In September, the average relative humidity is 72%.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Boost your sun resistance with garments that are densely woven yet spacious.
