Weather in September
September, the first month of the autumn in Hamburg, is still a tropical month, with an average temperature varying between 67.1°F (19.5°C) and 86.4°F (30.2°C).Temperature
The commencement of September includes a gentle temperature shift, with the average high-temperature dropping a bit from a tropical 91.9°F (33.3°C) in August to a still hot 86.4°F (30.2°C). During the month of September, an average temperature of 67.1°F (19.5°C) is noted during the nights in Hamburg.Heat index
September's average heat index is appraised at a very hot 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.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 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Limit exposure to direct sunlight during these hours. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
