Hamburg has maritime weather with moderately warm and sometimes humid summers. The weather in September usually is fine with daytime high temperatures in the 20s (°C). In the night the temperatures sometimes fall below 10°C, so better take a light pullover or a jacket with you. And, being in Hamburg, it is never a bad idea to take an umbrella as rain showers are frequent even in September.
