Hamburg weather by month
Averages for 1991–2020 at the Hamburg-Fuhlsbuettel weather station (10.7 m above sea level), from the WMO climate normals, next to each month's share of Germany's tourist nights (Eurostat, 2025) in 2025. The shares are for the whole of Germany, not Hamburg alone. These are long-term averages, not a forecast. A rainy day is one with at least 1 mm of rain.

Golden hour
Evening golden hour is our calculation for the 15th of each month of 2026: the time the sun takes to go from 6° above to 4° below the horizon (there is no official definition).
The quietest and busiest months
In 2025, January was Germany's quietest month (4.8% of the year's tourist nights): at Hamburg's station that month averages a high of 4.2 °C, a low of −0.5 °C and 67 mm of rain. August was the busiest (12.4%): average high 23.0 °C, average low 13.1 °C, 78 mm of rain. The visitor figures are for the whole country, and they do not show that the weather makes a month busier or quieter, so we do not say it does.
What these figures are
One weather station stands for Hamburg; places nearby can differ, especially by height or distance from the sea. For the rest of Germany, including regions and holidays, see our Germany page; for other places, the weather by city list and golden hour by place.
