In Germany, the precipitation is spread over the whole year, so even in May (which is often referred to as a very nice time of the year), you should be prepared for rain (bring a rain jacket or an umbrella).

In late May, the temperature usually drops to about 5-10°C (40-50°F) during the nights and rises to about 15-20°C (60-70°F) on cloudy/rainy days and about ~25°C (~80°F) on sunny days.

The sun rises early (around 5 a.m.) and sets late (around 9.30 p.m.).

Recent forecast

The weather so far has been cool, overcast with a few raindrops. Unfortunately, the forecast for the next two days is very similar (it will probably become somewhat warmer).
