Traveller notes on Heidelberg in January
Other months in Heidelberg
Germany's forum calls June genuinely variable — anywhere from hot and humid around 30-35°C to chilly and rainy at 15-20°C in the same month. Regulars' standard packing list covers both: summer clothes plus a hooded rain jacket and a warm sweater, since Heidelberg's Neckar valley runs a touch milder than much of the rest of the country but not immune to the swings.
