Vejret i Nuremberg (Nurnberg) i december

Regulars describe a real range of outcomes here rather than one settled early-autumn pattern - one visitor's late-September trip turned genuinely cold and grim, closer to a November feel with morning rain and heavy cloud cover, while other years and other visitors get a mild, mostly pleasant stretch instead. Our row backs a moderate average across that range, 21.3C over 9.5C nights feeling 8C, with 56.4mm of rain across 8.4 days. The practical read is to pack for both outcomes rather than commit to one - layers plus a proper rain jacket - since which version of the month a visitor gets is genuinely down to the year rather than the date within it. The record: humidity 74 percent, 8.8 hours of sun, a 13 kph wind and AQI 42.

Regulars give mid-August as anywhere from 20 to 35C and refuse to narrow it - sun or rain, with a good chance of humidity and thunderstorms, and central European forecasts good for about three days. So they tell you to pack for both ends: a warm sweater and long trousers as well as a raincoat. Our row sits in the middle at 26.2C over 13.3C. Two practical notes follow. Air conditioning is not a given, so check the hotel has it if it matters; and the rock passages under the old town hold about 13C on the hottest day, which is the city's own answer to its worst afternoons. The record: 73.7mm across 8.5 days, 10.7 hours of sun and AQI 46.

June in Franconia is warm and can turn humid, and regulars answer that with geography rather than a forecast: the Bergkirchweih at Erlangen, a short ride from Nuremberg and running from late May into mid-June, is a huge beer garden set in woodland on a hillside above the old brewery cellars, so the shade under the trees is the point and not a bonus. There is no ticket and no entry fee - you pay for what you eat and drink. Our row gives 25.5C over a cool 12.5C night at 68 percent humidity, with 66.7mm across 8.2 precipitation days, so an evening outdoors is a fair bet rather than a certainty and a layer is worth having once the sun goes. The record: 12 hours of sun, 16.2 hours of daylight and AQI 51.

Nuremberg forum threads describe winter here as typically hovering around 0C, plus or minus 5 degrees, with posters noting snow becomes more likely moving through January into February even as the coldest stretch tends to land earlier in December. Whether a given day brings snow, rain or slush was described as coming down largely to elevation, since temperatures near freezing can tip either way depending on how high up you are. The consistent packing advice was real layering - a waterproof shell jacket over fleece, a hat and hood, and warm, water-resistant footwear rather than running shoes, since posters were clear that wet feet in near-freezing temperatures make for a genuinely unpleasant day of walking.
