Winter, from December to February, is cold, with average temperatures hovering around freezing. Actually, during winter, different situations may occur.
There may be relatively mild periods, in which Atlantic currents prevail, it can rain and the temperatures can exceed 10 °C (50 °F); in these cases, however, wind and humidity can increase the feeling of cold.
Then, there are situations in which an high pressure system dominates, and the weather is cold and gray, with night frosts and daytime temperatures around freezing, or even a little below. Later, when the westerlies start to blow again, flowing above the layer of cold air, they can bring snow, sleet, rain mixed with snow or rain that freezes.
At other times, cold air masses of Siberian origin may cause snowfall and frost, sometimes intense. In the past, once every few years it happened that the temperature remained below freezing for an entire month; in recent years it has become more rare, however, sometimes waves of frost still occur, which may last for weeks, and in which the temperature can drop to -20 °C (-4 °F).

Spring, from March to May, is a season characterized by an unstable weather, in which the first warm days alternate with the return of cold weather. March is often still a cold month, with frequent snowfalls. In April, cold periods are still possible, with late snowfalls, especially in the first half of the month, but also the first mild days, in which the temperature can reach 20 °C (68 °F), especially in the second half of the month. In early May, it can still get cold; with the passing of days the first warm days occur, when the temperature can reach 25 °C (77 °F), and the first afternoon thunderstorms can burst.

Summer, from June to August, is pleasantly warm: daytime temperatures hover around 22 °C (72 °F) in June and 24/25 °C (75/77 °F) in July and August. However, nights are cool, and sometimes even a little cold. Atlantic depressions can arrive even in this season, bringing some cool and rainy days, while in periods of good weather the temperatures can get close to 30 °C (86 °F). There is some variability from year to year: there may be summers characterized by long warm and sunny periods, and others in which cool and rainy weather is more frequent. However, some hot days, with highs around 28/30 °C (82/86 °F), occur almost every year; occasionally there may be even waves of intense heat, with highs about 36/37 °C (97/99 °F), but usually they only last a day or two.
On sunny days, thunderstorms can break out in the afternoon.

In autumn, from September to November, the flow of Atlantic fronts, which had never completely stopped, resumes with greater frequency, although sometimes a period of good and unseasonably warm weather can occur, a sort of Indian summer, called Altweibersommer, in September and sometimes in October. Usually, September is still an acceptable month; cold and gray weather usually arrives in the second half of October or more likely in November, when the first snowfalls are also possible.

The amount of sunshine in Leipzig is never great, however it is passable from May to August, when the days are also very long, and there are about 7 hours of sunshine per day. From November to February, the sun rarely shines and the days are short.
