In contrast, winters are cold, with average temperatures just above freezing in January and December, and nighttime frosts. Spring and autumn are transitional seasons with moderate temperatures, gradually rising toward summer and dropping toward winter.

Precipitation in Passau is distributed relatively evenly throughout the year, though the total amount is modest, averaging 2-4 mm per month. However, the number of days with precipitation varies from 11 to 16 per month, meaning there is a chance of rain year-round. Travelers should be prepared for potential showers regardless of the season.

The climate in Passau is characterized by notable seasonal temperature fluctuations. Throughout the year, the average monthly temperature ranges from 0.8°C in January to 19.7°C in August. Thus, January is the coldest month, with average minimums dropping to -1.7°C and maximums rarely exceeding 3.3°C. The warmest months are July and August, with average temperatures around 19.6°C - 19.7°C. During these summer months, daytime highs reach a pleasant 24.3°C - 24.5°C.

The summer period in Passau, spanning June, July, and August, offers comfortably warm weather. Daytime temperatures usually fluctuate between 23-25°C, creating ideal conditions for walking and sightseeing. Nights bring a pleasant chill, with temperatures around 13-15°C. The difference between day and night temperatures in summer can be quite significant, reaching about 10°C, which ensures a comfortable night's sleep after a hot day. The spring months, April and May, show gradual warming, with average temperatures from 9.6°C to 13.3°C, and are also characterized by notable daily temperature fluctuations.

Winter in Passau, especially in December and January, is quite cool. Average temperatures hover around freezing, with frequent nighttime frosts when the mercury drops below 0°C (for example, to -1.7°C in January). Daytime temperatures in the coldest months rarely rise above 3-4°C. February brings a slight warming, with an average temperature of 2.7°C. Daily temperature fluctuations in winter are less pronounced than in summer but still noticeable, at approximately 5-7°C. The autumn months, September and October, are transitional, with temperatures gradually decreasing from an average of 15°C in September to 11.1°C in October.

Precipitation in Passau is distributed fairly evenly throughout the year, with no pronounced rainy or dry season in terms of total volume. The amount of precipitation varies slightly from month to month, remaining at a relatively low level.

The highest amount of precipitation, according to monthly averages, falls in December (about 4 mm); this month also sees the highest number of days with precipitation—averaging 16. The periods with the least precipitation (around 2 mm per month) occur in February, March, April, October, and November. Meanwhile, the fewest rainy days (about 11) are recorded in April and October. Overall, precipitation occurs regularly throughout the year, with "wet" days ranging from 11 to 16 per month.

The nature of precipitation changes by season. In winter, especially in January (average temperature 0.8°C, 15 days of precipitation) and December (average temperature 1.7°C, 16 days), it often falls as snow due to the cold temperatures. February can also bring snowfalls, though rain is possible. With the arrival of spring and through the summer months (June, July, August), when temperatures are much higher, precipitation falls exclusively as rain. In autumn, as it gets colder, rain may gradually turn into sleet, particularly in November. Given the low total rainfall despite relatively frequent occurrences, it can be assumed that these are often light, perhaps drizzling rains or short showers, rather than prolonged downpours.

When planning a trip to Passau, it's important to consider the variable weather typical of this region of Germany. Layering should be your key packing principle, as temperatures can change throughout the day. Regardless of the season, you'll need comfortable shoes for walking along the city's cobblestone streets. Given that an average of 11 to 16 days per month may see some precipitation—even if not always heavy (2-4 mm)—a light folding umbrella or a waterproof windbreaker will be reliable companions. In spring (March-May) and autumn (September-November), the weather can be particularly unpredictable, with average temperatures ranging from 5°C to 15°C. During these periods, it's worth bringing both light sweaters and warm jumpers, as well as a mid-season jacket.

In summer, from June to August, Passau is usually warm, with an average temperature of around 18-20°C and highs that can reach 23-25°C. For this time of year, light clothing, T-shirts, shorts, and sundresses are suitable, along with sunscreen and a hat. However, even summer evenings can be cool, and brief showers are possible, so a light jacket or cardigan won't go amiss. Winter (December-February) in Passau is chilly, with average temperatures around 0-3°C, sometimes dropping below freezing. For a winter trip, be sure to pack warm outerwear (a down jacket or winter coat), a hat, scarf, gloves, and several layers of warm clothing, such as fleece jackets and thermal wear. Waterproof shoes will also come in handy, especially in December when precipitation can be slightly higher and sleet is possible.
