The climate in Hanover is temperate, with four distinct seasons. It is characterized by relatively mild winters and warm summers, without extreme temperature fluctuations. The weather here can be quite changeable, so travellers should be prepared for various conditions throughout the year.

Summer in Hanover is usually warm and pleasant, with average temperatures in July and August around 18-19°C, and maximum values reaching a comfortable 23-24°C. Winters are cool, but not severe, with average temperatures around 3-4°C in January and December. Spring and autumn are classic transitional seasons with gradual temperature increases or decreases. Precipitation in Hanover falls quite evenly throughout the year, with a small amount (2-3 mm per month), however, the number of days with precipitation is quite high (from 10 to 16 days per month). This suggests that rains, although not heavy, occur frequently.

Hanover experiences a temperate climate with noticeable seasonal temperature variations. The annual temperature range is quite wide: the coldest months are January (average temperature 3.5°C, minimum 1.5°C) and February (average temperature 4.3°C, minimum 1.2°C). The hottest month is usually August, when the average temperature reaches 19.4°C, and maximum values can rise to 24.0°C. July is also characterized by warm weather with an average temperature of 18.7°C and a maximum of up to 23.2°C.

The summer months in Hanover, from June to August, are characterized by pleasantly warm weather. Average maximum daily temperatures range from 22-24°C, creating comfortable conditions for walking and outdoor activities, while average temperatures are 18-19°C. Nights bring refreshing coolness, with temperatures around 13-15°C. Winter, covering the period from December to February, is quite mild in Hanover, but cool. Average temperatures stay just above zero (3.5-4.3°C), with minimum values around 1-2.5°C and maximum daily temperatures usually not exceeding 5-7°C. Frosts are possible, but severe cold is atypical.

Temperature differences between day and night are most pronounced in late spring and summer, when the difference between the average maximum and average minimum temperature can be around 9-10°C (for example, in June from 13.3°C to 22.8°C). In the winter months, these fluctuations are less significant, usually within 4-6°C. Spring and autumn are transitional seasons with gradual temperature changes, offering mild weather, especially in April-May and September-October, when average temperatures vary from 9.4°C to 15.6°C.

In Hanover, precipitation is distributed quite evenly throughout the year, and there is no clearly defined rainy season or dry period. The total amount of precipitation per month is small, mostly around 2 mm, and only slightly increases to 3 mm in February, July, and December. This suggests that heavy downpours are not characteristic of Hanover; rather, one can expect frequent but moderate drizzle or light rain.

The highest frequency of precipitation is observed in the winter months: January and December can boast an average of 16 days with precipitation. October also stands out with increased humidity with 15 rainy days. February (3 mm of precipitation, 14 wet days) and July (3 mm of precipitation, 13 wet days) can also be classified as periods with more frequent precipitation. Overall, precipitation in Hanover falls regularly throughout the year.

The "driest" month in terms of precipitation frequency is September, when there are on average only 10 days with rain, although the volume of precipitation remains at the level of 2 mm. April and June are also characterized by fewer rainy days — about 11. Given the low average temperatures in the winter months (especially in January and February, when minimum temperatures drop to 1.2-1.5°C), precipitation during this period may fall as snow or sleet, although the total amount remains small.

When planning a trip to Hanover, it is important to consider the changeable weather and frequent precipitation throughout the year. Indispensable companions will be a waterproof jacket or raincoat, as well as a compact umbrella, since the number of rainy days is quite high (from 10 to 16 per month), even with a small total volume of precipitation. Comfortable walking shoes are another mandatory item on your list, as the city is conducive to long walks. The principle of layering in clothing will help you easily adapt to temperature changes during the day, which is especially relevant for Germany.

In the summer months (June-August), the weather in Hanover is usually warm, with an average temperature of around 18-19°C and highs of up to 22-24°C. You will need light items: t-shirts, shorts, dresses. However, do not forget a light jacket or sweater for evening walks or cooler days, as well as sunscreen. In winter (December-February), the average temperature hovers around 3-4°C, so a warm down jacket or coat, sweaters, hat, scarf, and gloves are necessary. Waterproof and warm shoes will also be very useful, considering possible precipitation and low temperatures.

For spring (March-May) and autumn (September-November) trips to Hanover, the "layering" strategy works best. Temperatures during these periods vary from cool to moderately warm (averaging from 6°C to 15°C). Bring items that are easy to combine: t-shirts, long-sleeved tops, a fleece jacket or cardigan, as well as a mid-season jacket, preferably waterproof. This will allow you to feel comfortable both on sunny warm days and in the cooler and windy weather characteristic of the off-season in Hanover.
