The climate in Frankfurt am Main can be described as temperate, with four clearly defined seasons. This means travellers can expect noticeable weather changes throughout the year, making each season attractive in its own way for visiting this city in Germany.

Summer in Frankfurt is generally warm and pleasant, with peak temperatures in July and August, when averages hover around 20°C and maximums can reach 25°C. Winters here are cool, with average temperatures just above zero degrees Celsius, especially in January and December, which also see the highest number of days with precipitation. Spring and autumn are transitional seasons with mild and gradually changing weather, ideal for walking and exploring the city.

A specific feature of the weather in Frankfurt am Main is the relatively even distribution of precipitation throughout the year, judging by the number of rainy days. Although the data indicates a small amount of rainfall in millimetres monthly, the number of days when precipitation is possible varies from 10 to 16 per month. This suggests that light rain or drizzle can catch you at any time of the year, so having an umbrella or a light raincoat would not be amiss when planning your trip.

The annual temperature progression in Frankfurt am Main demonstrates typical features of a temperate climate with distinct seasons. The hottest month is usually August, when the average air temperature is 20.2°C, and daytime maximums reach an average of 25.1°C. July is also very warm, with an average temperature of 19.8°C and a maximum of 24.7°C. Conversely, the coldest month is January, when the average temperature drops to 2.8°C, and the average minimum night temperature is only 0.7°C. December is not much warmer, with an average temperature of 3.6°C and a minimum of 1.5°C.

The summer months, from June to August, in Frankfurt am Main delight with pleasant warmth. Average maximum daytime temperatures during this period range from 23.7°C in June to 25.1°C in August. Nights bring refreshing coolness, with minimum temperatures varying from 13.7°C in June to 15.4°C in August. This creates noticeable diurnal temperature fluctuations reaching about 10°C, making evenings comfortable for relaxing after the daytime heat. May, with a maximum temperature of 18.3°C, serves as a pleasant transition to the summer season.

The winter period, covering December, January, and February, is characterised by cool weather, but without severe frosts. Monthly average temperatures in these months range from 2.8°C in January to 4.1°C in February. During the day, the thermometer usually rises to 4.9°C - 7.4°C, while at night the temperature often drops close to the freezing point or slightly below, averaging 0.7°C - 1.5°C. This means that night and morning frosts are quite likely. The difference between day and night temperatures in winter is smaller than in summer, amounting to approximately 4-7°C.

In Frankfurt am Main, a small amount of precipitation falls monthly, mainly between 2 and 3 mm. Despite these low figures for total moisture volume, the frequency of days with precipitation varies noticeably throughout the year, indicating the absence of a distinct dry season, but suggesting frequent rather than intense precipitation.

The highest number of days with precipitation traditionally falls in the winter months. Thus, in January and December, an average of 16 wet days is recorded, with the monthly rainfall amounting to 3 mm during these periods. Given the winter temperatures (average January temperature 2.8°C, December 3.6°C, with minimums dropping close to zero), precipitation at this time of year can fall not only as light rain or drizzle but also as sleet or snow, especially on the coldest days.

In the remaining months, from February to November, the average amount of precipitation holds steady at 2 mm per month. The number of days with precipitation during these periods varies: the lowest frequency is observed in June and September (10 days each), while in other spring, summer, and autumn months, this figure fluctuates between 12 and 14 days. This suggests that even in the warm season in Frankfurt am Main, frequent but typically short and non-intense precipitation is likely, most often in the form of light rain. Thus, despite the small total amount of precipitation, having a light umbrella or raincoat will be a useful addition to your luggage at any time of the year.

When packing your suitcase for a trip to Frankfurt am Main, it is worth remembering its temperate climate with distinct seasons and frequent, albeit not heavy, precipitation. The key principle should be layering in clothing, which will allow you to feel comfortable with temperature changes throughout the day. Be sure to take comfortable shoes for walking around the city, as exploring its beauties is best done on foot. And, of course, do not forget an umbrella or a light raincoat – they will come in handy at any time of the year, as the number of days with precipitation here is quite stable, ranging from 10 to 16 per month.

In the winter months (December-February), when the average temperature hovers around +2°C...+4°C and night frosts are possible, you will need a warm jacket or coat, hat, scarf, and gloves. In spring (March-May) and autumn (September-November), the weather is mild but changeable, so sweaters, cardigans, and a mid-season jacket will be the ideal choice. For the summer months (June-August), when the average temperature rises to +18°C...+20°C, and the maximum can reach +25°C, pack light clothing: t-shirts, shorts, dresses. However, do not forget a light jumper or jacket for cool evenings, as well as sunscreen and headwear for protection from the sun on clear days.
