Events take place throughout the year, so there is no bad time to visit, but the weather may be best in the shoulder seasons of spring (frühling) and fall (herbst). The very best time to visit Frankfurt is in October, the month of the Frankfurt Book Fair. Frankfurt is also the perfect central location to explore the rest of the country with its superb connections by road and rail.
Here is a complete guide to the best time to visit Frankfurt with information on weather, events, and festivals.
Weather in Frankfurt
Frankfurt isn't known for its great weather, but there are plenty of warm, sunny days. The city has a temperate oceanic climate and four distinct seasons.
After a long, cold winter, Frankfurt is so ready for spring (frühling). As sunshine starts to pierce the cloud cover, temperatures quickly rise to 50 to 65 degrees F. There are still rainy days, but the chill is leaving the air.
During summer, Frankfurt is one of the warmest places in the country with temperatures averaging around 75 degrees F but can reach the high 90s F. Frankfurt has better air conditioning than much of the country, but it is still relatively rare. June is the sunniest month of the year, but never rule out the rain. Autumn (herbst) is when things begin to cool down. Temperatures range from the low 40s to high 50s F until the real cold of late November when the wind picks up, and snowflakes can fly.
Temperatures can drop below freezing in the heart of winter. Average lows dip down to 25 degrees F, and snow usually happens several times in the season, although it doesn't often accumulate. Ice is widespread, so bring slip-proof boots and be careful driving. Make sure to pack your winter gear, particularly if you want to get out of the city and enjoy some winter sports.
Popular Events and Festivals in Frankfurt
