Best time to visit Frankfurt am Main

Frankfurt am Main is a city of two halves. September scores 84 and December scores 26 — a 58-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. The good window runs May to September — 5 months within ten points of the best.

July is the warmest month at 27 °C and January the coolest at 3.9 °C — a 23.1 °C spread across the year. At the other end, 81 nights a year fall below freezing: the winter here is a real one.

There is a real wet season here. July, August and December carry the rain — up to 14 wet days in a month — while March, April and September drop as low as 9. That 5-day gap is the biggest single difference between a good month and a bad one in Frankfurt am Main, and it moves further than the temperature does.

Daylight swings hard — 16.4 hours at midsummer against 8.1 at midwinter. That 8.3-hour difference changes how much fits into a day more than the temperature does.

The three strongest months are September, June, May. The one to think twice about is December. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
