Cologne comes with its natural season cycle; the summers can get really hot and the winters, really chilly. In spite of the extreme weather, Cologne is seen welcoming tourists all around the year. The ideal time to visit the city would be September and October, just as autumn is beginning to set in. Considered to be the peak season, expenses will sky-rocket, so if you’re looking to travel on a budget, book well in advance. Bring your umbrellas with you it can rain at the drop of a hat.
For those of you who can take the heat better than the cold, May is the month for you. Beer gardens throw open their gates and the weather is moderately pleasant, but it can get humid once the afternoon sets in. The nights offer a respite as the temperatures come down.
