Considered to be the Venice of the North, Geithoorn looks beautiful any time of the year. However, July to September is the best time to visit Giethroon as the weather remains pleasant enough to take a ride on water. If you wish to avoid crowds and peak season, then October is a good time to visit but you will have to take care of the chill.
Summers(June to September): The summers are actually sweet here with average highs in the low 70s and long sunny days to make your tour a fulfilling one. Hotels remain at a premium price during this time though. During summers, there are plenty of water sports and boating and sailing activities in which you can participate.
Winters(October-February): The winters can be quite chilly here making this season an off season to visit Giethoorn. Temperatures fluctuate between 30 and 40 degrees Fahrenheit, but you can get hotel rooms at good deals during this time.
Spring(March-May): With temperatures on the rise, this is also a good time to visit Giethoorn.
