USA Crop Circle Formations - Statistics
Note: These charts begin to answer the question "During what time of the year are crop circles being most reported?" What this chart shows is that crop circles in the USA have been reported in every single month throughout the year, and are not confined to the summer growing season. Of course, the peak growing and harvest season of summer (June-July-August) in the northern hemisphere has recorded the most reports, but May, September, and October have also reported significant numbers of reports. It is interesting to note that October has recorded slightly more reports than September - primarily due to the number of late season crop circles being found in cattle corn. The winter months of December-January-February have recorded a number of reports of ice circles which are also included here.
