The field drains extremely rapidly and Two years back (when most of the country was flooded) is the only occasion I am aware of that the field has been closed, and even then, it could still be used by tents. It was only the Big things such as caravans and campers which had to be located off-site.
I don't see anything to suggest weather comparable to then.
Quack!
