Hailing from the U.K, I thought I understood the character of a rainy place.
But Amsterdam lies to the east of miles upon miles of unbroken North Sea and enjoys a westerly prevailing wind.
This makes the weather highly variable; one would be wise to take an unbrella out for the day even with the bluest of skies above. Within half an hour the weather can, and often does, switch from nice to downpour and back again.
The Dutch have a great word for this: wolkbreuk; literrally ‘cloud burst’.
