“Maart roert zijn staart”.
A typical Dutch saying about the wheather in March.
It could be translated in English like this:
“March is shaking its tail”.
Which means that
during the last days of the month March,
the wheather might behave like in autumn:
stormy winds, grey skies
pouring showers of rain.
And that’s how the end of March is,
right now, here in the Netherlands.
