But one thing to note is that away from the mountains, this isn't
really as rainy a country as we tend to think: it's just that it can
happen at any time of year. Ask anybody how many times they get rained
on while walking from the station to the office, and both you and they
might be surprised to find how dry it usually is. It rains more in
Sydney than in Carmarthen, for example, and far more in New York City
than in London: the catch is its tactless timing, and there can be
long periods of rainless grey skies.

That is true, but there is another factor - outside high summer,
there is very little evaporation, due to the weak sunlight and
(in winter) short days.
