The newspapers make a big fuss about tallying annual rainfall totals in accordance with the calendar year, as measured from January 1st through December 31st …
But how much does it really mean?
Up on The Continent, your true blue hydrologists tally rainfall from October 1st through September 30th, better known among us “insiders” as the water year.
