Long dry season “trek” ahead

You know how a mountain peak seems
impossibly far off when you start a hike?

That’s where we’re at right now in our dry season cycle.

The blue curve on the above graph shows the running 7-day running rain total for Big Cypress Nat’l Preserve from Apr 2014 to present.  The black line shows the 7-day median running rain total, as calculated from 2000 to present.  Background color coding shows the length of the summer rainy and winter dry seasons.  Points of interest: (1) Can you see the rainiest point in this past year’s rainy season? – early August. (2) During the middle of the dry season (December through February) cooler temperatures cause the drop of the water table to slow down.  (3) It isn’t until the end of the dry season (St. Patrick’s Day to Memorial Day) that increasing daylight hours and rising temperatures push the water cycle into deep drought mode.  That’s when timely spring rains are most critical. 

Or in other words, we have a long 7-month trek through mostly sunny skies and a slowly subsiding water table.  If unchecked by timely rains, wildfires may even be in the mix towards the end, by month six or seven.

That’s when the mountainous wet season clouds will start to reappear again, too.

Who said south Florida was flat?
