Perfectly-timed rain

It's often not how much ...

But when you receive dry season rain.

The above chart shows the history of April rainfall totals for Big Cypress National Preserve from 1970 to present

April is a perfect case point.

No rain in April almost always spells drought. Evapotranspiration (left alone) is just that strong. Last year saw record April rain (around 5 inches). This year so far we've recorded just under two. That's not enough to re-flood the swamp, but it is just enough to help keep deep drought at bay.

May's 4.5 inch monthly rain average is deceiving. Most of it usually comes in the month's final half. Thus, the first half is an extension of mostly dry-sky April.
