Procrastination of the pineland peak?

Meterologically, the wet season is 2 months old.

Why then are the pinelands still waiting for it to begin?

The above chart shows total time (in months)
that the hydric and mesic pinelands were flooded
each year in Big Cypress Nat'l Preserve, 1991 to present

Answer:

Swamp stage hasn't risen high enough (yet) to inundate the roots of the hydric pinelands or surround the mesic pine islands with its shallow sea-like moat. On average, or at least over the past 20 years, hydric pinelands (orange) in Big Cypress National Preserve get wetted above their roots for 3-5 months per year, whereas the higher elevated mesic pines (red) get shallowly inundated for 2-4 weeks.


Not to worry.

The arrival of water peaking in the pines isn't late yet.

This calendar graph provides you a full historical
timeline of swamp stage, from 1991 to present.

Peak water conditions are represented by hues of blue.


But it isn't early either. In 2003, the swamp rose into the hydric pines by late May and in 2005 the mountainous-by-swamp-standards mesic pines were submerged by mid June. In comparison, the last few years have been slow to peak -- we have to go all the way back to 2009 to find a year when the pinelands were flooded in July.

What year had the latest pineland peak?


Answer: The year 2000 (in early September).

That gives us seven weeks.
