It was our third of the water year (i.e. since January 2021) …
And second of the wet season.
What is a Big Rain Day (BRD)?
It’s any day when south Florida averages an inch or more of rain across the entire peninsula.
On average, south Florida gets about 5 BRDs per year. Flood years we typically get more (i.e. 10 in 2005, the year of Wilma) and drought years get less (i.e. 2 in the 2011, the year of the Jarhead Wildfire).
What months do BRDs strike most?
Almost 20 percent of them occur in June. But the take-home lesson from the table below is that practically every month has at least a 1 in 30 chance of getting a BRD. And that’s all it takes. A single day of rain can change the outlook for the whole month, or longer.
Tuesday’s BRD wasn’t gargantuan …
But it did set the stage for the high-water heart of the wet season ahead.
Water typically peaks in September and October in the swamp.
