Simple rain chart

It’s about that time of the year again:

Everybody’s been pounding down my door about this year’s wet season’s total.

Simple may be an understatement.  This rain chart shows annual rainfall for all of south Florida, from 1970 to present.  Notice that the annual bars do not correspond with the calendar year (i.e. January to December) but have rather been shifted to correspond with wet and dry seasons instead.  Cool colors depict wet season months and warm colors depict the dry season months.  Individual months are also depicted by variations in within-color shading.  Can you find June 2005?  That was one of south Florida’s biggest rain months on record.  Not surprisingly, that wet season recorded 45 inches of rain.

Okay, I’ll admit:

Politely knocking is closer to the truth.

Keep in mind (1) we still have a solid three weeks of “core” wet season left and (2) I don’t close the door on counting wet season rain drops until the end of October. Technically, the dry season has already started by then, but for mathe-meteorological convenience I lump all of October (just as I do all of May) as summer rain. As of today, south Florida’s totaled 35 inches. That’s just two inches below the 37 inch long-term average. But wet season rain is not all about rote totals:

Timing is essential, too.

Can you see Oasis Visitor Center?

It’s those late wet season Big Rain Days …

That delay the start of the dry season clock.
