Rain was the word of the month.
The 6.38 inches of precipitation that fell made it the wettest April on record in Buffalo. Record-keeping started in 1870.
There were 13 days with measurable precipitation in Buffalo during April. That's right about average.
Far from average, however, were the significant rain events.
There were three days with rainfall amounts over an inch. That's a new record in Buffalo.
Of the rain that fell in April, 72 percent of it fell during those three days -- April 6, 20 and 30.
Above-average precipitation during March brought the region out of an 11-month drought. But, April's record-setting rains added to excess water.
The deluges meant lots of swollen creeks and streams, wet basements and flooded farm fields across the Buffalo Niagara region.
Nearly all of April's precipitation came in the form of rain.
Only 2.3 inches of snow were recorded, which was below average for April.
