The possibility for frost in the Tri-State rises from mid-September through early October. Our first light frost (a low temperature around 38\u00b0) of the season usually occurs in early October but has occurred as early as mid-September.<\/p>\n

Frost is more likely when the air temperature drops to or below 36\u00b0. The average date for the first fall morning in Cincinnati with a temperature of 36\u00b0 or lower is in early to mid-September. A damaging frost, however, can happen as early as late September.<\/p>\n

Here’s some perspective on fall frost dates in Cincinnati:<\/p>\n

The “average” above uses temperatures data from 1981 to 2010, and the “long-term average” uses temperature data from 1871 to 2012.<\/p>\n

A morning with temperatures to or below 32\u00b0\u00a0 – as known as a “freeze” – first occurs in late October, on average. A freeze often signals the end of the growing season for most plants. The first “hard freeze” (low temperature of 28\u00b0 or below) of the fall in Cincinnati typically occurs in early November. With the exception of hardiest and herbaceous crops, any plants that are able to survive a freeze will likely be killed in a “hard freeze.”<\/p>\n

If left outside, your plants will likely have a couple of weeks left before getting their first taste of fall frost. The latest ECMWF Weekly model run suggests late September will be near or warmer than average. I suspect our first frosts of the year will come in early to mid-October this year…right on schedule.<\/p>\n","protected":false},"excerpt":{"rendered":"
