Climate Overview Practical

Washington County Has a Long Growing Season and Wet Climate

Roughly 277 days pass between the last frost and the first one here — long enough to put in warm-season crops and still squeeze a second planting out of the year. The climate is humid subtropical: about 40 inches of rain on average, January lows down around 39 degrees, July highs pushing 96. Gardeners get a generous window; the trade-off is summers that bake.

The same rainfall that feeds the growing season collects in the Blackland Prairie clay, which holds water the way a bowl does. On rural land that shows up as standing pools and a driveway that turns to gumbo after a storm. Walk a parcel the day after a hard rain and you will see exactly where the water wants to sit before you ever sign for it.
