August isn’t, and shouldn’t even be a consideration. I usually prep fields in August with herbicide if it’s needed, but never plant before the third or fourth week in September. I prefer to wait until October. Remember, September and October are the two driest months of the year in AL. Getting a fall crop to germinate in 90+ degree heat in late August to early September, followed by an average of 2.5-3.5” or rain for the next two months is not a reasonable expectation for success.
