Tough Conditions for Noble County Lawns
A lawn difficulty score of 43.7 makes Noble County one of the more challenging regions for turf management in the state. This score is significantly lower than the national median of 50.0, requiring extra effort from residents.
High Heat and Moderate Rain
With 76 extreme heat days, Noble County matches the state average for intense summer sun. The 36.2 inches of annual precipitation is just enough to meet the 30-50 inch ideal range, but leaves little margin for error during hot spells.
