Steady Precipitation and Moderate Summer Heat
With 33.5 inches of annual precipitation, the county sits right in the ideal range for healthy turf. While there are 9 extreme heat days per year—slightly more than the state average of 7—the 2,637 growing degree days support consistent grass growth.
Ideal Soil pH for Low-Maintenance Lawns
The soil pH of 6.81 is nearly perfect, falling directly within the 6.0-7.0 ideal range for most turfgrasses. This loamy soil is 59.3% sand and 13.7% clay, providing moderate drainage that rarely requires heavy amendments.
