Cool summers (July averages 75.2°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 11; this is the best renovation window. Cool winters (January averages 22.1°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
Moderate rainfall (28.6 inches) means lawns benefit from weekly deep watering during summer stress. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor.
