Seasonal Breakdown

Cool summers (July averages 73.8°F) reduce heat stress — maintain regular mowing and moderate watering. Aerate and overseed cool-season lawns by early fall, well before October 23; this is the best renovation window. Cool winters (January averages 26.8°F) mean slow or dormant growth; keep debris off the lawn.
Watering Guidance
With 43.0 inches of annual rainfall, established lawns typically need watering only during extended dry spells.
