Data Story
About Lawn Care in Kodiak Island Borough, Alaska
Island Living Means Stable Lawn Care
Kodiak Island Borough has a lawn difficulty score of 53.8, placing it above the national average for ease of maintenance. This score reflects a maritime climate that avoids the extreme temperature fluctuations found on the mainland.
Bountiful Rain and Cool Summers
Kodiak receives 80.5 inches of annual precipitation, which is well above the national ideal but keeps lawns consistently lush. The growing season is moderate, starting after the May 9 frost and ending around October 4.
Preparing Kodiak's Maritime Soil
Data on soil pH and texture is currently limited, making individual soil tests the best way to plan your amendments. In this 80-inch rainfall environment, ensure your soil foundation has the drainage capacity to handle heavy island storms.
Occasional Dry Spells on the Island
Kodiak has experienced zero weeks of true drought in the past year, though 2.5% of the area is currently classified as abnormally dry. These dry patches are rare and usually short-lived, as the island's maritime weather provides frequent moisture.
Planting for the Kodiak Climate
With 407 growing degree days, grass grows at a slower, steadier pace than on the mainland. Seed your lawn in mid-May once the frost risk passes to allow the roots to settle before the heavy autumn rains arrive in October.
