Kodiak Island weather is maritime — wet, windy, and cool, with fronts moving through the Gulf of Alaska on their own schedule. If you come here, you plan around the weather, not the other way around.
Temperatures
- Summer highs (June–August): 55–65°F, lows in the upper 40s.
- Fall (September–October): 40s–50s, cooling steadily.
- Winter (November–March): highs in the 30s, lows in the 20s. Wind chill worse.
- Spring (April–May): mid-30s to mid-50s.
Rain, fog, and snow
Kodiak town averages roughly 75 inches of precipitation per year, spread across ~200 wet days. Some parts of the island are even wetter. Fog is common in summer; snow shows up mostly November through March at sea level and hangs longer at elevation.
Wind
Wind is the defining feature. Gales are routine, especially in fall and winter. Yacht anchorages are picked specifically to sit sheltered from the prevailing wind. Small boat operations pause when it's blowing hard.
How weather shapes trips
- Flights: commercial jets to Kodiak can cancel for fog. Float planes to the bays cancel more often.
- Boat travel: operators pick anchorages based on the forecast. Hunts and fishing plans shift by the day.
- Deer hunting: weather is often a feature, not a bug. Snow drives late-season bucks to the beach.
What to pack
- Serious waterproof shell (top and bottom), not a "water-resistant" jacket.
- Insulated mid-layers, wool or synthetic.
- Waterproof knee-high boots.
- Gloves and a warm hat, even in summer.
- Dry bags for everything.
