Weather in Kodiak

Planning a trip to Kodiak? Check out the current weather report, detailed forecasts, and charts to ensure the weather doesn't catch you by surprise.

When planning a journey to Kodiak, you should expect a cool maritime climate typical of the southern coast of Alaska. Thanks to the ocean's influence, there are no extreme frosts here characteristic of many northern regions, yet one should not expect true heat either. The weather here is distinguished by temperature stability, though it can be quite changeable throughout the day.

Seasonal differences are mild. Winter here passes with average temperatures around zero or slightly below, making it quite bearable. Summer in this corner of the United States is cool and fresh: even during the warmest months—July and August—the air warms up to an average of +12...+13°C. This is the ideal time for active outdoor recreation without the risk of overheating.

An important feature of the local climate is the high frequency of precipitation throughout the year. According to statistics, the number of days with precipitation is consistently high—from 13 to 20 days per month, with May often turning out to be the "wettest" month in terms of rainfall frequency. Travellers are strongly advised to bring high-quality waterproof clothing and footwear, as overcast skies and drizzle can accompany you in any season.

The temperature regime in Kodiak demonstrates enviable stability, due to the constant influence of oceanic air masses. The annual range is smoothed out here: the average indicators for the coldest month, January, are -1.6°C, while at the height of summer, in August, the air warms up to an average of +12.8°C. Such data indicates the absence of extreme freezing cold or intense heat.

The summer season is characterized by moderate figures. In July and August, daytime maximums reach the +15.3°C mark, and night-time temperatures rarely drop below +10.2°C. Transitional periods also pass smoothly: in May and October, average values hold in the range of +5.6°C to +5.8°C, which requires travellers to have mid-season clothing practically all year round.

Winter months hover on the edge of the freezing point. In December and January, daytime temperatures often rise above zero (up to +1.7°C), while night-time minimums are limited to values of -2.5°C... -3.4°C. A characteristic feature of the local climate is the small diurnal temperature range: the difference between day and night indicators is only 3–5 degrees, which makes the weather predictable throughout the day.

When setting off for Kodiak, be sure to leave space in your suitcase for a high-quality raincoat and waterproof footwear. Precipitation on the island is distributed quite evenly throughout the year, so one cannot count on a distinctly dry season. Even in March, which is considered one of the "calmest" months, travellers encounter precipitation for about 13 days.

In winter, when the temperature drops below zero, rain often changes to snowfall, especially in December and January, when about 18 days with precipitation are recorded. Spring here is also quite damp: May leads the statistics for inclement weather, bringing up to 20 rainy days, making this period seem rather overcast.

Summer months bring warming but do not guarantee complete dryness: in July and August, it rains for approximately two weeks per month. Despite the high frequency, the intensity of precipitation often remains moderate, which is typical for the maritime climate of this US region. Tourists should be prepared for light drizzle or rain regardless of the season.

When packing for Kodiak, it is important to remember that the weather here dictates its own rules, remaining cool and humid practically all year round. Even in the warmest summer months, the temperature rarely rises above +15°C, so light t-shirts and shorts will hardly be useful to you. The main principle of your wardrobe is layering: take high-quality thermal underwear, fleece jackets, and warm sweaters that can easily be worn over one another, regulating heat exchange depending on the changeable conditions.

Pay special attention to protection from moisture, as precipitation falls here very often—up to 20 days a month. A standard umbrella may prove useless due to the wind, so the best choice would be a reliable raincoat, a waterproof windbreaker with a hood, and water-repellent trousers. Footwear must be comfortable, warm, and strictly waterproof; for walking on rough terrain, trekking boots with non-slip soles are ideal.

In the winter period and off-season, when the temperature drops below zero, be sure to supplement your luggage with an insulated jacket, hat, scarf, and gloves. In summer, despite the cool weather, do not neglect sunglasses and sunscreen, especially if you plan to spend a lot of time by the water or in the mountains. A waterproof cover for your backpack will also be a useful accessory to keep your belongings and electronics dry during long excursions.
