Ketchikan, Alaska, sits in a temperate rainforest climate where the average temperature reflects the moderating influence of the Pacific Ocean. Located at the southernmost tip of the Tongass National Forest, this coastal city experiences milder winters than interior Alaska and cooler summers than the state’s continental regions. Understanding the specific averages throughout the year is essential for visitors planning fishing trips, hiking excursions, or cultural tours through the historic Creek Street district.
Year-Round Temperature Patterns
The average temperature in Ketchikan follows a pattern typical of maritime climates, with relatively small extremes between the coldest and hottest months. Winter averages stay above freezing, while summer averages remain comfortable rather than hot. This stability creates an environment where rainforest vegetation thrives and outdoor activities are viable for much of the year. Travelers often find the persistent coolness and moisture require layered clothing and waterproof gear regardless of the season.
