You’re probably picturing Sitka as a frozen wasteland where you’ll need a dogsled to get to the grocery store. Honestly, that couldn’t be further from the truth. Nestled on the outer edge of the Inside Passage on Baranof Island, Sitka is basically the "banana belt" of Alaska. It’s a temperate rainforest, which means it’s more likely to be damp and misty than buried under ten feet of snow.
Right now, if you’re looking at the weather forecast for Sitka Alaska, things are looking pretty typical for mid-January. We’re seeing a current temperature of 43°F. It feels like 39°F, mostly because of that 81% humidity that just kinda clings to you. The wind is a gentle 6 mph coming from the southeast. It’s cloudy—shocking, I know—and there’s about a 10% chance of rain today.
Why the Forecast Isn't as Scary as You Think
Most folks see "Alaska" and panic-buy a parka rated for the South Pole. Don't do that. Sitka’s climate is maritime, meaning the Pacific Ocean acts like a giant space heater. While the rest of the state is dealing with sub-zero temps, Sitka is sitting pretty with highs in the 40s.
Take a look at the week ahead. Thursday and Friday are staying steady with highs around 44°F to 47°F. Even the lows are barely dipping to 40°F. You’ll see "cloudy" or "mostly cloudy" on almost every single day of the weather forecast for Sitka Alaska this week. That’s just the vibe here. It’s moody. It’s grey. It’s beautiful in a way that makes you want to drink way too much local coffee.
The Rain: A Local Love Affair
If you hate rain, Sitka might test your patience. We get about 86 inches a year. To put that in perspective, October alone can dump nearly a foot of water on the town. But here's the thing: it’s rarely a torrential downpour. It’s more of a persistent, fine mist that Alaskans call "liquid sunshine."
- January Reality Check: You’re looking at highs of 40°F and lows of 32°F on average.
- Precipitation Patterns: It rains about 230 days a year. You just gotta get used to being a little bit damp.
- The Snow Factor: We do get snow, maybe 33 inches a year, but it usually melts within a day or two because the salt air is so mild.
The weather forecast for Sitka Alaska for the next ten days actually shows a transition from rain to potential snow showers toward the end of next week. By Saturday, January 24th, the high drops to 36°F with a 20% chance of snow. That’s about as "wintry" as it gets at sea level.
Dressing Like a Human, Not an Astronaut
If you show up in a heavy down jacket, you’re going to sweat. Then you’re going to get wet from the sweat. Then you’re going to be cold. It's a whole cycle.

The secret is layers. Start with a synthetic or wool base—never cotton, because cotton is a death trap in the rain. Add a fleece or a wool sweater. The most important piece of gear? A high-quality rain shell. Not a "water-resistant" windbreaker, but a real-deal waterproof jacket. Locals swear by Xtratuf boots. They’re the unofficial sneaker of Southeast Alaska. If you aren't wearing "Sitka Sneakers," everyone knows you're from out of town.
What to Actually Do When the Forecast Says "Rain"
Honestly, the rain shouldn't stop you. The Tongass National Forest is actually more vibrant when it’s wet. The moss turns this neon green that looks like it’s been Photoshopped.
Hiking the Indian River Trail is a great call if the wind isn't too crazy. It’s a 5.3-mile trek that’s relatively flat and leads to a waterfall. In the summer, this is where the salmon run, but in January, it’s just peaceful and quiet. If the weather forecast for Sitka Alaska looks particularly nasty, head to the Sitka National Historical Park. The totem poles look incredible against a grey, misty backdrop.
Surprising Seasonal Shifts
- Spring (April-May): This is actually the "dry" season. I use that term loosely. It’s the best time for wildlife viewing as the forest wakes up.
- Summer (June-August): You’ll get nearly 18 hours of daylight. Temps can hit the 60s, and on rare "bluebird" days, it might even feel hot because the sun is so intense at this latitude.
- Fall (September-November): This is storm season. If you want to see massive waves and feel the raw power of the Pacific, this is your time. Just bring extra socks.
Actionable Next Steps
Check the weather forecast for Sitka Alaska about 24 hours before you head out, but don't live by it. Conditions change in minutes. If you're packing right now:
- Ditch the umbrella; the wind will just break it anyway.
- Invest in wool socks—Smartwool or Darn Tough are the gold standard.
- Download a tide app if you're planning on beachcombing; the weather is only half the story when the tide swings can be 10 feet or more.
- Grab a waterproof case for your phone or camera because you’re going to want photos of the eagles, rain or shine.
