Imagine living in a town where the rain doesn't just fall—it lives there. That’s the reality of the weather in Whittier AK, a place so damp and dramatic it makes Seattle look like a sun-scorched desert. Honestly, if you’re planning a trip here, you’ve gotta prepare for a microclimate that behaves more like a tropical rainforest than an Alaskan port, except it’s roughly $40^{\circ}$ colder.
Whittier sits at the end of Passage Canal, tucked into a deep fjord. It’s basically a funnel for every storm brewing in the Gulf of Alaska.
Because of those 3,500-foot peaks surrounding the town, clouds get trapped. They just sit there. And then they dump. We’re talking about an average of 197 inches of precipitation a year. To put that in perspective, that’s over 16 feet of water falling from the sky. Most places in the Lower 48 struggle to hit 40 inches.
The Rain, The Snow, and the One-Building Solution
You might have heard that almost everyone in Whittier lives in a single 14-story building called Begich Towers. That isn't just a quirky local fact; it’s a direct response to the weather in Whittier AK. When the wind is screaming at 60 mph and the snow is piled halfway up the first floor, nobody wants to commute.
Even the school is connected to the towers by an underground tunnel. Kids literally walk through a concrete tube to get to class so they don't get blown away or soaked to the bone.
Winters are long. Really long.
Snow usually starts piling up in late October. By January, the town is often buried under a literal mountain of white. While Anchorage—just an hour and a half away—might get a respectable 75 inches of snow a season, Whittier gets hammered with an average of 250 inches.

The wind is the real kicker, though. Local winds, often called "williwaws," can gust up to 80 mph. These aren't your average breezes. They’re violent, erratic gusts that come tumbling down the mountainsides.
Breaking Down the Seasons (Sorta)
There aren't really four seasons here. It’s more like "Deep Winter," "Muddy Spring," and "Wet Summer."
- Winter (November–March): This is the season of darkness and accumulation. Temperatures hover between $20^{\circ}F$ and $30^{\circ}F$. It’s rarely "Arctic cold" like Fairbanks, but the humidity makes the cold seep into your bones.
- Spring (April–May): This is the driest time of year, but "dry" is a relative term. You’ll still see rain about 15 days a month. May is actually the best month to visit if you want to see the sun for more than five minutes.
- Summer (June–August): It’s green. Violently green. The temperate rainforest thrives on all that moisture. Highs usually peak in the low $60^{\circ}sF$. It’s beautiful, but you’ll still be wearing a raincoat 70% of the time.
- Fall (September–October): This is the wettest window. September alone can see over 20 inches of rain. The storms coming off the ocean are relentless.
Why the Military Picked This Gloomy Spot
The weather in Whittier AK is actually the reason the town exists. During World War II, the U.S. Army needed a secret, ice-free port. They chose this spot specifically because it’s almost always covered in a thick blanket of fog and clouds.
They figured if the Japanese tried to bomb it, they wouldn't even be able to find it.
The mountains act as a natural fortress, and the deep water of the fjord stays ice-free year-round due to the churning currents and salt content. It was a strategic masterstroke built on bad weather. Today, that same fog is what makes the town feel so eerie and isolated, especially when you realize the only way in by land is a 2.5-mile long, single-lane tunnel that closes at night.

Survival Tips for the Whittier Microclimate
If you're heading down the Portage Glacier Road to visit, don't trust the forecast for Anchorage. They are two different worlds.
First off, buy a real raincoat. I don't mean a cute windbreaker. I mean a heavy-duty, rubberized Helly Hansen or Grundéns style jacket. If the fabric says "water-resistant," you’re going to get wet. You need "waterproof."
Cotton is your enemy here. Once it gets wet—and it will—it stays wet and saps your body heat. Stick to wool or synthetics.
Also, check the tunnel schedule. The Anton Anderson Memorial Tunnel is a shared rail and vehicle bridge. If the weather is particularly nasty, or if there's a heavy snow load on the mountains, the tunnel can occasionally close for avalanche mitigation. Always have a backup plan or enough snacks to wait out a two-hour delay.
The Impact on Daily Life
Living with this much moisture changes things. Everything rusts. Wood rots if it isn't treated every single year. Mold is a constant battle for the residents of Begich Towers.

But there’s a trade-off.
The waterfalls are insane. Because it rains so much, the mountains surrounding the town are covered in hundreds of silver ribbons of water. On a rare sunny day, the contrast between the deep blue of the Prince William Sound and the emerald green of the cliffs is arguably the best view in Alaska.
Most people just hunker down. There's a reason the general store, the post office, and the clinic are all inside the same building. It's a bunker mentality. You learn to appreciate the "small" weather—the way the mist hangs low over the abandoned Buckner Building or the sound of the rain hitting the metal roofs of the harbor.
Actionable Steps for Your Visit
To make the most of the weather in Whittier AK, follow these practical steps:
- Monitor the NOAA Marine Forecast: General weather apps are often wrong about Whittier. Use the National Oceanic and Atmospheric Administration's marine forecast for Passage Canal to get the most accurate wind and precipitation data.
- Pack "Xtratuf" Boots: These are the unofficial "Alaskan Sneakers." They are neoprene boots that provide grip on slick docks and keep your feet dry in three inches of standing water.
- Time Your Trip for May or June: Statistically, these months offer the highest probability of clear skies. You’ll have more daylight and less chance of a total washout.
- Check the Tunnel App: Download the "Whittier Tunnel" status app or check the Alaska Department of Transportation website before you leave Anchorage to ensure the road is open.
- Don't Let Rain Stop You: If you wait for a sunny day to go kayaking or take a glacier cruise, you might never leave your hotel. The glaciers actually look more blue on overcast days. Embrace the "Whittier Wash."
