For a May trip to Juneau, pack versatile layers for cool and often wet conditions with temperatures between 41°F and 55°F, including a waterproof jacket for boat tours in areas like Tracy Arm Fjord where you'll encounter cold sea spray. A fleece, comfortable hiking pants, and waterproof shoes are also essential. May marks the true start of the visitor season, but cool, rainy weather is still very common.

Based on typical May conditions in Juneau. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
May in Juneau is a vibrant month as spring takes hold, the rainforest turns a brilliant green, and the tourist season begins to ramp up. The days are long and bright, and attractions like the Mount Roberts Tramway typically open, offering stunning views of the still snow-capped peaks. This is a fantastic time for wildlife viewing, with activity increasing along the shores of the Gastineau Channel and in the surrounding forests. Despite the feeling of spring, a frequent visitor mistake is to pack for a typical spring vacation. The weather remains highly unpredictable, and a sunny day can quickly give way to a cold, drizzly afternoon. Underestimating the chill on the water during a whale-watching tour or the cold wind near the Mendenhall Glacier can lead to an uncomfortable experience. A windproof, waterproof layer is your most important piece of clothing.
A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.
A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.
An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.
A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.
Dress in adaptable layers. A combination of t-shirts and long-sleeved shirts, a fleece jacket or vest, and a reliable waterproof and windproof shell will serve you well. Pack comfortable pants (hiking pants or jeans) and bring a warm hat and a pair of light gloves, especially for boat tours or glacier viewing. Always be prepared for rain.
May is an excellent time to visit Juneau. It's the start of the summer season, so most tours are running, but the biggest crowds have yet to arrive. You'll enjoy long daylight hours and the beauty of the awakening landscape. While you should expect rain, May is statistically drier than the late summer and autumn months.
Waterproof shoes are a must. Waterproof hiking boots are ideal if you plan to hit the trails, which will likely be muddy. At a minimum, bring waterproof walking shoes with good traction for exploring the town and its surroundings. Your feet will thank you after a day of walking through inevitable puddles.
May in Juneau is cool, with average high temperatures of 55°F and lows around 41°F. While it can feel pleasant in the sun, it will feel chilly in the shade or when the wind picks up. Expect precipitation on about 17 days of the month, so cool and damp is the general rule.
Binoculars are a must-have for spotting whales, eagles, and bears. Pack sunscreen and sunglasses, as the sun can be surprisingly strong with the long daylight hours, especially when reflected off water or snow. An eye mask can be helpful for sleeping when it stays light late into the evening.
