Seattle’s late summer, particularly through August and into September, is known for generally mild, pleasant temperatures with occasional rain. Daytime highs hover mostly in the mid to upper 70s (degrees Fahrenheit), but evenings and early mornings can be a bit chilly, dropping into the 50s or 60s. Sunlight is still lively, but expect that signature Pacific Northwest soft light. The weather can change quickly—rain showers and cool breezes are always a possibility, so layering is your best friend here.
Clothing Essentials: Be Ready for Anything
The key to dressing for Seattle’s late summer is layering. Think of your outfit like a welcome mat to the city’s changing moods.
-
Bring lightweight tops such as t-shirts or tank tops for sunny afternoons.
-
Pack a couple of long-sleeve shirts or blouses to keep the bugs at bay during evenings outside.
-
A sweater or fleece is non-negotiable for those crisp, cool nights.
-
Don’t forget a light jacket or windbreaker—preferably waterproof—to ward off those occasional sprinkles.
-
Comfortable pants, jeans, or capris are perfect for city explorations as well as light hikes.
-
If you fancy a stroll by the waterfront, toss in a pair of shorts or skirts to enjoy those precious sunny moments.
-
Bring a swimsuit if you’re brave enough for a dip in Lake Washington or have plans to hit a public pool.
Footwear for Days on Your Feet
Seattleites walk a lot, rain or shine. Having the right shoes is critical.
-
Pack a pair of comfortable walking shoes or sneakers suitable for city sidewalks and hiking trails.
-
A pair of water-resistant shoes or boots can save the day if you step into a rain-soaked park or a puddle.
-
If you plan to enjoy the city’s reservoir beaches or waterfront parks, pack sandals or flip-flops for kicking back.
Travel Gear and Accessories
Having the right accessories can elevate your trip from uncomfortable to carefree.
-
A daypack or backpack is crucial for carrying essentials, purchases, and snacks while keeping your hands free to take photos or enjoy the street food.
-
Sunglasses remain a must-have, as the sun can shine bright even when you least expect it.
-
Pack sunscreen and bug spray; both are vital for protecting your skin during outdoor adventures.
-
Don’t bring an umbrella—Seattle locals avoid them since the rain tends to be more misty or windy than drizzly. A waterproof jacket is far better.
-
A baseball cap or a wide-brimmed hat can offer some shade and shield from the light rain.
-
Include a quick-drying towel if you plan on camping or lakeside activities.
-
Travel-sized toiletries and medications can keep you comfortable on the road.
Tech and Documents
Staying connected is part of modern travel.
-
Bring your phone, chargers, and power bank to keep devices running.
-
A camera for capturing Seattle’s iconic sights.
-
Printed or digital copies of your ID, reservation confirmations, and travel insurance.
-
A water bottle to stay hydrated during urban hikes or ferry trips.
