August Packing List for Seattle — What to Wear & Bring

Essentials

If you only pack a few things, pack these.

• Lightweight summer tops and T-shirtsEssential

  Seattle's August averages 76°F — the same warmth as July, and the city's most consistently dry and sunny period with only 5 rain days and full outdoor activity across Capitol Hill, Pike Place Market, and Alki Beach.

• Light summer dresses or shortsEssential

  August is Seattle's other peak summer month — light dresses and shorts are appropriate for all daytime outdoor activities including the Pike Place Market, Seattle Center, Green Lake, and Alki Beach.

• Light long-sleeve layerEssential

  Seattle's August evenings at 57°F, particularly on the Elliott Bay waterfront and at Alki Beach in West Seattle, are cooler than the warm afternoons — a light long-sleeve layer extends outdoor evening comfort.

• Comfortable flat-soled walking shoesEssential

  Pike Place Market's cobblestone ramps and Capitol Hill's hillside terrain still benefit from flat-soled shoes even in dry August — smooth-soled footwear is harder to control on cobblestones regardless of rain.

• SunglassesEssential

  Seattle's August sun is strong during the city's driest month — polarized sunglasses reduce Puget Sound water reflection glare during Alki Beach and Elliott Bay waterfront time.

• Sunscreen SPF 30+Essential

  Seattle's August extended daylight hours and only 5 rain days mean significant UV accumulation during outdoor time — SPF 30+ is essential for Alki Beach, the waterfront, and outdoor festival attendance.

• Light packable jacketEssential

  Seattle's August evenings at 57°F near the Elliott Bay waterfront and outdoor concert venues are reliably cooler than the warm afternoons suggest — never attend an evening outdoor event without a light jacket.

• Packable light jacketRecommended

  The Elliott Bay waterfront and Alki Beach in August at 57°F evenings with Puget Sound wind are noticeably cooler than inland Capitol Hill — a packable jacket handles waterfront evening walks and outdoor concert venues.

• One light sweaterRecommended

  Late August in Seattle can produce the first hints of fall — having a slightly heavier sweater available covers the occasional cooler August evening near the waterfront and the late-month temperature dip.

Footwear

• Comfortable flat-soled walking shoesEssential

  Pike Place Market's cobblestone ramps and Capitol Hill's hillside terrain still benefit from flat-soled shoes even in dry August — smooth-soled footwear is harder to control on cobblestones regardless of rain.

• SandalsRecommended

  Seattle's August 76°F afternoons are the city's best for sandals — Alki Beach, the waterfront, and Capitol Hill outdoor patios are all comfortable for open footwear during the dry summer peak.

• Comfortable sneakersRecommended

  Seattle's August neighborhood festivals, Burke-Gilman Trail, and Green Lake loop all reward supportive sneakers for the active summer outdoor days.

Accessories

• SunglassesEssential

  Seattle's August sun is strong during the city's driest month — polarized sunglasses reduce Puget Sound water reflection glare during Alki Beach and Elliott Bay waterfront time.

• Sunscreen SPF 30+Essential

• Reusable water bottleRecommended

  Seattle's August active outdoor days — Seafair, neighborhood block parties, Alki Beach, and the Burke-Gilman Trail — require consistent hydration during the warm sunny days.
