What to Wear in Seattle in July 2026
Seattle in July: 25°C afternoons, 14°C mornings, just 5 rain days, 312 sunshine hours — the driest, sunniest month.
- Linen midi dresses and cotton shorts — July finally rewards summer
- Birkenstocks as primary footwear (peak month)
- Tank + linen shirt combos for Kerry Park breeze and AC restaurants
- A swimsuit + cover-up for Alki Beach or Lake Union paddleboards
- A cardigan in the bag — Puget Sound evenings drop to 14°C
- SPF 30 reapplied twice — latitude plus water reflection is stronger than locals admit
- Leave the cardigan behind — Kerry Park sunset photos get cold
- Stilettos on Seattle hills — tech-casual city has no need for them
- Underestimate UV — latitude plus water reflection surprises visitors
July is Seattle's best-kept secret: driest, sunniest, warmest. NOAA climate data show afternoons at 25°C (77°F), mornings at 14°C (57°F), only 5 rain days and 15mm of rainfall — less than Lisbon. And 312 sunshine hours, the most of any month. Locals emerge from months of gray and commit to outdoor activity: Alki Beach, Discovery Park, Olympic National Park day trips, Lake Union paddleboards, rooftop bars. The July Seattle uniform finally lets go of the rain shell (mostly) and leans into sundresses, shorts, linen, Birkenstocks. But mornings still start at 14°C with Puget Sound breeze; bring a cardigan for waterfront walks, Pike Place Market mornings, and Kerry Park sunsets. Tech culture continues to dominate — so dress codes remain smart-casual most places, and REI Flagship Store is a genuine tourist stop.

The capsule
01Light linen midi dress or sundressFinally appropriate for Seattle. Short, midi, or maxi — all work. Bright colors read local intent.
02Tank + linen shirt comboTank for warm afternoons (25°C+); linen shirt open over it for Kerry Park breezy sunsets and AC restaurants.
03Tailored cotton shorts + linen trousersShorts for beach and park days; linen trousers for Capitol Hill dinners and more polished restaurants.
04Thin cardigan or light denim jacketStill needed. Puget Sound morning and evening breeze is cool even in July. Roll into backpack daily.
05Birkenstocks + clean sneakersBirkenstocks become primary in July. Sneakers for long walking days (Discovery Park 5 miles is real).
06Commuter backpack or straw toteBackpack for urban days. Straw tote for Alki Beach days (tech-casual city allows beach energy).
- Swimsuit + cover-up (Alki Beach, Lake Union) — Seattle has legitimate swim culture in July — Alki Beach, Lake Washington, Lake Union kayaking. Simple swimsuit + cover-up works.
- Sunglasses + baseball cap + SPF 30 — Seattle July UV is higher than visitors expect due to latitude and elevation. Baseball cap + oversized sunglasses + SPF 30 (reapplied twice a day).
Day to night
Tank · cotton shorts · Birkenstocks · straw tote · baseball cap. Pike Place, then ferry to Bainbridge Island.
Linen midi dress · denim jacket · Sambas · small crossbody. Dinner at The Walrus and the Carpenter, drinks at Bathtub Gin.
What to avoid
- Heavy rain gear — July is the one month you can truly pack light
- Assuming California summer heat — Seattle July averages 25°C, not 35°C
- Underestimating UV — latitude plus water reflection is stronger than locals admit
- Stilettos — Seattle hills are real and tech-casual has no use for them
Frequently asked questions
Per NOAA climate data: average daily high is 25°C (77°F), low is 14°C (57°F). Only 5 rain days (the driest month of the year) with just 15mm rainfall. 312 sunshine hours — the most of any Seattle month. Mornings stay cool around 14°C with Puget Sound breeze; afternoons warm to 25°C+ on sunny days.
The best month. Driest, sunniest, and longest remaining daylight. The trade-off: peak tourism, higher prices, and crowds at major attractions (Space Needle, Pike Place, Kerry Park). Book hotels and restaurants 3+ months out for July weekends.
Technically useful but often skippable. Only 5 rain days per month and 15mm total — less than Paris, London, or Lisbon. If you're visiting for 3-4 days, you can reasonably skip the rain shell and rely on a cardigan or denim jacket. If staying longer, pack one for the 1-2 rainy afternoons.
Smart casual layered. Sundress or nice jeans + blouse + cardigan. The observation deck is outdoor-exposed at 520 feet — 5-10°C cooler than ground level, with real wind. Closed-toe shoes (the walkway is open). Skip stilettos — floor is metal grating in spots.
Down to 14°C (57°F) by midnight on most nights, and Puget Sound-side neighborhoods (Alki, Ballard waterfront) can feel 3-5°C cooler due to water breeze. A cardigan, denim jacket, or light sweater is reliably useful after 8pm. Kerry Park sunset photos (popular Instagram spot) get legitimately cold by the time you shoot them.
