Portland in July is peak Pacific Northwest summer. NOAA Portland (PDX) data put afternoon highs at 27°C / 81°F and overnight lows at 14°C / 57°F with 4 rain days — the driest local month. Heat-dome events (the 2021 Pacific Northwest heat dome reached 47°C / 116°F at PDX, an all-time record) make 35°C / 95°F+ stretches possible; pack accordingly. The dressing rule lightens: lightweight cotton, mid-weight cardigan for cool mornings and AC, denim or chinos, leather sneakers or Danner boots, packable rain shell, sunglasses, sun hat. The Waterfront Blues Festival historically runs early July at Tom McCall Waterfront Park; Independence Day fireworks on July 4. Pendleton, Filson, Danner, Nike, Adidas, Tellason, Imogene + Willie, Wildfang remain the local register. Stumptown Coffee, Heart, Coava continue as the third-wave coffee anchors. Forest Park, Mt Hood, Multnomah Falls, Cannon Beach (90 minutes west — chilly Pacific year-round), Hood River (Columbia Gorge windsurfing) all reward the lightweight-cotton-layered approach.
Portland July is peak summer — Waterfront Blues Festival lighting up Tom McCall Waterfront Park for four days, the post-9pm light still good at 9:30, the cardigan-as-AC-layer at the Stumptown Annex still pulled on every time you cross a threshold.
