A record-breaking heat wave swept across Western Washington on June 15-16, 2026, pushing temperatures well above the 95-degree threshold at multiple locations. In the greater Vancouver, Washington area — the southern edge of Western WA — readings briefly touched 100 degrees on the afternoon of Monday, June 16. Olympia recorded 93 degrees officially, breaking its previous daily record of 88 degrees, while informal readings in parts of the city reached 97. The Chehalis-Centralia corridor in southwest Washington saw upper-90s by Monday afternoon, and similar readings were recorded at other inland Western WA stations.
The event was driven by an anomalous ridge of high pressure building over the Pacific Northwest, producing temperatures 20 to 23 degrees above the seasonal norm for mid-June. The National Weather Service issued the region's first heat advisory of 2026, covering King, Pierce, Snohomish, and Thurston counties as well as portions of southwest Washington, running through early Tuesday morning.
The timing coincided with the FIFA World Cup match between the United States and Portugal hosted at Seattle Stadium on Monday, June 16, drawing large outdoor crowds during peak afternoon heat. Local governments and nonprofits opened cooling centers across the region. The heat wave dissipated by Wednesday as onshore marine air returned. The Predict Six community was closely divided, with 52 percent correctly forecasting that Western WA would hit 95 degrees or higher.
