• Heat in Oregon, July 5 to 13, 202412 deaths · 3 eventsStrong high pressure aloft setup over the West Coast, centered over portions of California. This system was nearly stationary which brought a prolonged stretch of hot temperatures to northwest Oregon and southwest Washington.
• Heat in Oregon, June 28 to 29, 20082 deaths · 2 eventsDuring the first major heat wave of the season and amid record breaking heat, two men lost their lives to injuries, and it was reported by the sheriff's department that weather may have contributed to each death.
• Heat in Oregon, May 22 to 23, 20172 deaths · 2 eventsRidge of high pressure brought a couple days of warm weather. While air temperatures were warm, river and lake temperatures were still cold, leading to two drownings across the area.
• Heat in Oregon, July 16 to 18, 20182 deaths · 2 eventsHigh pressure over the region led to a stretch of hot day July 12 through July 17th. Hot temperatures led people to cool off in local rivers. There were two drownings recorded on July 16 and July 18.
• Heat in Oregon, August 16 to 17, 20202 deaths · 2 eventsHigh pressure over the region led to a stretch of hot days from August 14 through August 17.
• Heat in Oregon, August 11 to 14, 20162 deaths · 1 eventRidge of high pressure lead to hot temperatures across Northwest Oregon.
• Heat in Oregon, August 25 to 26, 20161 death · 8 injured · 2 eventsRidge of high pressure and offshore winds brought temperatures along the North Oregon Coast up into the mid 80s to mid 90s on August 25. Inland, temperatures on August 25-26 reached the upper 90s.
• Heat in Oregon, July 1 to 5, 20151 death · 2 injured · 3 eventsA strong upper ridge over the region resulted in hot weather for the Willamette Valley where temperatures peaked 10 to 15 degrees Fahrenheit above the seasonal normal.
• Heat in Oregon, June 7 to 9, 20151 death · 1 injured · 1 eventAn unseasonably strong upper level ridge of high pressure resulted in hot temperatures early in June where high temperatures were around 20 degrees higher than the seasonal normals.
• Heat in Oregon, August 7 to 8, 20221 death · 4 eventsStrong high pressure expanded into the region bringing a very warm air mass. High temperatures peaked near 100 degrees on the 7th in portions of the Willamette Valley and through the Columbia River Gorge.
• Heat in Oregon, July 26 to 28, 19981 death · 1 eventA three day heat wave brought record high temperatures to western Oregon July 26-28.
• Heat in Oregon, July 20 to 24, 200613 eventsAn unusually strong ridge of high pressure brought several days of record breaking hot and humid weather to NW Oregon. An Excessive Heat Warning was issued the afternoon of July 20th, and persisted through July 24th.
• Heat in Oregon, July 21 to 24, 200612 eventsDaily maximum temperatures between 100 and 113 degrees were observed at lower elevations, with temperatures 90 to 100 degrees at elevations up to 4000 feet. Several people were treated for heat related illness.
• Heat in Oregon, August 17 to 18, 202211 eventsHigh pressure centered over the Desert Southwest expanded over the Pacific Northwest bringing a brief hot spell to the area.
• Heat in Oregon, July 10 to 14, 200210 eventsA record breaking heat wave shattered many daily record high temperatures across the state, with a few locations breaking all-time records.
• Heat in Oregon, July 28 to 31, 20207 eventsAn Upper level ridge built over the region the last week of July resulting in very hot temperatures and may record highs. Temperatures exceeded 105 degrees in many locations.
• Heat in Oregon, June 24 to 26, 20066 eventsA broad upper ridge of unusually high height coupled with a thermally-induced surface trough of low pressure lingered over the Pacific Northwest for several days. This pattern resulted in persistent offshore flow, and therefore many days of record-smashing high temperatures.
• Heat in Oregon, June 11 to 12, 20194 eventsStrong high pressure and a very dry air mass made for hot conditions over southwest Oregon during this interval.
• Heat in Oregon, July 29 to 30, 20214 eventsA strong high pressure aloft brought a brief hot air mass to the region. Oregon Governor issued an Emergency Declaration Due to Forecasted Heat Across the State affecting 23 counties.
• Excessive Heat and Heat in Oregon, July 28 to 30, 20153 eventsA strong upper level ridge resulted in excessively warm temperatures the last week in July where the high temperatures were 15 to 20 degrees Fahrenheit above the seasonal normal.
• Heat in Oregon, July 12 to 17, 20182 eventsStrong high pressure coupled with very dry air brought very hot temperatures to the area during this interval.
• Heat in Oregon, August 1, 20111 eventA dry weak westerly flow aloft under a broad upper level high pressure system combined with a surface thermal trough to bring several days of temperatures in the 90s.
