At 5:35 a.m. Wednesday, June 10, 2026, Portland is waking up mostly cloudy and cool, sitting at about 54°F at Portland International Airport with a light southwest breeze. Clouds are expected to thin through the morning, setting up a mild, partly sunny afternoon before the real heat kicks in later this week.
Today will be partly sunny with a high near 69°F and light west winds, with overnight lows around 49°F. From there, the thermostat heads steadily upward, with highs climbing into the upper 70s by Thursday and Friday.
Weekend Heat Watch
An Extreme Heat Watch, issued Tuesday, will be in effect from Sunday morning through Monday evening for the Portland metro area and parts of the Columbia River Gorge, with the hottest conditions expected Sunday and Monday. Highs are forecast to push into the 90s, peaking near the upper 90s on Monday, and overnight lows in the low to mid 60s will offer only limited relief. According to NWS Portland, this could be the warmest stretch of 2026 so far.
Cooling Resources And Safety
Local officials are urging residents without air conditioning to plan ahead and line up cooling options now. Call 211 to find nearby cool spaces and transportation assistance, and see Multnomah County for county guidance on cooling centers and heat safety.
What To Expect And How To Prepare
Expect mostly dry conditions through Friday, a jump into the mid to upper 80s on Saturday, then widespread 90s on Sunday and Monday. The combination of dry air and afternoon breezes also raises fire weather concerns over the weekend. If you have outdoor plans, try to shift strenuous activity to the morning hours, drink plenty of water, and check on elderly neighbors.
