Portland woke up to clear skies and cool mid 50s on Sunday, July 5, 2026, but the mild start is not sticking around for long. Highs are expected to climb to around 84°F this afternoon, with an even stronger warm up lined up for Monday, July 6.
Afternoon Heat And Wind
Mostly sunny skies will bump afternoon highs into the low to mid 80s today, with north northwest winds around 5 to 9 mph and gusts up to about 18 mph. Monday is on track to be the hottest day in the short term forecast, with inland spots pushing into the upper 80s and a few neighborhoods potentially flirting with 90°F. That brings a localized Moderate HeatRisk for inner Portland and parts of the Gorge, so if you are outside for long stretches, keep the water handy, grab shade breaks, and keep outdoor chores shorter, according to NWS Portland.
Water Safety And Cooling Resources
Even when the air feels summery, local rivers and lakes stay very cold and can trigger cold water shock, and currents can still be swift. Wear a life jacket, stay honest about your swimming ability, and do not head out alone. For anyone who is heat sensitive or without air conditioning, the county and city open cooling spaces during multi day heat events and track other relief options. Check local listings or call 211 before you go; see Multnomah County for current locations and guidance.
Coastal And Marine Conditions
Onshore northerly winds will be strongest along the coast and through the Columbia River Gorge, with seas building to around 6 to 8 feet and offshore gusts near 30 knots. Small Craft Advisories stay in effect through about 2 a.m. PDT Monday, July 6, so boaters should expect choppy conditions and plan accordingly. Check the marine forecast before leaving the dock and secure any lightweight gear this evening, according to NWS Portland.
Legal Notes
A burn ban remains in place across parts of the metro area, which means open burning and some outdoor fires are restricted while conditions stay dry. Skip the fireworks and backyard burn piles for now, and review local rules before lighting anything; see Multnomah County for details.
