Portlanders woke up to a crisp, clear start on Saturday, May 9, 2026, with temperatures hovering near 49F at local airports and not a cloud picking a fight with the skyline. Sunshine is locked in for the day, and inland neighborhoods are on track to warm into the upper 70s, topping out around 79F by late afternoon.
Afternoon Sun And Temperatures
Mostly sunny skies will hang over the metro through the afternoon, with the warmest readings well inland while spots closer to the river and coast stay a bit cooler. North-northwest winds will remain light, generally around 2 to 7 mph, so it is shaping up to be an easy day for yard work, park time, and patio seating. Daytime highs should land in the 70s, and some interior locations may sneak into the low 80s, according to the NWS Portland forecast discussion.
Week Ahead: Tuesday Could Be The Hottest
The warm spell does not stop today. Temperatures are expected to climb further into early next week, with Monday forecast to land near 81F and Tuesday looking like the prime candidate for the week’s peak heat. Some forecast guidance points to inland highs reaching the mid 80s on Tuesday, May 12, although forecasters note that confidence is still low in the exact timing and just how hot it gets. There is only a slight chance of light rain late Tuesday night into Wednesday, so most early week outdoor plans should be safe, per the NWS Portland forecast discussion.
Marine And Wind Outlook
On the water, southerly winds will gradually swing around to northerly as the weekend wraps up. Offshore seas are expected to hold in the 5 to 7 foot range through Sunday. Forecasters say those northerly winds could strengthen Monday into Tuesday toward Small Craft Advisory levels, so mariners and regular ferry riders will want to keep an eye on updates. At this point there are no watches, warnings, or advisories posted for the metro area or the nearby coast.
Plan Ahead
Today offers a prime window for outdoor errands, hikes, and park time before the heat really flexes later in the week. If you are planning events or long stretches outside in the coming days, it is worth thinking ahead about simple heat safety: carry water, skip the hardest exertion during the midday hours, and know your options for cooling off. Multnomah County maintains heat safety tips and a list of cooling locations for people who need relief during hot spells; see Multnomah County heat resources.
