Portland starts Monday under cloudy skies and around 61 degrees, but the gray cover will not last. The city is headed for a mostly sunny afternoon with a high near 84 and light north-northwest winds around 5 mph.
The morning-to-afternoon flip is the main story, with temperatures climbing through the 60s before reaching the mid-70s around midday and the low 80s later in the day. No rain is expected Monday, and no watches, warnings or advisories are posted for the area.
Tonight will be mostly clear with a low near 59, according to the National Weather Service Portland office. A light north-northwest breeze should ease into a quiet evening, making for comfortable conditions after sunset.
Warm Through Thursday, Then A Cooler Turn
Tuesday looks nearly identical, with mostly sunny skies and a high near 84 after an overnight low around 58. Wednesday trims the afternoon high to about 81 under partly sunny skies, before Thursday briefly rebounds to around 85.
Thursday morning could bring patchy fog before 7 a.m., followed by mostly sunny skies. Friday remains mostly sunny and near 82, while Saturday cools to around 77 and Sunday lands near 79.
Small Shower Chances Arrive This Weekend
Rain stays essentially off the table through midweek, with precipitation chances at or near zero. Chances tick up slightly Friday through Sunday, topping out around 7% in the forecast, so most Portland plans should stay dry even as the weekend turns cooler.
For now, the practical forecast is simple: expect a light layer for the cloudy morning, then plan for sun and summer warmth by afternoon. Winds remain generally light in the city, though breezier conditions are more likely in exposed areas and along the Columbia River Gorge.
