Portland is finally catching its breath on Tuesday, June 16, 2026, after a run of record-breaking heat that sent weekend temperatures into the triple digits. Clear skies and a cool northwest breeze are keeping highs in the low 80s instead of the oven-like conditions the metro just endured. Portland International Airport reported clear conditions and about 59°F early Tuesday morning, and the high this afternoon is expected to top out near 83°F. The break will be brief, though, with another warmup lined up later in the week.
What To Expect Today
Look for sun all day with a high near 83°F, with temperatures slipping a few degrees late this afternoon. North-northwest winds should run 2 to 12 mph, with gusts up to about 21 mph into the evening. Tonight stays mostly clear with a low near 53°F, according to NWS Portland.
Warming Returns Later This Week
By Thursday, the high-pressure axis is expected to slide east, nudging inland highs back into the upper 80s and giving parts of the valley a shot at 90°F or higher. Monday is on track to run even hotter, with interior highs forecast to reach the low 90s. The forecast discussion also notes a Moderate HeatRisk for portions of the interior on Thursday, Friday, Sunday and Monday. That follows a triple-digit heat alert earlier this week. According to NWS Portland.
Where To Cool Off
Multnomah County and local partners have opened additional cooling sites as heat thresholds were met, and more may come online as temperatures climb again. Residents are encouraged to check county resources or call 311 for the latest on locations and hours. Community groups and daytime centers are also ramping up outreach for people without home air conditioning. For details on shelter activations and transit accommodations, see reporting by OPB.
Heat Safety
If you are sensitive to heat, including older adults, infants, people without A/C, and outdoor workers, health officials advise drinking plenty of water, avoiding strenuous activity during the hottest parts of the day, and using cooling centers if needed. And even if the air feels summery, rivers and lakes can still be shockingly cold and may trigger dangerous cold-water shock, so do not assume the water is safe just because the temperature on land has warmed up.
