What is the hottest day ever recorded in Portland?

What is the record high temperature in Portland?

The all-time record high in Portland is 116°F, recorded on June 28, 2021. Records are drawn from the nearest long-term weather station's full daily history, so this is the hottest single day the station has ever logged — not a typical summer peak.

What is the coldest day ever recorded in Portland?

Portland's coldest day on record bottomed out at -3°F, set on February 2, 1950. Like the record high, it comes from the station's complete daily record, so it captures the most extreme cold the area has recorded rather than an average winter low.

What is the record low temperature in Portland?

Is it normal to be this hot in Portland?

It depends on how far above Portland's normal a given day runs. A typical year here averages a daily high near 64°F; the all-time record of 116°F (set 2021) sits about 52°F above that. The anomaly readout at the top of this page compares the current temperature against this month's normal high, so you can see exactly how unusual today is rather than guessing.

When did Portland set its temperature records?

Portland's record high of 116°F was set in 2021 (June 28, 2021), and its record low of -3°F in 1950 (February 2, 1950). Both are pulled from the station's complete daily record going back to 1938, so they reflect the true extremes rather than a recent or partial sample.

Has Portland been getting hotter?

Yes — Portland's annual mean temperature has trended about 2.4°F warmer since 1938, in line with the long-term warming seen across nearly every US city. That gradual shift in the average is separate from the all-time records above, which mark the single most extreme days rather than the trend, but a warming baseline is part of why recent years more often brush up against the record-high end.

How extreme Portland’s weather gets

Portland’s weather is usually mild by its own standards — a typical year averages a daily high near 64°F, and the normal high for June runs about 74°F. The records sit well outside that everyday range. The hottest day on record reached 116°F in 2021 — roughly 52°F above a typical year’s average high, the kind of gap that turns an ordinary summer into a genuine heat event.

At the other end, Portland has bottomed out at -3°F (1950). Together the two extremes span 119°F — the full width of what this place’s weather has done across the station’s daily record back to 1938. Those edges are exactly why the anomaly readout at the top of this page is worth a glance: it shows where today falls between the normal and the record, so a hot afternoon can be judged against the real history rather than a hunch. A reading a few degrees over the June normal is ordinary; one pushing toward the 116°F record is the rare event the record marks.
