What is the hottest day ever recorded in Phoenix?

Phoenix's hottest day on record reached 122°F, set on June 26, 1990. That is the single most extreme high in the nearest long-term weather station's full daily record — about 35°F hotter than a typical year's average high of 87°F, which is why a day like it stands out as genuinely rare rather than just a hot afternoon.

What is the record high temperature in Phoenix?

The all-time record high in Phoenix is 122°F, recorded on June 26, 1990. 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 Phoenix?

Phoenix's coldest day on record bottomed out at 17°F, set on January 5, 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 Phoenix?

The all-time record low in Phoenix is 17°F, recorded on January 5, 1950. The gap between that and the 122°F record high — a span of 105°F — is the full range of temperatures Phoenix has experienced across its long-term daily record.

Is it normal to be this hot in Phoenix?

It depends on how far above Phoenix's normal a given day runs. A typical year here averages a daily high near 87°F; the all-time record of 122°F (set 1990) sits about 35°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 Phoenix set its temperature records?

Phoenix's record high of 122°F was set in 1990 (June 26, 1990), and its record low of 17°F in 1950 (January 5, 1950). Both are pulled from the station's complete daily record going back to 1933, so they reflect the true extremes rather than a recent or partial sample.

Has Phoenix been getting hotter?

Yes — Phoenix's annual mean temperature has trended about 10.3°F warmer since 1933, 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 Phoenix’s weather gets

Phoenix’s weather is usually mild by its own standards — a typical year averages a daily high near 87°F, and the normal high for June runs about 104°F. The records sit well outside that everyday range. The hottest day on record reached 122°F in 1990 — roughly 35°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, Phoenix has bottomed out at 17°F (1950). Together the two extremes span 105°F — the full width of what this place’s weather has done across the station’s daily record back to 1933. 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 122°F record is the rare event the record marks.
