Is it normal to be this hot in Salt Lake City?

It depends on how far above Salt Lake City's normal a given day runs. A typical year here averages a daily high near 65°F; the all-time record of 107°F (set 1960) sits about 42°F above that. When a live reading is available, the live readout just below the record high and low compares it with the temperature typical for that hour this month (estimated from the month's normal high and low), so you can see how unusual the day is rather than guessing.

When did Salt Lake City set its temperature records?

Salt Lake City's record high of 107°F was set in 1960 (July 26, 1960), and its record low of -22°F in 1949 (January 25, 1949). Both are pulled from the station's full daily record going back to 1948, so they reflect the true extremes rather than a recent or partial sample.

Has Salt Lake City been getting hotter?

Yes — Salt Lake City's annual mean temperature has trended about 4.9°F warmer since 1948 (+0.64°F per decade, fitted to the complete years of 1948–2025). 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 Salt Lake City’s weather gets

Salt Lake City’s weather is usually mild by its own standards — a typical year averages a daily high near 65°F, and the normal high for September runs about 81°F. The records sit well outside that everyday range. The hottest day on record reached 107°F in 1960 — roughly 42°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, Salt Lake City has bottomed out at -22°F (1949). Those edges are why the today-versus-normal readout above 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 September normal is ordinary; one pushing toward the 107°F record is the rare event the record marks.
