What is the record high temperature in Fresno?

The all-time record high in Fresno is 114°F, recorded on July 11, 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 Fresno?

Fresno's coldest day on record bottomed out at 18°F, set on January 10, 1949. 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.

Is it normal to be this hot in Fresno?

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 Fresno set its temperature records?

Fresno's record high of 114°F was set in 2021 (July 11, 2021), and its record low of 18°F in 1949 (January 10, 1949). Both are pulled from the station's complete daily record going back to 1948, so they reflect the true extremes rather than a recent or partial sample.

Has Fresno been getting hotter?

Yes — Fresno's annual mean temperature has trended about 4.8°F warmer since 1948, 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 Fresno’s weather gets

Fresno’s weather is usually mild by its own standards — a typical year averages a daily high near 76°F, and the normal high for June runs about 91°F. The records sit well outside that everyday range. The hottest day on record reached 114°F in 2021 — roughly 38°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, Fresno has bottomed out at 18°F (1949). Together the two extremes span 96°F — the full width of what this place’s weather has done across the station’s daily record back to 1948. 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 114°F record is the rare event the record marks.
