What is the hottest day ever recorded in Fresno?

Fresno's hottest day on record reached 114°F, set on July 11, 2021. That is the single most extreme high in the nearest long-term weather station's full daily record — about 38°F hotter than a typical year's average high of 76°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 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 full 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 Fresno?

The all-time record low in Fresno is 18°F, recorded on January 10, 1949. The gap between that and the 114°F record high — a span of 96°F — is the full range of temperatures Fresno has experienced across its long-term daily record.

Is it normal to be this hot in Fresno?

It depends on how far above Fresno's normal a given day runs. A typical year here averages a daily high near 76°F; the all-time record of 114°F (set 2021) sits about 38°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 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 full 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 5.0°F warmer since 1948 (+0.65°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 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 September 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). 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 114°F record is the rare event the record marks.
