How extreme Baton Rouge’s weather gets

Baton Rouge’s weather is usually mild by its own standards — a typical year averages a daily high near 79°F, and the normal high for September runs about 89°F. The records sit well outside that everyday range. The hottest day on record reached 106°F in 2023 — roughly 27°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, Baton Rouge has bottomed out at 7°F (2025). 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 106°F record is the rare event the record marks.

Frequently asked

What is the hottest day ever recorded in Baton Rouge?
Baton Rouge's hottest day on record reached 106°F, set on August 24, 2023. That is the single most extreme high in the nearest long-term weather station's full daily record — about 27°F hotter than a typical year's average high of 79°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 Baton Rouge?
The all-time record high in Baton Rouge is 106°F, recorded on August 24, 2023. 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 Baton Rouge?
Baton Rouge's coldest day on record bottomed out at 7°F, set on January 22, 2025. 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 Baton Rouge?
The all-time record low in Baton Rouge is 7°F, recorded on January 22, 2025. The gap between that and the 106°F record high — a span of 99°F — is the full range of temperatures Baton Rouge has experienced across its long-term daily record.
Is it normal to be this hot in Baton Rouge?
It depends on how far above Baton Rouge's normal a given day runs. A typical year here averages a daily high near 79°F; the all-time record of 106°F (set 2023) sits about 27°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 Baton Rouge set its temperature records?
Baton Rouge's record high of 106°F was set in 2023 (August 24, 2023), and its record low of 7°F in 2025 (January 22, 2025). Both are pulled from the station's full daily record going back to 1930, so they reflect the true extremes rather than a recent or partial sample.
Has Baton Rouge been getting hotter?
Yes — Baton Rouge's annual mean temperature has trended about 1.5°F warmer since 1931 (+0.16°F per decade, fitted to the complete years of 1931–2024). 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.
