What is the coldest day ever recorded in New Orleans?

New Orleans's coldest day on record bottomed out at 6°F, set on February 13, 1899. 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.

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 New Orleans set its temperature records?

New Orleans's record high of 104°F was set in 2009 (June 24, 2009), and its record low of 6°F in 1899 (February 13, 1899). Both are pulled from the station's complete daily record going back to 1893, so they reflect the true extremes rather than a recent or partial sample.

Has New Orleans been getting hotter?

Yes — New Orleans's annual mean temperature has trended about 2.4°F warmer since 1893, 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.

New Orleans’s weather is usually mild by its own standards — a typical year averages a daily high near 81°F, and the normal high for June runs about 93°F. The records sit well outside that everyday range. The hottest day on record reached 104°F in 2009 — roughly 23°F above a typical year’s average high, the kind of gap that turns an ordinary summer into a genuine heat event.

Together the two extremes span 98°F — the full width of what this place’s weather has done across the station’s daily record back to 1893. 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 104°F record is the rare event the record marks.
