What is the hottest day ever recorded in New Orleans?

New Orleans's hottest day on record reached 104°F, set on June 24, 2009. That is the single most extreme high in the nearest long-term weather station's full daily record — about 23°F hotter than a typical year's average high of 81°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 New Orleans?

The all-time record high in New Orleans is 104°F, recorded on June 24, 2009. 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 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 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 New Orleans?

The all-time record low in New Orleans is 6°F, recorded on February 13, 1899. The gap between that and the 104°F record high — a span of 98°F — is the full range of temperatures New Orleans has experienced across its long-term daily record.

Is it normal to be this hot in New Orleans?

It depends on how far above New Orleans's normal a given day runs. A typical year here averages a daily high near 81°F; the all-time record of 104°F (set 2009) sits about 23°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 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 full 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 2.9°F warmer since 1893 (+0.22°F per decade, fitted to the complete years of 1893–2025). 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 New Orleans’s weather gets

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 September runs about 90°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.

At the other end, New Orleans has bottomed out at 6°F (1899). 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 104°F record is the rare event the record marks.
