New Orleans, LA: average weather by month
NOAA 1991–2020 climate normals at the NEW ORLEANS AP station, read through NOAA's Regional Climate Centers' ACIS service. Every column below is the station's own average for that month over that 30-year period — not a forecast. The rainfall figures are NOAA's precipitation normal, so they count rain plus melted snow (and any other frozen precipitation, as water), not rain alone.

Reading the twelve months
By these station averages, July runs the warmest (91.4°F average high) and January the coolest (62.5°F average high). June averages the most rain (7.62 in) and October the least (3.7 in).
Months within our comfort range
We set one fixed, objective threshold ourselves — average high between 65°F and 80°F, and average rainfall under 2 in — and check each of the twelve rows against it. This is not a claim that any other month is bad, and not our judgment of which month suits any trip; it is just which rows on the table above clear the stated numbers. See how we set this threshold.
No month at New Orleans clears both parts of the threshold at once by this station's normals — most months here run either warmer, cooler, or wetter than the range we set.

About the station
These normals are read at a single NOAA/NWS station, NEW ORLEANS AP (station ID 12916), not averaged across the whole metro area. A different station nearby — higher ground, closer to water, further inland — can read noticeably different numbers, especially for rain. Run this station's ACIS query yourself.
What this page adds
A search for "new orleans weather by month" mostly returns a day-by-day forecast calendar (useful only for the next two weeks) or a local weather office page built for a different question. This page puts all twelve months of the 1991–2020 average on one screen, in both °F/°C and inches/mm, names the exact station behind the numbers, and sets it next to a few nearby cities so the difference is visible at a glance.
