What is each month like in Metairie?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

What do the station records around Metairie say?
Each row is a NOAA station's own 1991-2020 normals, with the snow and frost dates the grid does not give. A record downhill or nearer the coast than the city can run warmer, one uphill cooler: compare the elevations.

How much snow, how late a frost, what zone and how much sun in Metairie?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, New Orleans (4 miles W, 4 ft). It gets 0 inches of snow in a normal year. The last spring frost (32°F) comes after January 30 in half of years and the first autumn frost before December 31. Its record high is 105°F (2023) and its record low 11°F (1989), on the National Weather Service's long record for the area (kept since 1946).
The USDA's 2023 Plant Hardiness Zone Map puts Metairie in zone 9b across its 5 ZIP code areas.
Over a year 79% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (4.7 kWh per square metre a day, NASA POWER 2001-2020); October is the sunniest month (85%) and February the cloudiest (73%).
New Orleans's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Metairie; the nearest record's month pages have them.
