The year, day by day
The year in New Iberia Acadiana runs from a mild 43°F around January 14 to 94°F at the peak near August 8, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 11 through September 15, covering 97 dates. The broader mild season, normal highs of 70°F or more, runs February 27 to November 23.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 43°F around January 14.
The widest day
October 25 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where New Iberia Acadiana Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 97 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
New Iberia Acadiana earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Data-derived climate profile
How New Iberia Acadiana's climate pattern fits together
cooling led · mid swing
Air-conditioning demand is the clearest thermal signal here. New Iberia Acadiana accumulates 3,086 cooling degree days, more than twice its 1,285 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
A moisture-range label is withheld because New Iberia Acadiana's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
August and January mark the typical warm and cold ends of the calendar in New Iberia Acadiana's middle-range seasonal profile. The measured spread is 30.6°F. The annual average is 70°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
The frost-free window extends for about 304 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from New Iberia Acadiana's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For New Iberia Acadiana that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from New Iberia Acadiana's primary station: NEW IBERIA ACADIANA AP (USC00166657). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for New Iberia Acadiana; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for New Iberia Acadiana comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
