The year, day by day
The year in Morgan City runs from a mild 45°F around January 12 to 91°F at the peak near July 26, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 29 through August 26, covering 59 dates. The broader mild season, normal highs of 70°F or more, runs March 7 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 45°F around January 12.
Where the wet dates fall
The likeliest wet date is August 13, when 48% of years recorded at least a hundredth of an inch. The driest is October 21 at 21%. Summed across the calendar, that is about 113 wet dates a year.
The widest day
November 13 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Where Morgan City Stands Nationally
This is one of the wettest normals climates ranked: about 59 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 19°F.
Morgan City earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Morgan City runs a summer-peaked wet season
35% of Morgan City's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is August at 7.3", on an unusually narrow 29.2°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: August, June, July, taking 35% of the annual total between them.
- Driest month: February at 3.3".
- Winter share: 21% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Morgan City, it arrives in quantity
58.5" of precipitation falls across only about 113 wet days here, averaging 0.52 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 113 a year, 31% of all days
- Average depth per wet day
- 0.52 inches
- Most wet days
- August, about 15
- Fewest wet days
- October, about 7
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Morgan City's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Morgan City's climate pattern fits together
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Morgan City. Cooling totals 3,064 degree days, more than double the 1,172 heating measure, and the 29.2°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 58.5 inches of precipitation at Morgan City. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Morgan City's 29.2°F seasonal spread is compact even though precipitation is abundant. July and January mark the typical warm and cold ends of the calendar. The annual average is 70°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
A frost-free growing-season length is not available for Morgan City. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Morgan City'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 Morgan City that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
