In New Orleans, October and November are usually the easiest months to build a patio or deck. NOAA’s 1991 to 2020 climate normals show October is the driest month of the year at the city’s airport station, with average highs near 81 degrees. Late winter and early spring are the next most workable stretch.
Most homeowners pick a project first and a start date second. In south Louisiana, the calendar deserves more thought than that.
Rain, heat, and storm season all shape how smoothly outdoor construction goes. Choosing the right time of year to build a patio can save days of waiting on wet ground.
Big Easy Outdoor Design plans and builds patios, decks, outdoor kitchens, pergolas, and sunrooms across greater New Orleans. Below, we walk through what the official weather records say about each season, so you can line up your project with the months that tend to cooperate.
Which Months Are Driest in New Orleans?
October is the driest month on record averages, with a normal of 3.70 inches of rain at the New Orleans International Airport station. November follows at 3.87 inches. Those figures come from NOAA’s 1991 to 2020 climate normals, the official 30-year averages for the station.
For comparison, the same normals put June at 7.62 inches, the wettest month of the year. July and August are not far behind, at 6.79 and 6.91 inches. The yearly normal is 63.35 inches, so rain is part of every season here.
Fewer rainy days usually means fewer delays for digging, grading, and pouring. It also means the ground has more time to dry out between storms, which matters in yards that are slow to drain after a heavy rain.
How Do the Seasons Compare for Outdoor Construction?
Fall and early spring offer the mildest mix of rain and heat. Summer brings the most rain and the hottest afternoons, and it overlaps the weeks when the first hurricanes of a season typically form. Winter is workable but cooler and wetter than fall, with January averaging 5.18 inches of rain.
The table below pulls monthly normals from NOAA’s National Centers for Environmental Information for the New Orleans International Airport station. Temperatures are average daily highs.
| Month | Normal Rainfall | Average High |
|---|---|---|
| January | 5.18 in | 62.5°F |
| March | 4.36 in | 72.3°F |
| April | 5.22 in | 78.5°F |
| June | 7.62 in | 90.0°F |
| August | 6.91 in | 91.3°F |
| October | 3.70 in | 80.6°F |
| November | 3.87 in | 71.2°F |
March is a good spring option. Its normal of 4.36 inches is lower than the months on either side of it, and the average high of 72.3 degrees is comfortable for long days of outdoor work.
How Does Hurricane Season Affect Your Start Date?
The Atlantic hurricane season runs from June 1 to November 30, according to the National Hurricane Center. Its climate summary says the first hurricane of a typical season forms in early to mid August, and the first major hurricane forms in late August or early September.
The same summary says an average season, based on 1991 to 2020 records, brings 14 na
