Kenner sits right where the Mississippi River meets Lake Pontchartrain, just minutes from the French Quarter and serving as the front door to greater New Orleans through Louis Armstrong International Airport. This is a city shaped by Cajun and Creole food traditions, where neighborhood joints serve po'boys, gumbo, fried alligator, and boiled crawfish alongside cold beers. Kenner's own Rivertown historic district lines the Mississippi levee with museums, a planetarium, performance theaters, and the story of La Salle's 1682 landing, while the wider New Orleans metro delivers a year-round calendar of world-class music, parades, and cultural festivals that few cities on earth can match.
Your ideal window falls in two stretches: mid-February through early May, and early October through late December, except for a stretch in early March and another around late November when conditions can dip. Spring edges ahead as the top pick thanks to mild highs of 80.5°F (26.9°C) and the concentration of signature events: the French Quarter Festival fills mid-April with free live music across the historic Quarter, and Jazz Fest takes over the Fair Grounds Race Course in late April and early May with hundreds of artists and legendary food vendors. Fall is a strong runner-up, when October's dry, comfortable weather and peak visitor energy coincide with lower humidity and the New Orleans Film Festival. If you'd rather avoid the biggest crowds and highest prices, the October through December window delivers pleasant temperatures and thinner tourist volume outside of the Thanksgiving holiday week.
Spring in Kenner - Louis Armstrong International Airport, LA, US
Spring is when the New Orleans area hits its stride. The French Quarter Festival, the largest free music festival in the South, fills mid-April with performances on more than 20 stages throughout the historic Quarter alongside food from dozens of Louisiana restaurants. A couple of weeks later, Jazz Fest takes over the Fair Grounds Race Course for two weekends spanning late April into early May, drawing hundreds of thousands of visitors for a mix of national headliners and homegrown talent across jazz, blues, zydeco, gospel, and Cajun genres. The food at Jazz Fest is legendary in its own right: crawfish beignets, Crawfish Monica, cochon de lait po'boys, and Mango Freeze are as much a reason to attend as the music.
Afternoons warm to seasonal highs of 80.5°F (26.9°C), comfortable enough for a full day outdoors without the punishing humidity that arrives later. Mornings start around 60.2°F (15.7°C), so layers work well for early strolls along the Rivertown levee or a swamp kayak tour through the wetlands west of town. Showers pop up sporadically, with roughly one to four wet days per month, and March is one of the drier stretches at just 18% rain chance. This is the busiest tourist season, and hotel rates reflect the demand, so book well in advance if your trip overlaps with Jazz Fest or French Quarter Fest.
Long spring evenings help too: by May, the sun doesn't set until close to 7:45 PM, giving you extra hours to explore Kenner's Laketown waterfront or catch a volleyball tournament at Coconut Beach Sand Sports Complex on the shores of Lake Pontchartrain. Crawfish season peaks in spring, so make a point of ordering a boiled crawfish platter at one of Kenner's no-frills seafood spots along Williams Boulevard.
Summer in Kenner - Louis Armstrong International Airport, LA, US
Summer in the New Orleans area is not for the faint of heart. The ESSENCE Festival of Culture arrives in early July, a massive celebration of Black culture, music, and community at the Caesars Superdome, and Satchmo SummerFest honors Louis Armstrong's legacy with performances and brass band parades later in the summer. These events draw dedicated crowds willing to brave the heat, and hotel rates actually dip below average since casual tourists tend to stay away. If you time it right, you'll find discounted accommodations and shorter lines at most attractions.
Seasonal highs average 92.2°F (33.4°C) with lows that barely cool to 75°F (23.9°C) overnight, creating a relentless blanket of warmth and humidity. Early to mid-August brings the peak: highs push to 94°F (34.4°C) with overnight lows of 77.1°F (25.1°C). This is also the wettest stretch of the year, with two to five significant rain days per month and afternoon thunderstorms that roll in fast and dump heavy downpours before clearing out. July sees the highest frequency at 31% rain chance.
Plan outdoor activities for mornings and spend the hottest afternoon hours in air-conditioned spots like the Kenner Planetarium and MegaDome Cinema in Rivertown, where the 50-foot dome screen offers astronomy shows and immersive films. Pack lightweight, breathable clothing, a hat, and plenty of sunscreen. If you do venture to the waterfront, Laketown's breezes off Lake Pontchartrain offer modest relief from the thick air.
Fall in Kenner - Louis Armstrong International Airport, LA, US
October is the single busiest month for visitors to the area, and for good reason. Humidity drops noticeably, rain becomes infrequent at just 15% chance in October, and the whole region takes on a renewed energy after the summer swelter fades. The New Orleans Film Festival typically screens in the fall, drawing filmmakers and film lovers to venues around the city. In November, the Oak Street Po-Boy Festival celebrates one of the region's most iconic sandwiches, while sports fans pack the Caesars Superdome for the Bayou Classic rivalry game around Thanksgiving weekend.
Seasonal highs average a comfortable 81.6°F (27.6°C) and lows settle to 62.1°F (16.7°C), making it feel like ideal outdoor weather for swamp tours, bike rides along the lakefront, or an afternoon wandering Heritage Park's replica village in Rivertown. November is one of the driest months at just 14% rain chance, so you can plan outdoor days with confidence. Accommodation prices run slightly higher than average given the tourist volume, especially around October weekends.
By late November, the holiday season begins to take shape, and you'll start seeing festive decorations appear across the city. Daylight shortens to about 10.6 hours by November, so factor earlier sunsets into your sightseeing schedule. A light jacket is smart for evening outings, but you won't need heavy layers until winter properly arrives. The Treasure Chest Casino in Kenner's Laketown is a reliable evening option when the sun goes down early.
Winter in Kenner - Louis Armstrong International Airport, LA, US
Winter in the Kenner and New Orleans area revolves around two massive draws: the holiday season and Mardi Gras. Carnival season officially kicks off in early January and builds through weeks of parades, king cake, and krewe celebrations before culminating on Fat Tuesday, which falls in February or early March depending on the year. Super-krewes like Endymion and Bacchus roll through the streets with celebrity riders, massive floats, and marching bands, and the entire metro becomes one extended celebration. If Mardi Gras is your goal, plan to arrive at least a few days before Fat Tuesday to catch the buildup.
Highs average 67.1°F (19.5°C) and lows dip to 45.7°F (7.6°C), a refreshing change from the summer sauna. You'll want a medium-weight jacket for mornings and evenings, but afternoons can feel surprisingly mild under the Louisiana sun. Precipitation lands in the range of one to three significant rain days per month, with December seeing a 23% chance while January drops to 20%. Snow is essentially nonexistent. Days are short at around 10.2 hours of daylight in December, so plan your outdoor sightseeing accordingly.
Outside of Carnival season, winter is one of the quieter periods for tourism, meaning shorter waits at restaurants and more availability at Kenner's hotels near the airport. The Sugar Bowl college football game draws fans over the New Year's holiday, and the holiday season itself brings festive programming and special events around the French Quarter. Pack layers rather than heavy winter gear: a sweater, a rain-resistant jacket, and comfortable walking shoes will cover most winter days here.

Travel Tips & Safety for Kenner - Louis Armstrong International Airport, LA, US
Kenner sits right next to Louis Armstrong New Orleans International Airport, making it one of the most convenient home bases for exploring the metro area. A rental car is the easiest way to get around Kenner itself and to reach swamp tour launch points west along I-10, though the Regional Transit Authority operates bus service into downtown New Orleans. Rideshare services are widely available and work well for trips to the French Quarter, which is about 15 miles east.
Hurricane season runs from June through November, with the highest risk in August and September. Keep an eye on forecasts if you're visiting during these months and have flexible travel plans in case of tropical weather. The heat index in summer can push well beyond the air temperature, so stay hydrated and take breaks in shade or air conditioning during midday hours.
In the New Orleans metro, watch for pickpockets in crowded festival and parade settings, and keep valuables secured when navigating packed events like Mardi Gras or Jazz Fest. Stick to well-lit, populated streets at night, particularly in less familiar neighborhoods outside the main tourist corridors.
