What Is the Best Time of Year to Go On a Mississippi River Cruise?
Written by Blue Water Holidays - Friday 8th August 2025
There's something utterly magical about cruising America's greatest river. Picture yourself on the deck of a traditional paddlewheeler, watching the sun dip below cypress trees while jazz music drifts across the water from some distant shore.
The Mississippi isn't just a waterway. It's a living piece of American history, stretching over 2,340 miles from Minnesota's pristine lakes all the way down to Louisiana's vibrant delta.
But here's the thing about cruising this mighty river: timing really is everything. The weather swings dramatically as you travel from north to south, and choosing the right season for you is crucial to ensure a comfortable, enchanting journey on a paddle steamer.
Whether you're dreaming of exploring historic antebellum mansions, discovering the birthplace of the blues, or simply watching bald eagles soar overhead, the when matters just as much as the where. Here’s our guide to the best time of year for a Mississippi River cruise so that you can feel confident in when to book your trip.
What is the Best Time of Year to Go on a Mississippi River Cruise?
The best time to cruise the Mississippi River is during the months of spring (March, April, May) or fall (September, October, November) to avoid the extreme hot and cold temperatures in summer and winter. These shoulder seasons offer that sweet spot where you're not battling extreme temperatures, the scenery is at its most spectacular, and you'll find the best balance of comfortable weather and reasonable crowds.
Bear in mind that the specific timing for Mississippi River cruising depends on which section of the river you're planning to explore. Autumn tends to be a traveller's favourite, not only because of the great temperatures and low likelihood of rain, but also for the beautiful colours that paint the shores and bluffs of the Mississippi.
The Upper Mississippi (roughly north of St. Louis) enjoys its peak season from July through October, when temperatures are more moderate and the wildlife is most active. Meanwhile, the Lower Mississippi (south of Cairo, Illinois) truly shines during spring and autumn, when the oppressive heat and humidity of summer give way to gloriously comfortable conditions.
Mississippi River Cruises in Spring
Spring arrives on the Mississippi like a long-awaited friend, bringing with it a sense of renewal that's almost palpable. In May, New Orleans enjoys an average of around 24°C, Memphis hovers at about 22°C and St Paul sits comfortably in the low twenties.
The weather can be a bit of a mixed bag during early spring, with some days offering perfect conditions while others might bring a shower or two. Pack layers and a light rain jacket, and you'll be prepared for whatever Mother Nature throws your way.
The river comes alive with blooming dogwoods and redbuds painting the shoreline in delicate pastels, while migratory birds return to create a symphony of calls that accompanies your morning coffee on deck. It’s one of the best times to go on a Mississippi River cruise because of this seasonal display, combined with the comfortable weather.
What makes spring particularly special is the cultural calendar that unfolds along the Mississippi. The New Orleans Jazz & Heritage Festival is well worth planning your trip around if you're a music lover, with an impressive line-up each year. The Tennessee Williams & New Orleans Literary Festival is another standout, while Memphis hosts the World Championship Barbecue Cooking Contest.
However, spring does come with one caveat that's worth mentioning for Mississippi riverboat cruises. The season can bring higher-than-usual water levels, thanks to heavy rain or snowmelt, so there is a higher chance of flooding in the spring and a potential need to reroute or reschedule.
Don't let this scare you off, though. Cruise operators are incredibly experienced at handling these conditions, and you might even find that altered itineraries lead to unexpected discoveries.
Mississippi River Cruises in Summer
Summer on the Mississippi is when things get seriously toasty, especially as you head south. But don't write off summer entirely: there's something undeniably romantic about those long, lazy days when the living truly is easy.
If you choose summer as the best time to go on a Mississippi River cruise, the upper part of the river also typically experiences lower temperatures and less humidity in the summer, making it more enjoyable if you're looking for a river cruise during the warmer months of the year. Wildlife viewing is also at its peak in the northern reaches, where you'll spot bald eagles, river otters, and great blue herons.
July through September is a time when the weather is blissfully warm for a riverboat cruise on the Mississippi, but not as oppressive as summertime on the Lower Mississippi. If music is your mojo, this is a great time to experience the Mid-Mississippi River region on our Music Cities cruise from Memphis to Nashville.
The river comes alive with festivals, outdoor concerts, and that distinctly American summer vibe of barbecues and baseball games drifting from riverside towns. The natural world puts on quite a show as well, as lush greenery creates a verdant tunnel effect as you cruise between towering bluffs, and those famous Mississippi sunsets seem to last forever during the long summer days.
Just remember that if you're planning to venture into the Deep South during summer on cruises on the Mississippi, you'll want to embrace the heat rather than fight it. Summertime is only for those who love the heat, since the temperatures will soar during the day with high humidity. Think lightweight fabrics, plenty of sunscreen, and maybe a mint julep or two to help you cool down.
Mississippi River Cruises in Autumn
If you ask seasoned cruisers about the best time to go on a Mississippi River cruise, autumn will win hands down every single time. The weather is generally pleasant, or at least more mellow, throughout.
The practical benefits of Mississippi River cruises are also just as compelling as the aesthetic ones. Autumn tends to be a traveller's favourite, not only because of the great temperatures and low likelihood of rain, but also for the beautiful colours that paint the shores and bluffs of the Mississippi.
Sugar maples explode into brilliant reds, hickories turn golden yellow, and the river reflects this fiery canopy like a mirror. Cruise operators know this is their sweet spot, so you'll find the best selection of itineraries and the most experienced crews during these months.
Temperature-wise, autumn is one of the very best times to sail the Mississippi from start to finish. Mid-season, average highs sit around 26°C in New Orleans, 23°C in Memphis and about 15°C in St Paul. October, in particular, offers that perfect combination of warm days, cool evenings, and minimal rainfall that makes every moment on deck absolutely sublime.
Cruises on the Lower Mississippi are usually hosted in the fall, with the best months being October and November due to the high heat and humidity in the region. The crowds have thinned out from summer's peak, but the weather remains gloriously cooperative.
Mississippi River Cruises in Winter
The key to winter cruising on the Mississippi is understanding that winter works very differently depending on where you are on this massive river system.
The Lower Mississippi has the longest season, typically running from November through December and April to mid-June, with most sailings on the bottom one-third of the river (New Orleans round trip or New Orleans to Memphis). Down south, winter temperatures remain surprisingly mild, often hovering in the comfortable teens, making it an ideal escape from harsh northern winters.
Bear in mind that you’ll have fewer choices of Mississippi riverboat cruises in the winter, as it’s the off-season for many operators. But you'll have many attractions largely to yourself, and there's something profoundly peaceful about experiencing the river when nature has settled into its quiet season.
Holiday cruises on the Mississippi are becoming increasingly popular, as from December through early spring, the cities are alive with festivities. There's Christmas, of course, but more importantly, Mardi Gras, which usually falls in February or early March.
