Is May Right for You?
Weigh the advantages and considerations before booking
- + Bismarck in May feels like the city is finally waking up. After the deep freeze, which lasts into April, you get those first warm afternoons where a cotton shirt is enough, and the Missouri River starts to look inviting again, not just frozen and forbidding. The parks downtown and along the riverbank, which are dusted in snow or barren mud for so much of the year, suddenly explode with that electric green of new grass.
- + The crowds haven't arrived yet. This is the quiet, local version of Bismarck, before the summer vacation rush. You'll have Sertoma Park's trails mostly to yourself, and you can get a table at any of the long-standing local diners downtown without that weekend wait that builds by June.
- + May marks the start of the proper outdoor season without the stifling humidity and heat that can settle in by July. It's the perfect window for the longer hikes out at Fort Abraham Lincoln State Park, where the wind through the cottonwoods makes a sound you can only hear before the cicadas start their summer drone, and the reconstructed Custer-era cabins don't feel like baking ovens.
- + The light in May is something else. The sun sets late, painting the plains west of town in those long, golden-hour stretches where every blade of prairie grass seems backlit, and the air is so crisp and clear you can see for miles from the bluffs overlooking the Missouri. It's the kind of light that makes photographers pack extra memory cards.
- − You have to pack for three seasons, maybe in a single day. A morning that starts at a brisk 45°F (7°C) can climb to a sunny 65°F (18°C) by lunch, only to have a cold front sweep in from the west by dinner, bringing a wind that cuts through a light jacket. Layering isn't a suggestion. It's a necessity.
- − While officially shoulder season, the weather's unpredictability means some seasonal attractions are still in a state of 'maybe.' The paddlewheel boats on the Missouri might start running in late May, or they might be delayed by high, cold water. Some of the smaller, locally-run outdoor tours are still getting their staff and schedules sorted, so availability can be spotty.
- − The landscape is caught between winter's end and summer's start. If you're imagining lush, flower-filled prairies, temper your expectations. Early May can still look brown and beaten down from winter, with the real explosion of wildflowers not hitting until June. The green arrives, but it's a shy, tentative green at first.

Best Activities in May
Top things to do during your visit
This is the absolute best month for tackling the trails that climb the bluffs along the Missouri River, like those in the McDowell Dam Recreation Area or across the river in Mandan. The biting insects haven't hatched in force yet, the prairie rattlesnakes are still sluggish, and the temperatures are cool enough to make the steep climbs enjoyable rather than punishing. You'll get panoramic views of the wide, winding river valley without the summer haze, and the scent is all thawed earth, sage, and the faint sweetness of budding chokecherry bushes.
Exploring Bismarck's compact downtown core on foot is a May specialty. The historic buildings along Broadway (the art-deco Patterson Hotel, the sandstone block of the former Provident Life building) look their best in the gentle spring sun. The air carries the smell of coffee from the old-school shops mixed with the damp-earth scent from the newly-watered planters. This is when locals reclaim the sidewalks, so you'll get a feel for the city's pace and character without fighting through summer tourist throngs.
The well-known paddlewheel riverboats on the Missouri typically begin their season in late May, and catching one of the first cruises of the year is a local rite of spring. The river is often high and swift with snowmelt, making for a powerful, scenic ride. The air on the water is still fresh and cool, good for standing on the outer deck. You'll hear the deep-throated call of Canada geese and see bald eagles perched in the cottonwoods, all set to the rhythmic splash of the paddlewheel (a sound that embodies river travel history).
Rent a car and drive the backroads southwest of Bismarck, towards the tiny town of New Salem and the surrounding ranchlands. In May, the rolling hills are coming alive, and you'll see newborn calves in the pastures and hawks circling on the thermal winds that rush across the open land. The sound out here is just the wind and your tires on gravel. Stop at the Enchanted Highway market if it's open for a slice of homemade pie and a chance to see the world's largest scrap metal sculptures against the big, changing sky.
North Dakota's art-deco capitol building, known locally as the "Skyscraper on the Prairie," sits amid large grounds good for a leisurely May stroll. The reflecting pool is usually filled. The dozens of American elm trees are leafing out. The 19-story tower looks sharp against the bright blue sky. Inside, the marble halls stay cool and quiet, smelling of polished stone and old paper. The free tours draw fewer visitors now than in summer. You might get a guide all to yourself.
