When is The Best Time To Visit Bigfork, MT

Tucked away on a bay of the north end of Flathead Lake is the small but bustling town of Bigfork. Known for its laidback vibe, incredible natural bounty, and a populace obsessed with all things outdoors, Bigfork is a great place to base yourself while you’re visiting the Flathead valley.

Flathead lake is the largest natural freshwater lake west of the Mississippi and is one of the cleanest in the populated world. Bigfork’s location just adjacent makes it a perfect destination for freshwater fishing, wild swimming, and boating, but there are many attractions in town, as well.

If you’ve visited other cities in Montana, the weather in Bigfork might surprise you. While Montana is famous for its wildly swinging temperatures – sometimes brutally hot in the summer and freezing cold in the winter – you’ll likely welcome the Flathead Valley’s microclimate that keeps the weather a bit more moderate year-round.

If you’re unsure what’s the best time of year to visit Bigfork, here’s a brief rundown of the various tourist seasons, monthly weather, and calendar of major events.

Best Time To Visit Bigfork For…

  • Best Time to Book Hotels – While the least expensive time to book a hotel or a lodge is definitely January and February, many travelers are dissuaded by the cold, often snowy weather.

  • Best Time for Sightseeing – Thousands of tourists visit Bigfork and the nearby Flathead Valley and Glacier National Park in the summer, and you can avoid the bulk of them by visiting in June. While you may encounter a bit of rain, packing some rain gear will keep you comfortable if you get caught in an unexpected shower, and activities and tours are far less likely to be booked to capacity.
  • Best Time for Shopping – In and around Memorial Day is when you’ll see pop-ups like farmers, artists, and craft markets return for the season. Combined with the steep discounts you can find at national retailers over Memorial Day Weekend, it’s an ideal time to shop in Bigfork.
  • Best Time for Festivals & Events – Summer reigns for festivals in Bigfork, and when the weather allows, they love to throw them outdoors. Read on for a few picks for some of Bigfork’s best summer festivals.

Bigfork Travel Seasons

bigfork travel seasons

Unsurprisingly, Bigfork’s high season is during the summer. The warm weather attracts thousands of tourists to the adjacent Flathead Lake for boating, swimming, and fishing, and prices for rental cars, tours, and accommodations can skyrocket.

But you may find that the charms of summering lakeside outweigh the expense and the crowds, especially if you’re not a fan of weather over 90º, which is extremely rare in Bigfork (most summer days hover around 80º.) You’ll find the warmest, clearest weather between the beginning of July and the middle of August.

The low season is the winter when a lot of the lakeside recreation facilities close and locals tuck in for the season. Though outdoors pursuits are somewhat curbed by the weather, this is one of the most beautiful times of the year: the snowcapped mountains ringing the valley and the gentle, white snow cover can look magical. You’ll also likely find some steep discounts on accommodation in the winter, with prices sometimes half of what they are in July or August.

If you’re looking for the best mix of high vacancies, low prices, and fewer crowds, shoulder season is the perfect time to come to Bigfork. While the spring can be extremely rainy, the end of September and early October still boasts some warm days punctuated by crisp nights, and you’ll be spoiled for choice when picking a place to stay as the bulk of the summer tourists will be gone.

Fourth of July

Bigfork celebrates the nation’s birthday with an annual parade including floats and classic cars.

Ducks For Bucks

This annual rubber duck race along the Swan River is a beloved but quirky fundraiser for the Bigfork High School Scholarship Program. For $5, you ‘buy’ a yellow rubber duck that is released into the river after the annual Fourth of July parade. The first duck to pass under the Single Lane Bridge wins $200!

Festival of the Arts

This long-running arts fair is held every year over the first weekend in August. Alongside over 100 booths manned by local artists and artisans are live music, activities for kids, and plenty of food and drinks.

Rumble in the Bay Car Show
