This timespan can last months or just weeks. For instance, if a place's peak season is summer and its offseason is winter, then the shoulder season would be spring and fall.
Alternatively, a place may experience peak travel during a holiday weekend, but demand will drop off the weekend before or after — these times can also be considered shoulder season.
Here are five reasons why shoulder season is the best time to travel, especially during the pandemic.
1. Lower prices compared to peak season travel
Airfares averaged 23 per cent cheaper when booked for shoulder season versus peak season travel. That's according to a NerdWallet analysis conducted in December 2021 of more than 100 airfares taken from the most popular routes in the U.S. across eight major airlines.
The same routes were compared for flights booked for peak versus shoulder-season days, where peak season flights were those booked for the Monday before or after a major holiday. In contrast, the shoulder season flights were those taken two weeks before or after that date.
The difference was starkest around Christmas: Flights averaged 50 per cent cheaper when booked for Monday, January 10 versus Monday, December 27.
2. Less competition for reservations
Those higher flight prices typically stem from supply and demand — which means demand is higher during peak season.
Increased interest leads to more competition across the board, whether for a hotel room at the price point you want or the chance to nab tickets to that concert. And that's only scratching the surface.
Restaurants are more likely to get filled, aeroplanes to fly with fewer empty seats and wait times to get longer, and the likelihood of a complimentary upgrade diminishes.
Book during shoulder season and you'll vie with fewer folks for your top experiences.
3. You won't have as many 'offseason' closures
While demand is high during peak season, sometimes demand drops so low during the offseason that the places you want to visit aren't even open. Boat tour operators might board up for the winter, and charming ski town cafes could close for the summer.
For example, January in Utah's Zion National Park averages about 16 per cent of the number of visitors that come during peak season in July, and most tourists will have a rough go. Ice forces certain trails to close, some roads become inaccessible to drivers, and the museum and services like shuttle buses aren't available.
Yet, during the September shoulder season, crowds are at only about 85 per cent of the park's peak but most amenities are available. Plus, you'll benefit from mild weather and the emergence of fall colours.
Around the world, hotels often take the offseason to do renovations, so the pool might become off-limits. Airlines typically cut back routes, so you'll have less flexibility on what day or time you can fly.
But the shoulder season is less likely to entail such challenges.
Travel before summer crowds arrive and you might be pleasantly surprised with a newly renovated hotel room. Head to the mountains just after the winter holidays to take advantage of still-snowy slopes without as many skiers on them.
4. Weather is generally good
The shoulder season likely won't bring the sweltering heat or storms that come with a region's offseason. And in some cases, the weather during shoulder season is actually better than peak season.
Summer at Florida's theme parks is often humid and muggy — and that's before you add in the crowds of out-of-school kids.
During shoulder season, you might forgo sunny summer days on the beach, but you'll typically get temperate weather, not to mention a less sweaty smile in that photo with your favourite character.
Shoulder season in the Rocky Mountains might not entail the romanticism of white powder snow surrounding a cozy cabin. But, you can pack light and leave the parka at home.
5. More likely to experience unique events
Tourist hot spots typically want year-round crowds, so they often host events, concerts and other festivities that don't occur at times when crowds would be large anyway.
Theme park food festivals are among the most common shoulder season delights. Southern California theme park Knott's Berry Farm typically hosts its annual boysenberry festival from March to April.
Hawaii comes alive in the fall with festivals spanning multiple islands, including the annual Waikiki i Ho'olaule'a, which is a giant block party on Oahu, and the Kauai Mokihana Festival, a weeklong celebration of Hawaiian culture.
