Just when modern merchandising and inventory management seemed sufficiently complex—navigating a shifting landscape of international tariffs, ongoing supply chain pressures, and steadily rising operational costs—along comes one of the most powerful El Niño weather disruptions on record. The upcoming season is introducing a massive wildcard into retail forecasting, forcing brands and supply chain executives to rethink their traditional playbooks for the critical fall and winter months.
El Niño is widely recognized as the warm phase of the El Niño-Southern Oscillation, a naturally occurring climate pattern characterized by rising sea surface temperatures across the central and eastern tropical Pacific Ocean. These temperature shifts set in motion a complex cascade of weather anomalies across the globe, with North America traditionally experiencing some of the most pronounced effects during the fall and winter months.
As a result, this year’s climate event—already dubbed the "Super El Niño" in various meteorological and financial circles—is destined to severely disrupt seasonal merchandising plans unless retailers take proactive steps to prepare for its unique regional impacts, according to Matthew Porcelli, a meteorologist and senior solutions engineer at The Weather Company.
Speaking in a recent video conference, Porcelli emphasized that the arrival of El Niño does not equate to a uniform blanket of warmth or wetness across the entire continent. Instead, its consequences vary dramatically depending on geographic location.
"It doesn’t mean collectively the country is going to be warmer or going to be wetter. El Niño has different effects depending on where you are around the country," Porcelli explained. "This is going to be a year that we’ve never experienced before, and anytime you’re in business, the goal is to reduce the amount of uncertainty to reduce the risk in your sales plans, and so we’re absolutely seeing that more than ever this year."
Running Hot
In recent months, market analysts and financial institutions have issued stern warnings that the Super El Niño could severely dent the bottom lines of brands heavily reliant on cold-weather apparel, heavy outerwear, and specialized winter sports gear.
The potential financial fallout has prompted searching questions from Wall Street. For instance, when discussing Kontoor Brands and its recently acquired Helly Hansen ski brand during an earnings discussion in August, BNP Paribas Equity Research senior analyst Laurent Vasilescu pressed company leadership for more detailed clarity regarding sales prospects for the upcoming season.
Vasilescu stressed that such forward-looking visibility is critical, noting, "This is particularly important as we think about a potentially very warm winter due to Super El Niño."
The sentiment was echoed in an August 24 research note authored by Wells Fargo analysts led by Ike Boruchow. The financial firm explicitly called out several prominent retail and apparel names—including Burlington, Deckers Outdoor Corporation, Canada Goose, and VF Corp. brands such as The North Face and Timberland—as being especially vulnerable to the anomalies brought on by the Super El Niño.
The vulnerability stems from varied business models and historical precedent. Burlington, for example, has traditionally relied heavily on robust sales of heavy winter coats and suffered notable financial impacts during a previous El Niño event a decade ago. Deckers faces the risk of having to implement steep, margin-eroding discounts on its popular Ugg footwear lines if December temperatures remain unseasonably high. Canada Goose, meanwhile, specializes almost exclusively in premium cold-weather outerwear, yet its corporate leadership has appeared slow to factor a significantly warmer winter into their operational planning.
Furthermore, VF Corp.’s flagship outdoor brands carry substantial downside risk from warmer weather patterns, a vulnerability that was clearly observable during both the 2015 and 2023 El Niño periods, which negatively impacted both overall sales volumes and gross profit margins.
"Historically, warm weather anomalies in critical winter months have had a clear impact on consumer spending related to softgoods," Boruchow stated in the research note, summarizing the core retail dilemma. "Consumers don’t buy coats when it is warm outside."
Running Cold
The disruptive reach of El Niño extends far beyond consumer demand, actively roiling global supply chains and inventory positioning. Successfully navigating this season requires a nuanced understanding of how anomalous weather patterns ripple through both manufacturing pipelines and retail storefronts. Protecting sales and safeguarding profit margins will depend entirely on how swiftly companies can adapt.
Because winter inventory is typically locked in well in advance of the season, retail operations often find themselves cornered. According to Wells Fargo’s analysis, unexpected sales misses, sudden inventory buildups, and hurried promotional markdowns designed to clear space for incoming spring merchandise become nearly inevitable when weather forecasting proves misaligned with pre-ordered stock.
However, Porcelli points out that while El Niño’s effects deviate from standard seasonal norms, the resulting patterns are broadly predictable for those equipped with advanced meteorological insights.
"Look at every quarterly report from the publicly facing retailers out there, and you will see them very often using ‘weather’ as an excuse for their sales," Porcelli observed, highlighting a persistent trend in corporate earnings calls.
Despite the inherent challenges, forward-thinking brands can prepare by recalibrating their expectations. For instance, businesses should anticipate that traditional hiking and camping seasons will extend much deeper into the calendar year. While the late-fall and early-winter holiday shopping period may track as unseasonably warm, historical modeling suggests that a sharp, sudden cold snap could still arrive early in the new year.
The overarching question facing retailers this season is organizational agility. Many companies risk panicking at the first sign of unseasonably mild December weather, leading them to prematurely discount winter stock.
"This could be potentially one of the top 10 warmest winters starting in the month of December, so some of the decision-making that can happen with retailers is they shift their inventory too early and move it to discount," Porcelli warned. "In this case, it would be much more worthwhile to keep a lot of that inventory around. Retailers can actually retain an edge by storing that inventory and waiting until that demand arises."
The Consumer
While the corporate outlook requires careful maneuvering, the Super El Niño may deliver some localized financial relief to everyday consumers, at least in the short term.
Household finances across the United States have faced mounting pressure from escalating utility and energy costs in recent years, according to recent research from S&P Global. Driven by expanding data centers, accelerating climate change, and various infrastructural pressures, utility rates nationwide have climbed by nearly 40% over the past six years.
However, warmer ambient temperatures during the autumn and winter months could translate into noticeable heating cost relief for residents in certain regions, according to a September research note published by Bank of America Institute analysts Liz Everett Krisberg and David Michael Tinsley.
At the same time, the climate pattern is a double-edged sword. "However, heavier rainfall and storms—particularly in the South—could leave some households facing repair costs, while longer-term pressures from climate change and rising electricity demand may continue to push utility bills higher," Krisberg and Tinsley cautioned.
When severe weather events or heavy winter storms cause widespread power outages, consumer buying habits shift instantly. Shoppers flood local hardware and home goods stores in search of backup generators and emergency supplies. Porcelli noted that local merchants must be prepared to stock exactly what consumers are searching for during these critical windows, allowing them to capture not only the high-value primary sale but also the inevitable add-on transactions that accompany emergency preparedness.
Beyond immediate utility savings and emergency retail spikes, El Niño is poised to alter consumer psychology in ways that directly impact discretionary spending. Rather than retreating indoors to stay cozy during frigid winter days, milder temperatures are likely to encourage consumers to get out and about, engaging in outdoor activities and social outings.
Data from surveys conducted by The Weather Company indicate that over a quarter of respondents explicitly report that pleasant weather conditions inspire them to spend more money. For a large segment of the population, the unseasonably warm conditions generated by the Super El Niño will register simply as good weather.
"Ninety percent of all decisions are made in the subconscious, and weather is one of the largest drivers of our behavior around the subconscious," Porcelli concluded.
