The Winter Classic has become one of hockey’s most anticipated annual spectacles, blending tradition with the pure unpredictability of outdoor play. Since its debut in 2008, the outdoor stages have seen everything from sub-zero blasts to uncharacteristic mild spells.
Among the dozens of outdoor NHL games, a handful have flirted with warmth rather than winter’s bite. In 2020, Dallas hosted a Winter Classic under surprisingly mild skies, but it wasn’t the warmest test the league ever faced.
Looking back in the NHL’s outdoor record books, a 2016 matchup stands out: temperatures well above freezing turned a classic winter tradition into a near-springtime scene on the ice, rewriting what “winter” could mean.
The warmest NHL Winter Classic on record
While snowy New Year’s Days often define the Winter Classic’s iconic imagery, one edition stood out for a very different reason. The 2020 Winter Classic in Dallas, Texas, saw game-time temperatures hover near 55°F (13°C), unusually warm for a contest that trades its roots in frigid outdoor hockey for a spectacle in sun-splashed stadiums.

That Cotton Bowl showdown between the Dallas Stars and Nashville Predators brought a summer-like feel to a winter event. The mild air may have softened the frost on fans’ cheeks, but it didn’t cool the competitive fire on the ice, as the Stars captured a 4–2 victory in front of tens of thousands, a crowd that made it the second-most attended Winter Classic in league history.
The Dallas game’s warmth hinted at the NHL’s evolving relationship with outdoor weather, a dynamic balance between nostalgia and the realities of climate, venue and scheduling. Outdoor contests now embrace a range of conditions, from bitter cold to spring-like warmth, each leaving its own mark on the lore of hockey’s annual outdoor showcase.
The warmest NHL outdoor game ever played
Though the Winter Classic name is most often tied to January outdoor games, the broader series of NHL outdoor contests includes some even warmer days. On Feb. 27, 2016, at Coors Field in Denver, the puck dropped under skies where the thermometer read 65°F (18°C) — still the highest ambient temperature documented for an NHL outdoor game.

That Stadium Series matchup between the Colorado Avalanche and Detroit Red Wings turned tradition on its head, as attendees traded bulky winter coats for lighter layers under afternoon sunshine.
The Denver crowd, packed into the baseball park turned hockey venue, watched Detroit skate away with a 5–3 result amid conditions more reminiscent of spring training than a winter showcase.
While this wasn’t officially a Winter Classic under that specific name, its warmth still resonates when discussing the league’s experience with mild weather outdoor hockey, especially as the NHL looks ahead to even more southerly venues in future events.
