Halloween creep: How 'Summerween' is turning October into a four-month season

This behavioral evolution, detailed in a study by The Hershey Company and Morning Consult, reveals that the holiday is no longer a singular shopping event. Instead, consumers are treating Halloween as a multi-stage calendar of self-expression and community connection. Data indicates that 55% of parents now consider themselves in 'Halloween mode' before October, with 67% of those surveyed admitting they have already purchased seasonal candy during the summer months.

Stacy Taffet, Chief Marketing and Growth Officer at Hershey, notes that consumers are increasingly blending tradition with personal rituals. While 'Summerween'—a term familiar to 53% of Gen Z consumers—focuses on novelty and spontaneous enjoyment, the later weeks remain anchored in classic community participation like trunk-or-treating. This shift has prompted brands to move away from rigid seasonal marketing toward a strategy focused on 'Treatonomics,' where smaller, frequent purchases of snacks and treats serve to bridge the gap between summer and the final night of October.

Neighborhood dynamics are also central to this change. The report identifies that 41% of consumers define a 'perfect' Halloween block by high participation and community spirit. As expectations rise, the competition for the top treat spot remains fierce; Reese’s currently holds the title of America’s number one Halloween candy. With 71% of enthusiasts expressing high excitement for seasonal snacks, the industry is recalibrating its supply chains to match a consumer base that now demands Halloween-themed experiences long before the leaves begin to turn.
