What AI and Retail Data Tell Us About Summer Demand — and How to Stay Stocked When It Counts

Seasonal Demand Surges Are Predictable — And Manageable

Partnering with a major  U.S. retailer, we identified more than 100 products that consistently spike in demand during the summer months. These weren’t one-off promotions — they were everyday essentials tied to recurring seasonal behaviors. What stood out wasn’t just how frequently these items drive sales, but how easy they are to miss without precise forecasting.

These high-priority items clustered around familiar categories:

• Snacks (23 key SKUs)
• Beverages (including direct-store-delivery and refrigerated items)
• Bakery products (14 items)
• Frozen prepared meals
• Dairy staples

Together, these items represented over  $750,000 in missed revenue across just a segment of stores during peak summer weeks. That figure doesn’t capture total volume—it reflects just the recoverable upside from better availability on a curated set of risk-sensitive products. In a highly competitive retail environment, protecting those moments—when customers expect their go-to item to be there—can mean the difference between a completed basket and a lost customer.

Key insights from this seasonal readiness analysis include:

• Roughly 100 high-risk summer SKUs were identified using AI-powered predictive analysis based on prior stockout and sales velocity patterns, many of which had previously gone unnoticed in standard forecasts.
• On-shelf availability dropped sharply in the lead-up to key demand weeks, with some items falling up to 90 percentage points, despite being forecasted by vendors.
• Availability gaps remained 60 points below benchmarks even after peak weekends, highlighting the long-tail impact of poor execution timing.
• Early adjustments to planning and cross-functional alignment—tested during big events like the Super Bowl—helped stores prepare for summer surges with greater precision and fewer lost sales.

Smarter Forecasting = Better Shelf Execution

By identifying summer-sensitive products in advance—including those with a history of last-minute shelf gaps—our retail partners were able to revise seasonal forecasts and align those adjustments with vendor planning tools. These refinements improved accuracy and created clearer expectations across merchandising and store operations.

The results showed up on the floor:

• Fewer stockouts on summer staples
• Improved in-store execution during key weekends
• Reduced shopper frustration — and higher conversion at the shelf

In other words, when teams knew what to expect, they could act faster and execute better. 

Other Retailers Show Similar Patterns

This isn’t an isolated story. Across our other multiple large retailers, the same summer shopping patterns appeared, and so did the gaps. 

• At one national chain, stores that hit merchandising deadlines early saw 10–20% higher sales uplift than late movers..
• Regional execution mattered: some areas consistently outperformed others in stocking accuracy, leading to more reliable in-store conditions.
• One grocery-focused retailer saw in-stock availability drop to 78–82% for high-velocity items like frozen meals, beverages, and bakery products.
• And across just 400 stores, store-level opportunity scoring revealed $3.6 million in recoverable revenue—all tied to shortfalls in a small set of product categories.

These insights reinforced a shared theme: shelf success isn’t about stocking more—it’s about stocking smart, and stocking on time.

Why It Matters for Shoppers (and Retailers)

Every empty shelf sends a message. Shoppers expect their favorites to be there, especially before a holiday weekend or heatwave. When they’re not, it doesn’t just cost a sale; it costs trust. 

But thanks to better data and smarter forecasting, retailers can now close the gap between what customers expect and what’s actually available.

For shoppers, this means:

• Seasonal favorites stocked earlier and more consistently
• More reliable replenishment during long weekends
• Fewer last-minute letdowns in the aisle

And for retailers? It’s about more than just smoother execution. It’s a chance to retain loyalty in the moments that matter most—and to prove that operational excellence doesn’t just look good on a dashboard. It shows up where it counts: on the shelf.
