Analysis

Fans and mobile air conditioners both showed sharp, near-simultaneous spikes at the 1–3 July heatwave, with mobile AC also rising into the August event. Sun protection followed a completely different curve: a smooth seasonal arc that peaked in May or early June and steadily declined through summer, regardless of temperature extremes.

Cooling gear vs. skincare: two entirely different demand logics

The contrast reveals two distinct purchasing logics within what is often lumped together as 'heat-related demand'. Cooling equipment — Ventilatoren and mobile Klimaanlagen — is bought reactively, driven by acute thermal discomfort. Germany's summer 2025 was defined by two DWD-documented heatwaves: the first peaked at 39.3 °C in Andernach on 2 July, with the national mean reaching 35.5 °C on that day. The second followed in mid-August. Both events generated immediate spikes in fan and mobile-AC purchasing. Sunscreen, by contrast, is a planned purchase linked to holiday season, UV forecasts, and leisure planning; shoppers stock up before beach or vacation trips, not in response to a Hitzewelle forecast. For retailers and category managers, this means fan and mobile-AC inventory must be positioned against real-time temperature alert systems — while sun protection follows conventional seasonal retail planning. This per-category breakdown complements the aggregate heatwave buyer share trend.

Methodology

Daily buyer shares are calculated separately for each of three categories — fans, mobile air conditioners, and sun protection — against a common denominator: all Amazon.de shoppers with any physical-goods order on that day. A 7-day centred moving average smooths day-of-week effects and absorbs the Prime Day buyer surge (8–11 July 2025). DWD-defined heatwave windows — 1–3 July and 10–18 August 2025 — are marked as orange reference bands. Category definitions follow curated product-name keyword lists; self-tanning products are excluded from sun protection. The observation period runs from 1 May to 14 September 2025.
