European travelers are increasingly redirecting their summer holidays toward milder northern destinations as recurring heat waves make traditional Mediterranean hotspots less appealing. Tourism officials and data agencies are now tracking this as a structural change in travel behavior — a lasting shift in where and when people vacation — rather than a passing anomaly.

The European Travel Commission's 2025 data show that climate change affects 81% of travelers, according to reporting by Anadolu Agency (AA). European tourism officials say record heat waves are shifting travel patterns toward shoulder seasons (the periods just before and after peak summer) and northern destinations, as the so-called "coolcation" trend gains momentum across the continent (Yeni Şafak). By late July 2026, the trend had drawn sufficient attention to be covered as a sustained boom, with the Mediterranean retaining appeal even as northern alternatives attract growing numbers (Daily Sabah).

The Netherlands is one northern European country experiencing the effects of this redistribution. According to Statistics Netherlands (CBS), both Rotterdam and The Hague welcomed 1% more guests in 2025 than in 2024, while Amsterdam saw 9.5 million guests over the same period (CBS). CBS also reported that Dutch airports handled over 21 million air passengers in Q2 2026, a figure accompanied by a decrease in the number of flights, suggesting higher load factors — meaning fuller planes on the routes that remain (CBS).

The Hague, whose coastal districts of Scheveningen and Kijkduin are among the most visited stretches of Dutch coastline, has been preparing for intensified summer pressure. On 24 March 2026, The Hague & Partners kicked off the 2026 beach season with a new boulevard and festivals in Scheveningen, Kijkduin, and the city center (The Hague & Partners). The municipality's Coast Action Plan ("Actieplan Kust") lays out measures for summer 2026 covering both Scheveningen and Kijkduin, including mobility provisions for traffic, travel, and parking (City of The Hague). The plan notes that the beach and boulevard are popular with residents and visitors in the summer months, which sometimes causes nuisance (City of The Hague).

Crowd management has become a central operational concern. The Hague employs crowd control managers as part of its coastal action plan; Marjet de Jager, one such manager, described how enormous crowds toward the boulevard and beach were managed under the plan's framework (City of The Hague). On 6 June 2026, the municipality carried out a large-scale enforcement action in Scheveningen, citing that safety and livability are under pressure along the coastal strip, particularly on the boulevard, in the harbor, and in Duindorp (City of The Hague). The city also maintains a terrace policy ("terrassenbeleid") with rules for placing and using outdoor café terraces so that streets and squares remain accessible (City of The Hague).

Beyond leisure tourism, The Hague & Partners combines its strengths to attract and retain business visitors, conferences, tourists, and residents (The Hague & Partners). The organization inspires international visitors, businesses, and conferences to come to The Hague (The Hague & Partners), and the city welcomes international events related to New Energy, Finance, Legal, and Policy (The Hague Convention Bureau). The 6th Annual Global Legal Forum & Global Legal Excellence Awards are scheduled for The Hague on 5-6 March 2026 (The Hague & Partners).

The broader context here is that the convergence of climate-driven travel redistribution with municipal coastal management raises questions northern European destinations are only beginning to answer systematically. The 81% figure from the European Travel Commission is striking not because it confirms what observers have suspected, but because it quantifies the share of travelers whose decisions are now climate-influenced — a category that did not exist as a measurable variable in tourism economics a decade ago. Destinations like The Hague are effectively absorbing demand that was previously concentrated in the Mediterranean basin, and the infrastructure stress is visible in the enforcement actions, crowd control deployments, and mobility measures the municipality has layered into its 2026 coastal plan.

The decrease in flight numbers alongside rising passenger totals at Dutch airports is consistent with airline capacity discipline, but it also means that demand for northern European destinations is being met with fuller aircraft rather than expanded route networks. For municipal planners, this translates into concentrated peak-day pressure rather than evenly distributed seasonal flow, which is exactly the problem The Hague's Coast Action Plan is designed to address. The question worth watching is whether the coolcation trend stabilizes into a predictable seasonal pattern that infrastructure can accommodate, or whether it intensifies as heat waves become more frequent and severe, pushing northern coastal cities into a regime of perpetual peak-season crisis management.
