Eurostat data show how strongly platform-booked short stays concentrate in summer, and why that matters for owners who need their licence, registration and community authorisation in order before the peak.

2026 context: this analysis uses the Eurostat releases on short-stay accommodation booked through online platforms published between 2025 and 2026. The legal assessment of any property depends on its municipality, region and documents.

What the Eurostat data show

Eurostat publishes monthly data on guest nights booked through online platforms that share data with it (Airbnb, Booking and Expedia in the latest releases). In 2025, guests spent 951.6 million nights in short-stay accommodation booked this way across the EU, 11.4% more than in 2024.

The distribution through the year is very uneven. Between July and September 2025 guests spent 398.1 million nights, 8.7% more than a year earlier. Within that quarter, July grew by 10.0% and August and September by 8.0% each. The second quarter recorded 245.9 million nights and the last quarter 172.3 million, 10.9% more than in 2024. By subtracting these quarters from the annual total, the first quarter comes to roughly 135 million nights. This last figure is our own approximation from the published data. On that basis, July to September alone account for about 42% of the whole year.

How seasonality looks in Spain

Eurostat’s regional data show that the pattern differs from one destination to another. Andalusia recorded 7.7 million platform-booked nights in the first quarter of 2025, 13.3 million in the second and 19.5 million in the third, so its summer quarter is about two and a half times the winter one.

The Canary Islands show the opposite profile. They were the most popular region in the EU for platform-booked short stays in the first quarter of 2025, with 8.8 million nights. A property in the Canaries therefore faces demand and a regulatory context that differ from those of a Mediterranean coastal home, even though both belong to the same national market.

Seasonality is not only a commercial matter. It shapes several legal discussions:

  • Compliance before the peak. Demand concentrates in a few months, so problems with a licence, registration or listing tend to surface when the property is most heavily used. The review should take place before summer, not during it.
  • Data sharing. Under the EU framework, platforms must share information on hosts and units with the authorities. We explain it in our article on the EU data regulation on platforms.
  • Caps and zoning. Municipal limits, such as the 2% cap per neighbourhood in Valencia, or the debate on Barcelona in 2028, are justified largely by the pressure concentrated in certain areas and periods.
  • High season is not a seasonal lease. The fact that a stay takes place in July or August does not turn a tourist rental into a seasonal tenancy. In Spanish law the classification depends on the purpose and circumstances of the contract; see seasonal and tourist rentals in Barcelona.

Growth beyond the summer peak

The data also suggest that platform-booked stays are not limited to summer. The final quarter of 2025 was 10.9% above the same quarter of 2024 and more than 30% above 2023. The whole accommodation market, including hotels, grew more slowly in 2025: nearly 3.1 billion nights, 2.2% more than in 2024. Regulators and local authorities therefore see a segment that is growing faster than traditional accommodation and is not limited to the high season.

Limits of the data

The figures should be read with care. They only cover platforms that share data with Eurostat. They count guest nights, not properties or bookings, and they do not distinguish between licensed and unlicensed homes. The regional figures follow the EU’s NUTS 2 regions, which are larger than a municipality or a neighbourhood. They are a useful indicator of demand, not evidence of the legal status of any particular property.

What should an owner check before peak season?

  • That the tourism licence or registration is valid and matches the property and the activity.
  • That the community statutes and any recent resolutions allow the use.
  • That planning and municipal rules in the area have not changed.
  • That the registration number and information on every listing are correct and consistent.
  • That guest registration and tax obligations are up to date.

Conclusion

Eurostat’s numbers confirm that short-term rentals concentrate a large part of their activity in the summer quarter, with significant differences between regions. For owners, the practical consequence is to complete the compliance review before the peak rather than react to a request for documents in the middle of the season.
