Nights, month by month
Nights spent at hotels, holiday homes, campsites and similar places in each region in 2025, and each month's share of that region's year.1 Unlike shares, the night counts can be compared between the two regions: they are the same measure.

What this cannot tell you
- Whole regions. A NUTS 2 region is large; a city or valley inside it can be much busier or quieter.
- Counted places only. Eurostat counts establishments above a size threshold, and regional data is sent once a year.2
- 2025 only. One year of visits; events and holidays move between years.
- No weather here. Regions are not matched to weather stations; see the Portugal page for weather.
Key takeaways
- Algarve: 22,941,654 nights in 2025; Grande Lisboa: 20,027,552.
- Busiest: Algarve August, Grande Lisboa August.
- Quietest: Algarve January, Grande Lisboa January.
- What we would skip: reading more nights as worse. A region with more nights may simply have more places to stay.
