Introduction
The luxury property market in Portugal continues to appreciate significantly, especially in the coastal areas. According to an analysis by idealista/data for the 2nd quarter of 2026, there are already three coastal municipalities where the median price of luxury homes exceeds €10,000/m² — two of them in the Algarve, surpassing even Lisbon. In this article, we explore the ranking of the 10 most expensive coastal municipalities in Portugal for luxury homes (properties over €1 million), based on the latest data.
The Ranking of the 10 Most Expensive Coastal Municipalities
According to idealista/data, this ranking refers specifically to municipalities with a coastline and considers "luxury homes" to be properties listed above €1 million. Here is the list, ordered by median price per square metre (2nd quarter 2026):
- Grândola — €14,286/m²
- Castro Marim — €12,626/m² (+4% in one year)
- Loulé — €10,804/m² (+19% in one year)
- Lisbon — €8,484/m² (+4%)
- Cascais — €7,971/m²
- Oeiras — €5,155/m²
- Sesimbra — €5,044/m²
- Porto — €4,977/m²
- Lourinhã — €4,040/m²
- Ílhavo — €2,406/m²
Important note: this list does not include Sintra, Aveiro, Coimbra or Figueira da Foz — municipalities that are not part of this specific idealista ranking. The previous version of the article contained this inaccuracy, which is now corrected.
Average Prices per Square Metre: The Highlights
The values confirm a significant disparity within the top 10:
- Grândola leads the way, with €14,286/m² — the highest value in the country in this segment, driven by the development of premium residential projects in Melides and Carvalhal, areas that benefit from the "Comporta effect" (although Comporta belongs to Alcácer do Sal, it attracts demand to neighbouring municipalities).
- Castro Marim, in the Algarve, comes in 2nd place with €12,626/m², reflecting a limited supply of premium developments compared to growing demand in a location between the sea and golf courses.
- Loulé closes the podium with €10,804/m² — one of the most consolidated luxury markets in the country, which includes Quinta do Lago and Vale do Lobo, anchors of the famous "Golden Triangle" in the Algarve, and records the largest year-on-year increase in the top 3 (+19%).
- Lisbon only appears in 4th place (€8,484/m²), being surpassed by two municipalities in the Algarve and one in the Alentejo — a fact that surprises those who automatically associate "luxury" with the capital.
Market Trends
Several factors are shaping this segment:
- Increasing international demand, including the so-called "Trump effect" — a reported increase in demand for luxury homes in Portugal from the US.
- Decreasing supply: despite Lisbon, Cascais and Porto being the municipalities with the largest stock of luxury properties listed (over 1,000 each), this stock has been decreasing over the last year, which tends to drive prices up.
- Broader national context: housing prices in Portugal rose by 6.8% in 2025, reaching a new historic high, with estimates pointing to growth of around 10% in 2026 — which would put Portugal ahead of Spain, the Netherlands and Poland in the European ranking of value appreciation.
- Location and exclusivity continue to be the main drivers of value appreciation: proximity to the sea, golf courses, and "territorial brands" such as Comporta or the Algarve's Golden Triangle.
