Cost words compare a published regional accommodation level with Portugal's typical level, or describe a region's price season against its own year. The Cost score still uses Portugal's price level on the Europe scale; where regional money levels are unavailable, a cheaper season does not establish which region has the cheapest rooms.
Overall combines weather, crowds and cost. It is not a weather rating. By default, the list ranks weather first and shows Balanced Overall scores (50% weather, 30% crowds, 20% cost). Other priorities order it by your Overall mix. Missing cost is excluded and the available parts are reweighted.
Visitor season compares each region with its own year. A higher crowd score does not establish which place has fewer people in absolute terms. Regions cover whole statistical areas; open a guide for its geographic scope. Read the scoring method.
Weather across the country
Regional averages vary; check a forecast closer to your trip.
Ranges span available regional monthly averages, not daily extremes. A dash means a measurement is unavailable or withheld; individual guides explain the gaps.
Afternoons around 79°F (26°C): T-shirt weather; nights around 52°F (11°C): a sweater and a light jacket.

Before you go
The visitor season
May records 66% of August's overnight stays. This measures overnight demand, not queues or day-trippers.
Hotel prices
+19% on Portugal's historical national hotel-price index, versus its usual month in 2024–2025. This describes a price season, not a live room quote.
Published regional hotel revenue per guest-night ranges from €45 in Óbidos, Nazaré & the Tagus Valley to €106 in Lisbon. Óbidos, Nazaré & the Tagus Valley uses the 2024–2025 monthly average. Historical averages, not booking quotes.
Thinking about the coast?
Among beach-focused regions, the warmest measured seas this month are Madeira (68°F), The Algarve (64°F), Azores (64°F). Sea temperature is one part of a beach trip; open a region for weather and seasonal closures.
Holidays: 0% of people in Portugal live where schools are out on a typical May 2027 day. Public holidays: 1 May Labor Day; 27 May Corpus Christi. (School holidays: OpenHolidays, ODbL.)

Each row is a statistical region (NUTS 2); open it for the full month, the sources and what moving your dates would change. National lines are built from the regions: season is Portugal's total tourist nights this month against its busiest month (Eurostat, primarily 2024–2025; earlier published years where needed); weather counts regions whose displayed Weather score is at least 7.0/10 (very good or better) rather than averaging across the country; visitors ranks overnight visitors per resident against all Europe's regions (for a region) or the other countries (for Portugal) that month.
A regional accommodation level is shown only where publishable money data exists; elsewhere the cost words describe a regional season against its own year, and the score starts from the national price level. Separately, Portugal's 2024 restaurants-and-hotels level is well below EU average (76 where the EU average is 100). Full method.
