What this solves
Portugal has 12–14 national + regional holidays per year, plus the saints' day of every city and town. The question is not "is the day off?" — most are. The question is "does this day in this city break the trip?"
The answer is yes for at least 5 days per year. São João in Porto (June 23–24) doubles hotel prices and closes half the restaurants. Carnaval in Loulé or Torres Vedras (announced each February) makes driving impossible. Easter Week (Carnaval + Holy Week + Easter) closes museums on the Sunday and Monday. Christmas + New Year closes nearly everything for 5 days.
This tool scores each major holiday against price, crowd, and closure for the city or region you choose, then surfaces the dates to avoid for your trip.

How to read the result
The result is a list of dates that fall in the chosen month for your region, each scored on three axes:
- Price multiplier (1.0–3.0) — how much hotels and flights cost relative to off-season. 1.0 is normal; 3.0 is São João in Porto.
- Crowd multiplier (1.0–3.0) — how busy the streets are. 1.0 is normal; 3.0 is fully packed.
- Closure multiplier (1.0–3.0) — how many museums / sites close. 1.0 is open as usual; 3.0 is closed entirely.
A "skip" recommendation means at least two axes are above 2.0. A "fine" recommendation means all three axes are below 1.5.

Limitations
- Easter is movable; the 2026 dates in this tool assume the Catholic calendar for 2026.
- Regional saints' days are not modelled. Every municipality has at least one — they affect that town only.
- The "Closure" axis does not include ferry cancellations, reduced metro, or strikes.
- Madeira has a separate holiday schedule (e.g. Dia da Madeira, Jul 1) not in the table.
- Hotel price ceilings are in many cases set by hotel chains at +20–50% above spot. The 3x number is for the worst-case boutique stay in Porto.
FAQ
Should I avoid São João in Porto?
Not necessarily — it's genuinely spectacular. But if you're a casual visitor who just wants a calm Porto weekend, book around it. Hotel rates 3x normal.
What happens on Easter Sunday?
Almost everything is closed. Public transport on Sunday schedule. Restaurants open but limited. Plan a walking-only day.
Are Christmas / NYE days worth visiting?
Yes for the lights, NYE party, and a quiet Christmas Day. No for the museums — almost all are closed Dec 25, 26 and Jan 1.
Which holidays are the best to visit?
Santos Populares (Jun 12–13) is the most fun in Lisbon. Carnaval in Loulé for the costumes. Santo António in Alfama is the most authentic festival.
