Visiting Lisbon in December 2026?

The busiest days are the 15th, 18th, 24th and 31st, and 1 more. Away from those, most days sit Calm. The calmest stretch is the 1st–14th.

Cruise ships are in port on 21 of 31 days; the heaviest is Thu 31 Dec, 2 ships in at once. Those mornings fill the squares first — start early, or save them for indoors.

The month is not one thing: its lightest day sits at 5% of the year and its heaviest at 98%, so where you land inside it matters. Daylight runs about 9 hours.

Either side of it, January is far calmer.

Calm for most of the month, but not all of it: 5 days run busy or busier — the heaviest are the 15th, 18th, 24th and 31st. Check the calendar before you fix your dates.

How does January compare? →

• The big-ticket sights are walk-ins now; the summer booking scramble is gone.
• Keep the days loose — decide over breakfast, not weeks ahead.
• Early on, you can have the busiest spots almost to yourself — bring a camera.

No queues to skip, and nothing to book ahead — that's the whole point.

Mild — around 16°C / 61°F, with a light jacket for the evenings, with rain on about 10 days, so keep a layer handy. Daylight is short, about 9 hours, so plan the big sights for the middle of the day.

• Lisbon gets rain on about 10 days in December, so the odds of being caught out are real. What earns its bag space is a shell that packs to nothing, dries fast and has a hood that survives wind; a heavy waterproof is overkill and an umbrella is one more thing to carry through crowds.
