How it works
Every day of every destination gets one word — Calm, Lively, Busy or Packed — and here is exactly how we get there. No AI writes the word. It comes out of sourced data and the same arithmetic, run for every day the same way, with every stand-in labelled where a real number was missing. If you want to check our working, this is the page for it.
A crowd forecast, one day at a time. For every destination we take the things that actually fill a place up — the ships in port, the holidays travellers are on, the pull of the season — and we turn them into a single reading you can plan around. Four megaships in port on a Tuesday is not a guess. It is on the timetable. Our job is to add all of that up honestly and tell you what the day is likely to feel like.
Published cruise itineraries, cross-checked, each ship matched to its real size — we count berths, the beds on board, never a headcount of who actually sailed.
Official public-holiday and school-vacation calendars, for every country that sends visitors here and for the destination itself.
The shape of the year, drawn straight from the official visitor and overnight statistics kept by the people who count them — national statistics offices, tourism boards and ministries, and Eurostat. When there is a local source, we use the local source.
Weather comes from years of measured records, so we can tell you what a month is usually like. The named source behind each stream, live for this destination, is in the freshness list below.
We add the three streams together, but not equally — ships, holidays and the season don't push the same everywhere, and a cruise port and a mountain town are not the same place. So we work the mix out for each destination from its own signals: how much each one actually moves the crowd there. The starting importances are cruise 45%, season 35%, holidays 20%; each destination's real blend is worked out from its own signals and shown on that destination's page, never dressed up as something we measured. A confirmed event, like a festival with a date, can only ever push a day up, never down, and when it does you see it on the day itself.
Then comes the part that keeps us honest: we rank each day against the same destination's own year, and nothing else. A day is Busy here because it is busy for here — not against Venice, not against a world average. On a quiet island, "Busy" still means something.
The honest edges, stated plainly. This is a feature, not a footnote: we show the gaps, we never guess.
A day is scored from whatever signals it has, with the weights spread across what's actually there. If a day has nothing usable at all, we publish no reading for it rather than invent one. When we can't match enough of the cruise ships to a real size — below 70% — we call the ships "no data" instead of guessing how big they were.
An empty port is not a hole: "No ships scheduled" is a real answer straight off the timetable, and it counts. A hole is a hole, and we show it empty.
A quiet week can still be a miserable one — cold, wet, out of season. When that happens we say so, and we never wave you toward it as a good bet.
And day-trippers who arrive by ferry aren't in the count yet, so a coastal reading is a floor, not a ceiling — the real crowd may run a touch higher.
