How we calculate ski resort crowds

The crowd level on Afluencia Esquí is our own estimate for every day of the 2026-27 season. Here we explain what it measures, how it is calculated and its limits.

What the crowd level means

Each day has a level from 0 to 100 relative to the busiest day of that same resort (100 is its busiest day of the season). The levels are:

How each day is calculated

  1. Season total: we start from the figure published by the resort (visitors, skiers or ski days) when there is one, or from an estimate when there is not.
  2. Weight of each day: we combine the day of the week, the school calendars and public holidays of the countries visitors come from (Spain, France, the UK and others) and a season curve that rises between January and March.
  3. Split: the total is spread across opening days in proportion to that weight. If there is real data for a specific period, that period is fixed to the real figure.
  4. Level: each day is expressed from 0 to 100 against the resort’s busiest day.

Where the totals come from

Of the 57 resorts, 18 have a published real total, 12 have an estimated total and 27 have no published total (only the relative level is shown).

What it is not

How to use it

To plan, pick days with a low or very low level (usually midweek, in January and in March) and check slope status before you set off.
