Home / EES queues / Porto
Porto (OPO) is a popular summer-holiday airport in Portugal. As a non-EU traveller you now pass through the EU's Entry/Exit System (EES) at the border here. This page covers when the border is busiest and quietest, and links you to an estimate for your own date and time.
Check Porto for your date and time →Based on 19 days of scheduled departures, here is how border pressure at Porto tends to fall across a typical week (how we work this out). It is a pattern, not a promise, and a one-off day can look nothing like it.
Pressure is usually heaviest between 09:00 and 11:00, when departing non-EU passengers bunch up at the border together.
While the airport is properly open, the lightest stretch is typically between 12:00 and 14:00.
Sunday is normally the heaviest day of the week at Porto, and Wednesday the lightest. If your dates are flexible, that difference is usually worth more than the hour you pick.

It gets busy through the summer holidays. EES queues are usually manageable off-peak, but they can build quickly when departures bunch together.
There is no single right number. For your exact time, our tool estimates how busy the border is likely to be, from Very low to Very high, based on the non-EU flights sharing the hall with you.
See Porto's queue estimate →The first time you cross a border under EES, your fingerprints and photo are captured and stored, which takes a few minutes per traveller. That is fine for one person but adds up when a terminal of non-EU passengers arrives in the same hour. Once you are enrolled, later crossings are quicker, because your details only need to be verified.
Yes. Porto Airport is in Portugal, which operates the EU's Entry/Exit System. Non-EU travellers, including UK passport holders, are registered by EES on entry to and exit from the Schengen area, so it applies whether you are arriving or heading home.
There is no honest fixed figure, and nobody outside the border hall can give you one in minutes: how fast the queue moves depends on how many desks are staffed at that moment, which is not published anywhere. What can be worked out in advance is how crowded the border will be, because flight schedules are known. That is what we predict for Porto, from Very low to Very high, for your own date and time.
