Public holidays at Toronto move this destination's year too little to make it a different answer, so the Lisbon page is the one of record. This one is kept for the distance and the flight it implies.

No fare history on YTO–LIS yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in CA as well as at Lisbon, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

The year in Lisbon

Lisbon has a Mediterranean climate with mild winters and hot summers. The peak tourist season occurs in summer when the weather is warm and sunny, while spring and fall offer more moderate conditions and less crowding.

Busiest	early Jun to late Aug — Ideal summer weather, high demand among tourists.
Quieter, still good	early Apr to late May — Pleasant spring weather and fewer crowds. early Sep to late Oct — Milder temperatures and reduced tourist traffic.

This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
