September is the hinge of the Coimbra year twice over. The academic one restarts, bringing the students back and the Latada with them. And in 2026 the practical one restarted too: on 10 September the city switched on a rebuilt transport network and every set of arrival directions published before this month went out of date.
Summer opening hours run to the end of the month at most venues and then contract sharply on 1 October. September is the last month of the long evenings.
The transport change of 10 September 2026
Coimbra spent 2025 and 2026 converting a railway into a busway through the middle of itself. The switchover landed on 10 September 2026, when the Metrobus reached Coimbra-B and Praça da República.
The numbers, from the city council: weekday runs went from 291 to 452; average frequency on the urban section is five minutes at peak and 7.5 minutes off-peak; the vehicles carry 136 passengers. SMTUC monthly passes were accepted on Metro Mondego validators only until the end of September 2026, as a transition measure.
What this means for a visitor: the long-standing problem of getting from the mainline station into the city has effectively been solved. The old rail shuttle between Coimbra-B and the central station was permanently deactivated on 12 January 2025; the free Metro Mondego transfer for CP passengers replaced it, and now the Metrobus serves the station directly. Read the station guide before you travel.
Fares are the open item. Two weeks after a system-wide change we could not source a clean visitor fare table, and we are not going to publish one from memory. Use the city’s own mobility hub.
The Latada, and when it starts
The Festa das Latas is the autumn counterpart to the Queima: the welcome for new students rather than the farewell to finalists. The Câmara Municipal describes it as an October event, and the actual editions straddle the month boundary — the 2025 edition ran 29 September to 5 October, with the Sarau Académico on 29 September, the serenade at the Largo da Sé Nova at midnight on 1 October, and the Cortejo on Sunday 5 October at 14:00.
What happens: caloiros parade through the city in costumes devised by their senior padrinhos, with tin cans tied to their ankles — the municipality’s own phrase is “um cortejo bastante ruidoso”, a thoroughly noisy procession — ending with the freshers being baptised in the Mondego.
2026 dates were not published when this page was written, two weeks before the likely edition. That is a genuine gap: check the organisers rather than assuming the 2025 pattern repeats.
What closes at the end of the month
Two kinds of closure meet in late September, and both are worth checking before you book.
The festival closures. The university has published 4 October 2026 as a closure date for the Latada — the whole tourist circuit, including the Joanina Library. The Santa Cruz monastery closes on the Latada parade day too, which it lists as a movable date alongside Christmas.
The seasonal closures. On 30 September the Botanical Garden runs its last 20:00 evening — from 1 October it shuts at 17:30. The Sé Velha keeps summer hours through September and drops to a 17:30 weekday close from October. The Buçaco forest gates run to 19:00 through September and 17:00 thereafter.
The three indefinite closures continue: the Machado de Castro museum, Santa Clara-a-Velha and the University Tower.
Day trips, and one that is new
September 2026 is the first month in sixteen years when Lousã is a straightforward public-transport day trip from central Coimbra. The Ramal da Lousã railway closed in 2010; the Metrobus opened on the converted alignment on 16 December 2025, the Lousã–Serpins section reopened on 1 September 2026 after a landslide, and since 10 September the line connects into the city centre and the mainline station.
We could not source the Lousã timetable, fare or journey time — Metro Mondego’s site returned nothing when we fetched it. Nor does the Metrobus reach the schist villages themselves; it reaches the town. Getting up to Talasnal and the other hamlets is a separate problem.
Conímbriga runs its normal daily 10:00–18:00, and the SIT line 209 timetable in force from 4 September 2026 gives three buses each way, last weekday return from the ruins at 17:55. Aveiro and Figueira da Foz both still start with getting the station right.
