Is September 2027 a good month to visit Tallinn?
Busy — the typical September day in Tallinn is busier than 78% of its year.
If you are coming for something that only happens in September, that is the trade. If not, January is quieter.
Calm · Lively · Busy · Packed rank a day against Tallinn's own year — not a headcount.
This month's verified events: Swedbank Tallinn Marathon weekend (10–12 — expected).
September is one of Tallinn's busiest months: mild and wet, around 16°C / 60°F with rain on about 13 days, and Busy on 10 of 30 days.
No. The typical September day in Tallinn is Busy, and 19 of the 30 days in our window run Busy or Packed, so most days feel crowded. Expect around 16 °C by day, with rain on about 13 days. The crowd comes with the school holidays in Germany. Cruise ships call on 15 of the 30 days, 2 at once on Monday 27 September. The autumn trough for foreign visitors falls on 1–30 September. Mid September is the month's quietest stretch in Tallinn — the typical day at 58%, against 79% in late September. The crush is at the Viru Gate passage; the quiet is at the Old Town before nine. The calmest day is Wednesday 15 September, the busiest Friday 10 September.
In short, a hard sell — heavy crowds without the best of the weather.
Among the 12 months we forecast for Tallinn, September ranks 8th for crowd pressure. Its heaviest day is Fri 10 Sep, busier than 99% of the year; its lightest is Wed 15 Sep at 37%.
Preparing pays off in a month like this: timed-entry tickets and pre-booked tours turn the queue time into sightseeing time. see the options →
Pack for wet first — rain on 13 of 30 days.

How busy is Tallinn in September?
The busiest days are the 10th, 11th, 12th and 23rd, and 15 more. Away from those, most days sit Lively. The calmest stretch is the 18th–20th.
Cruise ships are in port on 15 of 30 days; the heaviest is Mon 27 Sep, 2 ships in at once. Those mornings fill the squares first — start early, or save them for indoors.
The month is not one thing: its lightest day sits at 37% of the year and its heaviest at 99%, so where you land inside it matters. All four Tuesdays run Busy or Packed. Daylight runs about 12 hours.
Either side of it, August is busier still and October is busier still.
The calmest days are the 15th, 16th and 18th — aim for those if your dates can flex.

Which week of September is quietest in Tallinn?
Mid September is the month's quietest stretch in Tallinn — the typical day at 58%, against 79% in late September.
Can't move the dates? How to avoid the worst crowds
- The heaviest port day is Mon 27 Sep — 2 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- Need flexibility? The 18th–20th is the month's calmest stretch — the easiest window to move around in.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.
Travelling on a busy day?
Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.
September weather in Tallinn
Mild — around 16°C / 60°F, with a light jacket for the evenings, with rain on about 13 days, so keep a layer handy.
Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
