No dimension, date or admission rule for the walls appears on this site, because none is in a source it can name and date. What is published is the day-night range: 6.8 °C at Dubrovnik in July against 8.6 °C on Hvar, so the early start buys less relief here.
Why the standard advice fails at this station
The advice given for the walls is always the same: go early. It is good advice in general and it is weaker here than almost anywhere else on the Croatian coast, for a reason that is in the published climate normals and in nothing else.
Dubrovnik has the narrowest gap between its mean daily maximum and its mean daily minimum of the three southern stations that publish a full record. The day does not cool down as far overnight, so the early hours start from a higher floor. Whatever you gain by arriving at opening time, you gain less of it here.
| Month | Dubrovnik day-night range | Hvar day-night range | Split day-night range | Dubrovnik overnight minimum |
|---|---|---|---|---|
| June | 6.4 °C | 8.1 °C | 7.9 °C | 18.9 °C |
| July | 6.8 °C | 8.6 °C | 8.3 °C | 21.4 °C |
| August | 6.9 °C | 8.7 °C | 8.0 °C | 21.6 °C |
| September | 6.7 °C | 8.3 °C | 6.9 °C | 18.4 °C |
In July the spread is 6.8 °C at Dubrovnik, 8.3 at Split and 8.6 on Hvar. In August it is 6.9 against 8.7. The city sits on an exposed southern coast with the sea against it on three sides, and that is exactly the configuration that holds overnight heat.
6.8 °C vs 8.6 °C
July day-night range at Dubrovnik and at Hvar — the early start buys less relief on this coast than on the islands
The practical translation is that the hour is a weaker lever here than the month, and that the month argument is settled elsewhere: August against September is the decision that actually changes what an outdoor circuit feels like, and that page carries the days-above-30 series in full. This page is about what to do once the month is fixed.
Treating an early start as the answer to a July visit
At Dubrovnik the overnight minimum in July is 21.4 °C and in August 21.6 °C. Those are the floors, not the walking conditions: by the time any outdoor circuit is open the station is already climbing towards a mean daily maximum of 28.2 °C. An early start on this coast moves you a couple of degrees, not a season.
What does move a season is the calendar. September’s overnight minimum is 18.4 °C and its mean maximum 25.1 °C, with 16.7 days still reaching 25. October drops the maximum to 21.1 °C but brings 120.1 mm of rain across 8.2 wet days and cuts sunshine to 6.1 hours a day from September’s 10.3. September is the window; the hour within it is a detail.
What is not on this page, and why
No length, no height, no circuit description, no ticket price and no opening hour. Not one of those is in a source this site can name and date, and the national Register of Cultural Goods holds country-level totals only — 8,999 entries and 31 UNESCO listings as at 4 August 2026 — which cannot be divided by a town, let alone by a monument.
That is a shorter page than most and a more useful one, because the omitted parts are the parts every competing page is recalling rather than checking. Dimensions and dates circulate in English travel writing with no source under any of them, and a figure nobody can attribute is not a fact.
- What is sourced: the day-night range at three southern stations, 6.8 °C at Dubrovnik in July.
- What is sourced: the overnight minimum, 21.6 °C in August and 18.4 °C in September.
- What is sourced: eight registered ferry routes touch the city and one carries a vehicle.
- What is not: any dimension, date, rule or price attached to the fortifications.
If the circuit is a fixed point of the trip, the sequence is: pick the month first, then the day of the week, then the hour. The full twelve-month record settles the first, the ferry calendar settles the second, and this page has settled how little the third is worth.
