If you are moving through Dubrovnik, the Elaphiti islands, Mljet, Korcula, Hvar or Split by sea today, this is not a minor timetable wobble. Southern Dalmatia has already shifted into same-day disruption mode. Jadrolinija has interrupted both of its morning Dubrovnik-Elaphiti lines, TP Line is showing its Dubrovnik-Korcula-Hvar-Milna-Split line 842 as not operating, and Krilo has changed today's Mljet stop on its Split-Dubrovnik run from Pomena to Sobra because of strong wind.
Before you leave: if your day depends on a port transfer, a same-day island check-in or a catamaran connection, open the operator page again right before departure. This is the kind of weather setup where one route is cancelled, another is rerouted, and a nearby line still runs with a different landing point.

The DHMZ warning picture mattered on 16 May because the disruption was not theoretical anymore. Operators were already changing and cancelling sailings in southern Dalmatia.
What is affected right now
Operator | Route | Status on 16 May | What travelers should do |
|---|---|---|---|
Jadrolinija | 807 Dubrovnik - Kolocep - Lopud - Sudurad | Interrupted from 10:00, with return planned from Dubrovnik at 16:30 | If you are heading to the Elaphiti islands, recheck before going to port and do not plan on an early island crossing |
Jadrolinija | 831 Dubrovnik - Kolocep - Lopud - Sudurad | Interrupted, with return planned from Dubrovnik at 16:00 | Do not assume the passenger and ferry services recover at the same moment, check the official notice again before departure |
TP Line | 842 Dubrovnik - Korcula - Hvar - Milna - Split | Not operating because of windy conditions | If this was your through-route north, look at operator updates before building a same-day replacement plan |
Krilo | Split - Dubrovnik service on 16 May | Mljet stop changed from Pomena to Sobra on the 08:00 departure from Split | If you were planning to get off in western Mljet, confirm whether Sobra still works for your accommodation or onward transfer |
Why this matters more than a generic weather warning
The useful signal today is not just that DHMZ is warning of strong southerly and southwesterly wind, later turning northwesterly, with local storms across the Adriatic. The useful signal is that the warning has already split into three different real-world outcomes.
Jadrolinija is interrupting local Dubrovnik island services. TP Line is cancelling a longer inter-island and inter-city catamaran altogether. Krilo is still running, but with a port change on Mljet. That difference matters because many travelers build these routes as if all operators react the same way. They do not.
Who gets caught most easily today
The most exposed travelers are not only island hoppers doing a full coast chain. They are also the people with seemingly simple plans: a half-day out to the Elaphiti islands, a hotel check-in on Mljet, or a Dubrovnik to Korcula move that looked straightforward last night.
If you are trying to reach Korcula from Dubrovnik today, it is also worth keeping a backup arrival logic in mind instead of assuming a fast catamaran will save the day. Our practical route guide on how to get to Korcula without choosing the wrong arrival route is still useful on weather days like this because it helps you think beyond one sailing.
The practical move now
If you are starting in Dubrovnik, the first check should be the live operator notice, not a weather app. If you are already in transit, verify not only whether a route runs, but also where it now lands. Krilo's Sobra switch is a good example of a change that can still break the day even without a full cancellation.
This is also a day to avoid stacking a ferry, a timed check-in and another transfer too tightly. Southern Dalmatia is still moving, but not cleanly enough for minute-by-minute planning.
