Zadar weather in October

October here can be two different months and the board says so plainly: some years warm enough to swim anywhere along the coast, others cool and changeable and no use for swimming unless you are hardy. Our row lands on the better half, 21.8C over 16.2C with a sea still at 22.3C - above twenty being their own threshold for comfortable. Rain is 71mm across only 5.5 days. The change that actually alters a trip is the timetable rather than the weather: ferries move to the off-season schedule this month and the buses thin out with them, so the islands become quieter and harder to reach at the same time. Split itself stays open and busy into November. The record: humidity 75 percent, 8.8 hours of sun, an 18.1 kph wind and AQI 40.

Forum posters consistently name November as one of Croatia's rainiest months along the coast, with average coastal temperatures around 10C and often strong winds accompanying the rain. Posters are direct that many smaller towns and islands shut down for the season by November, with restaurants and boat tours largely unavailable, but note that larger mainland destinations like Zadar, Split and Dubrovnik stay open and can still offer genuinely nice weather between rain systems. Posters generally recommend sticking to these bigger coastal cities rather than island-hopping in November, since services there remain reliable even as the wider region turns quiet and wet. Posters generally rate November as manageable for visiting Zadar specifically, provided visitors pack for cool, changeable, occasionally windy and wet conditions and skip plans that depend on island infrastructure.

May is a fairly ideal month for the Dalmatian coast on the forum's telling — pleasant temperatures, far fewer tourists — with Zadar near 21°C and good bus connections down to Šibenik and beyond. Two honest caveats. The weather is genuinely unpredictable: one poster describes a week of lovely sun followed by a fortnight of cold and rain, and the record puts May at ten wet days. And the sea is the real catch, about 18°C, which regulars call too cold for comfortable swimming for most people. May here is a sightseeing month, not a swimming one.
