Meteo Zara in agosto

Plitvice-forum threads comparing mid-July against late August call the back half of August the somewhat better pick, crowds beginning to thin as the peak European holiday rush eases. Posters describe genuinely surprising morning readings even in August, one visitor reporting a properly cool start around 12 Celsius at the 7am opening before the day warms up considerably. Regulars are consistent an early arrival, ideally right at opening, remains the single best strategy for the narrow boardwalks that otherwise bottleneck badly between late morning and mid-afternoon. Booking timed tickets two to four weeks ahead is standing advice for anyone visiting in peak season. A two-day pass, allowing entry on separate days, is repeatedly recommended as a way to split the visit around the worst crowd windows rather than rushing through once. The record: 24C days feeling like 24C, 14.1C nights, an extraordinarily high 141mm across nearly 13 days and 73 percent humidity.

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.
