Pogoda Mostar — kwiecień

April here is a shoulder month in the strict sense: easier than summer on both temperature and crowds, and not yet open. Regulars warn that it is not beach weather - our row gives 19.8C air over a 15.7C sea - that many restaurants wait for May, and, most usefully, that the boats are on a winter timetable. The fast catamaran down to Dubrovnik does not start until May, the Ancona crossing skips the first twenty days of the month, and the island services run a reduced pattern. So an April itinerary has to be built from what is actually sailing. Weather is decent at 45.4mm across 5.6 days and 11.1 hours of sun. The record: 12.9C nights, humidity 70 percent and a 19.3 kph wind.

Forum posters describe Mostar's southern Herzegovina location as giving it a noticeably milder winter climate than northern Bosnia, with snow uncommon here - wind and rain are more likely worst-case scenarios for a December visit. Posters generally describe Bosnian winters as trending milder in recent years, though genuine surprises remain possible. Posters consistently note that the road into Mostar is well maintained and kept clear of snow even during winter weather elsewhere in the country, with rental cars typically supplied with snow tires as a precaution regardless. Posters generally rate December as a comparatively mild, manageable time to visit Mostar relative to the rest of Bosnia and Herzegovina, wind and rain the more likely weather challenge than snow or ice.

Mostar is the hottest place in Bosnia and Herzegovina — too far inland for the sea to cool it, and on a Mediterranean rather than a mountain climate — so June here reads very differently from June in Sarajevo. Days average near 28°C and the forum reports spells reaching 35°C; nights fall to about 16. The other June problem is size: the old town is small and gets completely crowded, with day-trippers off the Croatian coast and pilgrims bound for Medjugorje on top of everyone else. Regulars' fix is to stay overnight rather than day-trip, which also opens up Blagaj's dervish house and river source, and the castle town of Počitelj.
