Mostar is mild, at about 9 °C (49 °F), but wet. Orthodox Christmas, on January 7, is a holiday in Republika Srpska and in Serb communities.
February
Still winter, with good skiing. The Sarajevo Winter festival of theatre, music and art runs from February 7 to March 21, 2027, and Ramadan is expected to begin around February 8, 2027; at sunset, Sarajevo’s old town fills with families breaking the fast. Hotels are cheap outside ski weekends.

May
One of the best months: about 25 °C (77 °F) in Mostar and 21 °C (71 °F) in Sarajevo, with long, bright days for the Old Bridge, Blagaj and the Kravica waterfalls before the summer crowds. Labour Day (May 1–2) is a holiday everywhere, and Kurban Bajram (Eid al-Adha) is expected around May 16, 2027.

Early summer: about 25 °C (78 °F) in Sarajevo and 30 °C (86 °F) in Mostar, warm enough to swim at Kravica, which stays open until 22:00 from June to September. On June 25, Međugorje marks the anniversary of the first reported apparitions, with a peace march from Humac the day before, and the village is very busy.
July
Hot and busy: Mostar averages 33 °C (91 °F) and often tops 38 °C (100 °F) at midday, and day-trippers from Croatia’s coast fill the Old Bridge area by late morning. The traditional Old Bridge diving competition is held in late July, and the Međugorje Youth Festival runs from July 27 to 31, 2027, earlier than usual. Sarajevo is pleasant, at about 28 °C (82 °F).
August
The hottest month in Mostar (about 34 °C / 92 °F) and the driest in Sarajevo. The Sarajevo Film Festival, the biggest in the Balkans, fills the city in mid-August (the 2026 edition ran August 14–21; 2027 dates were not yet announced), so book rooms early.

December
Winter returns, with snow in the mountains and the start of the ski season. Herzegovina’s Catholic towns celebrate Advent and Christmas (December 25), and Sarajevo’s markets and old town are festive around New Year.
Best time to visit by destination
Sarajevo
May, June and September for warm days and cool nights; August for the film festival; December to March for skiing at Jahorina and Bjelašnica, under an hour away. Winter can bring fog and air pollution on still days. See our Sarajevo guide.
Mostar
April to June and September to October. In July and August it is very hot and crowded, so see the Old Bridge early in the morning or in the evening, when the day-trippers have gone. Winters are mild but very wet. See our Mostar guide.
Međugorje
May, June, September and October for pleasant weather for the climbs up Apparition Hill and Cross Mountain. The village is busiest around the June 25 anniversary and the Youth Festival in late July. See our Međugorje guide.
North and central Bosnia
Jajce, Travnik and the Una valley around Bihać follow the continental pattern: May to September is warmest (Banja Luka averages about 30 °C / 86 °F in August), and winters are cold. Spring brings the fullest waterfalls and rivers.
Best time for hiking, rafting, swimming and skiing
Hiking
Late May to early October in the mountains, such as Sutjeska National Park and the highland village of Lukomir, when trails are free of snow. Stay on marked paths. See our hiking guide.
Rafting
April to June for the biggest water on the Neretva, Una and Tara; summer trips are gentler and warmer.
Swimming
June to September at the Kravica waterfalls and in Herzegovina’s rivers. The country’s short coast at Neum is warmest in July and August. See our beaches guide.
Skiing
December to March on Jahorina and Bjelašnica. For 2026–27, a peak-season adult day pass costs 98 KM on Jahorina and 69 KM on Bjelašnica, according to local press reports.
Seasons to plan around
Summer heat in Herzegovina (July and August): Mostar is one of the hottest cities in the Balkans. Sightsee early and late, carry water and rest at midday.
Winter in Bosnia (December to March): snow on mountain roads, with winter tyres compulsory from mid-November to mid-April, and fog and smog in Sarajevo’s valley on still days; people with breathing conditions should check air-quality readings.
Holidays in two entities: the Federation and Republika Srpska set their own public holidays, and Catholic, Orthodox and Muslim holidays fall on different dates, so check locally; museums, banks and some buses change their hours. In 2027, Ramazanski Bajram is expected around March 9 and Kurban Bajram around May 16, depending on the moon.
Border queues in summer: since April 2026, non-EU travelers are registered in the EU’s Entry/Exit System when they re-enter Croatia, and summer waits at the border can be long. The train from Sarajevo via Mostar continued to Ploče on the Croatian coast on Fridays to Sundays from June 26 to September 27, 2026.
How long to stay
Four days covers Sarajevo and Mostar; a week adds Jajce, Travnik and Herzegovina’s waterfalls and wineries; ten days to two weeks leaves time for rafting, the national parks or a loop with Croatia’s coast. Our Bosnia and Herzegovina travel guide has sample 4-, 7-, 10- and 14-day itineraries.
