Why visit Mostar during Apr–May, Sep–Oct?
Excellent — comfortable temperatures, blooming pomegranate and fig trees, lower crowds than summer. May is arguably the best month for visiting.
Shoulder season (Mar, Jun, Aug, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Feb, Jul, Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
