What's the weather like in Zagreb by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Zagreb during May–Jun, Sep–Oct, Dec?
Excellent — chestnut and linden trees blooming in Maksimir, café terraces returning, lower prices than summer. Some rain but generally pleasant.
Shoulder season (Jan, Apr, Jul–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 (Feb–Mar) 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.
