What's the weather like in Bornholm by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Bornholm during Jun–Sep?
The peak season. Long bright days, warm seas at Dueodde and Sandvig (16-18C), and the smokehouse-and-beach circuit in full operation.
Shoulder season (May, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Apr, Nov–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.
