✦ Go in June or September for the best mix of decent weather and manageable tourist numbers.
✅ Best months
June and September: June has long daylight and pleasant warmth without peak crowds; September offers calm weather before the autumn chill sets in.
🔥 Peak season
July: schools are out across Denmark, and the Bornholm Rundt sailing race and summer markets fill the island. Hotel prices jump by 40-60% and advance booking is essential.

🌙 Quietest & cheapest
