Bornholm breathes with the sea

Bornholm – sea and cliffs in soft light

On Bornholm the climate is maritime: summers are comfortable and rarely hot, while winters are often milder than in Poland. The biggest difference? Wind — it keeps the air fresh and the temperature pleasant.

If you’re planning a trip focused on walking and cycling, aim for June–September. For a calmer vibe and beautiful light — spring and autumn are perfect.

“Layers instead of one heavy jacket — that’s the best Bornholm trick.”

  • June–August: beach season, long days, comfortable temperatures.
  • September–November: fewer visitors, beautiful colours, often windier.
