The best time to go to Borkum is during the summer months, from June to August, when the weather is at its warmest and sunniest.During this period, you can expect average temperatures ranging from 18°C to 22°C, superb for enjoying the island's expansive sandy beaches and outdoor activities. The North Sea water is also at its most inviting for swimming, and there are more hours of daylight for exploring. This is an ideal time for families looking for a classic beach holiday, with plenty of opportunities for sandcastle building, cycling, and water sports.Early autumn, specifically September, also offers a pleasant experience for couples. The crowds begin to thin out, but the temperatures remain mild, usually around 15°C to 18°C. This makes it a great time for long walks or bike rides along the dunes and enjoying the island's tranquil beauty without the peak season hustle.
