The temperatures are comfortable for exploring the Jasmund National Park and its famous Königsstuhl chalk cliffs, with average highs around 15-20°C. It's a great time for hiking and enjoying the blooming nature without the peak summer rush.July and August are the warmest months, with average highs often reaching 20-24°C, making them great for beach activities and swimming in the Baltic Sea. The town is at its liveliest during this period, with many outdoor cafes and events. This is the peak season, so you'll find more visitors.September offers a lovely transition, with comfortable temperatures still suitable for outdoor activities, but with fewer tourists than in mid-summer. The autumn colours begin to emerge in the national park, creating a picturesque backdrop for walks.
