The river's water temperature varies with the seasons, typically ranging between 5°C and 20°C (41°F to 68°F). During the summer, the water reaches its warmest temperatures, making it more appealing for recreational activities, while in winter, it remains cold and less suitable for such activities.

The Ahr Valley is known more for its hiking trails, vineyards, and natural beauty, offering visitors a chance to relax and explore the area rather than focus solely on water activities.
