The best Months to dive in Grüner See

Grüner See, located in Austria, offers unique freshwater diving experiences marked by distinct seasonal variations. During spring, particularly May and June, the snowmelt from nearby mountains fills the lake, raising water levels and creating an underwater meadow landscape. Water temperatures range from 6°C to 10°C/43°F to 50°F, with visibility reaching up to 30 meters/98 feet, making these months ideal for diving. In summer, especially July, the water levels begin to recede, reducing the submerged areas but maintaining clear visibility. However, temperatures remain relatively cool, ranging from 5°C to 8°C/41°F to 46°F. As autumn approaches, the lake's water levels drop significantly, limiting dive opportunities. In winter, ice cover forms, making diving more challenging and generally less favorable. Thus, late spring to early summer remains the optimal period for divers seeking the best conditions at Grüner See.
