Astafyev Bay Beach is generally safe for swimming during calm summer weather. The clear, turquoise waters allow excellent visibility of the bottom, helping swimmers assess depth and conditions. The white sand creates a comfortable entry, though water temperatures remain cool even in summer at 18-22°C. The bay's protected nature typically means calmer conditions than open coastline. However, always check current weather and water conditions before swimming. Supervise children despite the appealing clear waters. The beach's remote location means lifeguards are unlikely to be present, so swim responsibly and never alone.

July and August offer the best conditions for visiting Astafyev Bay Beach, when weather is most stable and temperatures warmest. During peak summer, the turquoise waters are most vibrant under clear skies, creating the iconic views that make this beach famous. Water temperatures reach their annual peak, though still cool at 18-22°C. Early mornings and late afternoons provide exceptional light for photography of the clear waters and white sand. Weekdays are quieter than weekends. September can still be pleasant but cooler. Avoid visiting during stormy weather when access may be difficult.
