Sightseeing pleasure flight in an small transport X over north side of rochester about 1500 AGL. Suddenly large balloon (later determined to be a WX balloon spc with something dangling several hundred feet below it) appeared at 12 O'clock high. Took evasive maneuver down and to the left when second balloon appeared below and to the right. This one was moored and I assume the one we missed came loose from its mooring. Second pass by confirmed these were WX type balloons and not carrying passenger. Suggest these balloons be reported to tower by ground operators when they leave their mooring and become hazard to aviation.
