What can hinder the visibility during wreck dives?

During wreck dives, visibility can be significantly hindered by factors such as silt and sediment. When divers penetrate wrecks or navigate near the seafloor, movements can disturb accumulated materials, creating clouds of particles that obscure visibility. This is particularly common in environments where wrecks have been submerged for extended periods, leading to the buildup of organic matter, sand, or mud. These disturbances can affect how light penetrates the water and can also make it difficult for divers to navigate safely.

Clear water, strong sunlight, and low water temperatures do not directly contribute to hindering visibility in the same way that silt and sediment do. In fact, clear water would generally enhance visibility, and while strong sunlight may create glare, it doesn't typically result in a lack of visibility like sediment does. Low water temperatures are primarily related to thermal comfort and do not inherently affect how well divers can see underwater.
