How do currents generally affect a dive?

Currents can significantly influence a diving experience by altering a diver's path and increasing air consumption. When diving in areas with strong currents, divers may find that they need to swim against the current or navigate around it, which can lead to a deviation from their intended course. This requires additional effort, naturally leading to increased exertion and, consequently, higher air consumption.

Moreover, managing one’s position in the water column against a current typically necessitates a greater physical effort to maintain control and avoid being swept away from the dive site or intended direction. For those unaccustomed to diving in current, this can also lead to a quicker fatigue since the diver must constantly adjust their position and direction, further resulting in accelerated air use. Therefore, understanding the impact of currents is crucial for planning a dive and ensuring that divers can manage their air supply effectively while navigating underwater environments.
