Current
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences
Rip tide
A rip tide is a specific type of current associated with the swift movement of tidal water through inlets and the mouths of estuaries, embayments, and harbors.
Channels & rivers - streams
Coves are safer to swim in versus channels
Currents can pull you down & hold you at the bottom causing drowning
Whirlpools & micro-whirlpools
Waves & cross wind waves
Water type & ecosystems + specifies
Sunlight + climate & temperature effects
Warm - Cold - Hot - Extreme Heat - Cool
Clouds + Risk of Hail + Waterspouts
Reading the waters & understanding all details effectively plus man-made & natural disaster or hazards
Marine + boating + mooring safety & marine first aid plus lifeguard swimming & diving knowledge - skill & ability
Fishing & numbers safety on catch + licencing requirements
Time of day + wind. Dust - Dawn
