Temperature in degrees Celsius (°C) may be converted to degrees Fahrenheit (°F) as follows:
°F=(1.8×°C)+32
Temperature in degrees Fahrenheit (°F) may be converted to degrees Celsius (°C) as follows:
°C=(°F-32)/1.8
Wind direction is the direction the wind is coming from in degrees clockwise from true north.
Wave direction is the direction from which waves are propagating, measured clockwise from true north.
Wave period (length of time taken by one cycle) is given in seconds.
Salinity is given in practical salinity units (psu). |
