  2. Beaufort: Force 8 Mean wind speed (knots): 37 Limit of wind speed (knots): 34 - 40 Description: Gale Sea State: Very Rough - High

  3. Beaufort: Force 10 Mean wind speed (knots): 52 Limit of wind speed (knots): 48 - 55 Description: Storm Sea State: Very High

  4. Beaufort: Force 12 Mean wind speed (knots): N/A Limit of wind speed (knots): Greater than 64 Description: Hurricane Sea State: Phenomenal Note: this use of the word “Hurricane” does not have the same meaning as its use in terms of a tropical storm

  5. Beaufort: Force 1 Mean wind speed (knots): 2 Limit of wind speed (knots): 1 - 3 Description: Light Air Sea State: Calm (rippled)

  6. Beaufort: Force 6 Mean wind speed (knots): 24 Limit of wind speed (knots): 22 - 27 Description: Strong Breeze Sea State: Rough

  7. Rapidly This term describes a weather system that is moving: “at 35 to 45 knots”

  8. Very High This is the term used to describe a wave height: “9.0 to 14.0m”

  9. Sea Fog A type of advection fog formed when air that has been lying over a warm water surface is transported over a colder water surface This results in cooling of the lower layer of air below its dewpoint

  10. Rapidly This term describes a weather system that is moving: “at 35 to 45 knots”

  11. Veering The changing of the wind direction clockwise

  12. Very Poor This term describes visibility of: “less than 1000 metres”

  13. Backing The changing of the wind in the opposite direction to veering (anticlockwise)

  14. Very High This is the term used to describe a wave height: “9.0 to 14.0m”

  15. Smooth This is the term used to describe a wave height: “less than 0.5m”

  16. Gale Warnings Are issued as required throughout the day (for winds of Gale Force 8 or more) These are displayed with the Shipping forecast

  17. Soon This weather changes is: “Expected within six to 12 hours of time of issue ”

  18. Moderate This term describes visibility of: “between 2 and 5 Nm”

  19. Rough This is the term used to describe a wave height: “2.5 to 4.0m”
