Click on the Weather icon on the Live Map Toolbar. Then, tick the selection pin on the top right corner to activate Weather and choose the Wind barbs option.
Note: All registered MarineTraffic members have access to the Wind barbs layer, as well as a 24-hour wind forecast. However, members that have purchased the Weather feature can get wind forecasts for up to 60 hours! For more information about Weather, please click here.
Once you have activated the Wind barbs option and have selected your desired wind forecast time-frame, wind barbs will appear on the Live Map.
Note II: As with the vessel icons, you may need to zoom in enough in order to be able to see them.
The wind barbs have different colours and point to different directions. This way you are instantly able to get a picture of the overall wind conditions in any given area.
In the picture below, you can see the respective wind speed values in knots (1 knot = 1.15mph)
The direction the barb is pointing to, denotes the wind direction.
For example, the barb that is shown below represents a 35kn NE wind.
Spend some time to get accustomed to this feature and you will be able to easily identify wind conditions in no time!
Note III: Wind forecasts are model-based and not real-time observations sent by the ships. The maximum resolution of the weather data is 0.2 degrees (approximately 12 NM).
