Obtaining wind speed from a synoptic chart
The video below described how to interpret the wind speed from a synoptic chart. Remember it can only give a rough estimate of the likely winds that may be experienced at that position. Your synoptic chart must have a geostrophic wind scale in order to complete this calculation.
Wind direction from a synoptic chart
This method can be used to find the rough direction of the wind, it’s most accurate on open seas due to the fact coastal and land features can cause localised winds, especially around headlands.
