How to Show Wind Speed on a Weather Map
Although you could opt to show weather reading like temperature, precipitation and wind speed using tables or charts, one way to do so is by making a weather map. In addition to the fact that a visual representation is generally faster to read and interpret than a written one, your graphic will be of use to others, even if they don't speak English as their first language. Representing wind speed on graphs is easy to do.

Denote the location of low and high pressure systems on your map using uppercase letters "L" and "H," respectively. Wind occurs as a result of atmospheric pressure systems and in order to denote wind on a weather map, you'll need to have pressure systems shown as well.

Draw isobars, which are concentric rings (which may or may not be perfect) circles around your pressure systems to indicate the extent of the winds. Make your circles close together to indicate high wind speed and far apart to indicate lower wind speed, keeping in mind that one isobar may be closer to the ones inside and outside of it at a certain point around its periphery than at another.

Add arrows to your isobar to indicate the direction of wind speed. If you live in the Northern Hemisphere, you'll draw clockwise arrows around a high pressure system and counterclockwise ones around a low pressure system. If you live south of the Equator, the opposite holds true, with clockwise arrows reserves for low pressure systems and counterclockwise ones surround high pressure systems.
