Wind can be described by its direction and speed. Wind direction is described using the
direction from which it is blowing. Westerly winds move from west to east, while easterly
winds move from east to west. Wind speed can be described using measurements like miles
per hour or levels on a scale called the Beaufort scale. The Beaufort scale divides wind
speeds into categories and uses specific words for different strengths of wind. A "breeze" is
a light wind, while a "gale” is stronger. On the Beaufort Scale, the strongest breeze is 31
miles per hour; any wind over 32 miles per hour is considered a gale. Though it isn't
included on the Beaufort Scale, “gust” is another word for strong wind.
