Wind 20 km / h – is it bad?
Constant wind with a speed of about 20 m/s or frequent gusts of 25-30 m/s. There is no appreciable threat to life or property from high winds. Sustained wind speeds are non-hazardous wind conditions that may still exist. Note: In strong winds, small branches break off trees and loose objects are blown away.
Is there a strong 20mph wind for planes?
Strong surface winds – 20 miles per hour or more – can make a bumpy launch, but only for a minute or two. Check the percentage of precipitation. A thunderstorm in this area can make the climb bumpy.
