Sheep shearing is done in summer season i.e. during hot weather because they can survive without their thick protective coat of protective hair in summer season. If shearing is done in winter season, the sheep would die due to the severe cold.

What month do you shear sheep?

May marks the start of shearing season. Most farmers shear their sheep in late spring or early summer, when the weather turns warmer, to ensure sheep do not get too hot and start to attract flies.

How often is shearing done?

Typically each adult sheep is shorn once each year (a sheep may be said to have been "shorn" or "sheared", depending upon dialect). The annual shearing most often occurs in a shearing shed, a facility especially designed to process often hundreds and sometimes more than 3,000 sheep per day.
