The wind of Phagan blows; the head gets covered with dust.

This couplet vividly paints a picture of the month of Fagan, which typically falls around February and March. During this time, the winds are often quite strong and dry. These powerful Fagan winds stir up a lot of dust from the ground, causing it to swirl in the air. As a result, anyone caught outdoors or working in such conditions might find their head and hair getting covered or 'caked' with this airborne dust. It's a simple, relatable image of how nature impacts our daily lives during a specific season, highlighting the dusty reality of the Fagan winds.
