How Window Light Changes Through the Seasons
A window does not provide the same light all year. The sun’s height, nearby trees and the length of the day can transform a bright winter corner into a shaded summer one—or the reverse.
Track the direct sun
Once a month, note when direct light first reaches the sill and when it leaves. You do not need a meter; a rough time is enough to reveal the pattern.
Watch deciduous trees
A window facing trees may receive strong spring sun before leaves open, then become softly shaded in summer. Plants near the glass may need to move as the canopy changes.
Notice heat as well as brightness
Summer glass can become much hotter than the room. A plant can have adequate light and still suffer from heat or dry soil beside a sunny pane.
Use the information around the room
Seasonal light can guide where you read, place plants, dry laundry or position a work table. Small furniture changes often make better use of daylight than adding more artificial lighting.
