How Sun Angle Varies in Poland Through the Year
Poland sits between approximately 49°N and 54°N latitude. At this latitude, the sun's path across the sky changes significantly between the summer and winter solstices. In June, the sun rises in the northeast and climbs steeply; in December, it rises in the southeast and stays low throughout the day.
For an east-facing window, this means:
- In summer, direct sun enters the window at a relatively high angle, creating a narrower beam that moves quickly across the floor
- In winter, direct sun enters at a low angle, casting a longer beam that penetrates further into the room and produces stronger contrast between lit and shadow areas
- In spring and autumn, conditions fall between these extremes
The IMGW (Institute of Meteorology and Water Management) publishes solar radiation data for Polish stations that confirms the seasonal difference in radiation intensity across the country.
What This Means for a Desk Near an East Window
A desk placed directly in front of an east window in summer will receive direct sun for one to two hours after sunrise. In June in Warsaw, that sunrise is around 04:15, so the direct sun phase ends before most people begin working. By 07:00, the direct sun has moved past a true east window, and only bright indirect light remains.
In winter, sunrise in Warsaw is around 07:45. If you are at your desk at 08:00 in December, you may have direct low-angle sun coming in at eye level. A low winter sun at an east-facing window produces significant glare if you are facing the window, and strong shadows if the light comes from the side.
Avoiding Glare at a Screen
Screen glare from direct morning sun is a practical problem in east-facing rooms in autumn and winter, when the sun rises late and low. Positioning the desk so the window is to the side rather than directly behind or in front of the monitor reduces reflections. A secondary benefit of this arrangement is that the screen does not block the window's natural light.
Thin diffusing curtains or a sheer blind can reduce direct sun intensity without eliminating the daylight. This is a common solution in Polish apartments where east windows are also the primary source of morning light in winter.
Reading Chairs and Natural Light
A reading chair benefits from natural light that falls on the page or screen from the side or slightly from above — not directly into the reader's eyes. Near an east window, a chair positioned so the window is 45–90 degrees to the side, at roughly shoulder height, uses the morning light effectively without producing direct glare.
In summer, the bright morning light at an east window is generally sufficient for reading without supplemental lighting in the hours after sunrise. In winter, the low-angle sun creates contrast problems, and a reading lamp placed to the side of the chair becomes the more reliable light source.
Ceilings, Reflective Surfaces, and Light Depth
The standard Polish apartment block construction of the 1960s–1990s includes relatively small windows and rooms with limited depth. In these rooms, an east window provides adequate natural light close to the glass, but levels drop significantly beyond one metre. White or light-coloured walls and ceilings improve the distribution of morning light by reflecting it further into the room.
Newer construction — particularly post-2000 apartments in Warsaw, Kraków, and Wrocław — tends toward larger window openings, which increases the range of effective natural light at east-facing windows.
Seasonal Adaptation
A workspace that works well in summer near an east window may need adjustment in winter. The practical variables are desk angle relative to the window, curtain or blind use during the first hour after sunrise, and supplemental lighting for the extended dark mornings of November through January.
Measuring the lux at your desk at the times you typically work, in both summer and winter, gives you concrete information for these decisions. The light measurement article describes how to take those readings.
Plants and Workspaces Together
East-facing rooms that combine a reading workspace with indoor plants benefit from placing plants on the windowsill or a shelf at the glass, where light levels are highest, while the desk is positioned to the side. This arrangement captures the morning light for both plants and the workspace without conflict. For plant options suited to this setup, see the plant selection article.
