Usually, no. Monitor calibration is normally set to a standard target, not adjusted for the season. A 6500K white point is commonly used for screen-to-screen consistency, while 5000K is often used when matching a display to print viewing conditions.

Ambient daylight color does change a lot, but mostly because of time of day, weather, dust, and water vapor—not because of the season alone, and not in any meaningful way from global warming for monitor calibration purposes. Daylight at one location can vary far more within a single day than between seasons.

So the practical approach is to choose the white point that matches your workflow:

• 6500K for general display use and consistency with most monitors
• 5000K if you are editing specifically to match prints viewed under standard print lighting

If your room lighting changes dramatically, control the room lighting instead of changing calibration targets seasonally.
