This is normal. Idle speed also changes with altitude. And the drag on the engine from oil viscosity in the engine and transmission is higher. Normally for winter I set my idle up to 1200, so I don't have to worry about stalling. A also want less engine braking since tires will be cold. When real cold I may leave the fast idle lever up all the time.
