The weather on Christmas day is a mixed bag, my dear. It's a magical time of year, when all sorts of possibilities can happen. But if you're looking for a more concrete answer, I can tell you that it's usually quite cold and snowy. The snowflakes twinkle in the sunlight, giving the world a beautiful, wintry glow. And the air is crisp and fresh, making it the perfect day to enjoy hot chocolate and cookies by the fireplace.
