It's a bit hard to say for sure, but typically the weather on Christmas can vary widely depending on where you live. In some places, it might be a bright and sunny day with temperatures in the 60s or 70s. In other places, it could be a snowy and cold day with temperatures below freezing. It's also possible that some parts of the world will experience both types of weather on the same day, as the weather can vary greatly depending on where you are.
