Question: I am interested in summitting Breithorn this winter (late January) using crampons and an ice axe. I am in excellent physical shape but I do not have much alpine experience. I have seen mixed reviews about whether or not I should hire a guide, but most companies do not offer tours in the winter. I am curious why this is the case and if I should even think about summitting Breithorn in the winter, and if I should even consider doing it by myself.

Climbing the Breithorn in the winter is a much different matter than in the spring or summer. Any 4,000 meter peak in the alps is subject to arctic weather conditions with high winds and temperatures far below freezing. There is also going to be very deep snow, so unless you know how to ski or snowshoe, you are going to have a rough time even getting to the real start of the climb. If you've never tried to travel on foot in 2 meters of soft snow, you have no idea of how slow and exhausting it is. On top of that, a 35 degree slope is going to have significant hazards from avalanche. Until you have enough experience to evaluate the local avalanche forecasts and compare them to the conditions you actually see, you should be very conservative in your winter travel.

That being said, the Breithorn is considered the easiest 4,000 meter peak in the alps, but it still involves glacier travel and somewhat steep (35 degree) snow slopes. That makes it an excellent choice for a beginner (with a guide if you're a real beginner) in season (spring and summer).
As a general rule, I think it unwise to attempt, solo, for the first time, the sort of climb that one has no experience with, especially if it carries the potential for a serious accident.

You have winter against you, ice against you, inexperience against you, and possibly an unknown reaction to 4,164 meters against you. Solo? No, not unless your meaning of *do not have much alpine experience* is an extremely modest understatement.

As for hiring a guide, it is likely that a company will be able to find a guide for you, even if they do not regularly offer tours in the winter. You will be hiring a private guide and it will be more expensive than the summer tour. The reason that the companies do not offer regular tours is probably because there are not enough tourists who are able to climb a mountain in winter conditions.
