Is it possible to climb Huayna Potosi, Bolivia in December?

Does anyone know if there are tours to climb Huayna Potosi in December? The tours I found online where only till November but I found some comments stating they climbed Potosi in December or January.

If it’s not possible does anyone know a similar peak (in sense of technical difficulty) in:

Peru climbable in November

Bolivia climbable in December

Chile/Argentinia climbable in January

I’ll be backpacking down to the south so if anyone has better recommendations I could also bend the times a little bit.

Yes. I’ve talked with local Bolivian and Ecuadorians who have climbed in the Bolivian Andes all year round. The weather might be more variable in the rainy season. I’ll be there in November.
