Manali is blessed with all season weather but if you're visiting there for "Rohtang pass" , Then you should go manali after may or Mid - may . So that you can enjoy the beautiful Rohtang pass.
Depends what you're looking for. I personally would prefer the month of December, where winter is at its peak. Rhotang pass would be closed though. The ideal season would be during summer.
Manali is best to visit during march to october as the weather is good. Most folks enjoy manali during new year time also as it snowfalls during that period.
October to February is the winter season and is considered to be the best time to visit Manali if you like the cold and January is best to enjoy the chilly pleasure of fresh snowfall . The temperature drops down below zero degrees Celsius.
