You may not experience snowfall at the moment, but you will be able to find snow in Manali.
Also, the destinations that you have mentioned are very popular hill stations in North India. Hence, you might also find a lot of crowds there. I have attached three articles below that give you alternatives for offbeat places instead, such as Jalori Jot, Chamoli, Tirthan Valley and more. Most of them are not difficult to reach as well hence you could consider going to a lesser-explored destination this time.
