May I know the weather of taiwan between end of November to early December ?

Firstly, it won't be during the typhoon season, so your trip won't be bothered by that. Don't worry!

Generally, it will be cool even a little cold in late Nov. to early Dec. with the average temp of 16-18C. And it will be wet during that time, with frequent light rainfall, from which aspect, you'd better reconsider your trip.
