i m planning my trip to Taiwan from 23rd to 29th august 2016, pls advise is it wise to go?

To be honest, it is not an ideal time. In late August, it will rain a lot, and the temperature may range from 80F to 85F. It is hot and moist. And the possibility of typhoon will be high during that period of time. It will influence the sightseeing a lot.

Generally speaking, the best time lasts from March to May, and from October to December when the weather is favorable and the scenery is beautiful. You may consider changing your plan. :)
