I am planning to go Hualien on 1Sep to 7Sep, how is the weather and will there be typhoon ? thanks.

The typhoon season lasts from June to September. It may rain often then, and the temperature may range from 80F to 85F. To be honest, it is not an ideal time for a visit. The best time is from March to May, and from October to December. So you are advised to change your plan a little bit.
