Travel to Taiwan on 14/6 to 22/6 .... How weather there...heavy rain? Typhoon ? Tks

It is too early to check the weather forecast, but according to the past weather records, it rains a lot during that time and most days are moderate rain. It will step into typhoon season then, but there is little possibility to have typhoon then. Anyway, the rainy days might ruin your trip. If you don't mind, change your trip to Nov. to next Mar. which is the best timing to travel there.
