If you check the weather forecast on Central Weather Bureau in TAIWAN, it always shows the higher chance of rain in Hualien compares to other cities in Taiwan.
From our experience, except for the typhoon striking period (tour will be canceled), it only rains lightly in the most of the time.
- In summer time (June-August), it is around 28-35 oC (82-95 oF).
- In winter time (December-February), it is around 8-18 oC (46-64 oF).
