September trade-offs
- ↓248mm of rain — typhoon season is not over; September sees some of the year's most powerful storms
- ↓Still hot and humid throughout most of the month; the autumn window doesn't open until late September at the earliest
- ↓Day trips to Jiufen and Yangmingshan remain unreliable with typhoon and heavy rain risk
November trade-offs
- ↓Sunshine hours drop slightly to 5 per day as the season progresses; cloud cover increases toward December
- ↓Some rain remains at 87mm — the same as January, so occasional grey days are part of the deal
- ↓Night temperatures drop to 17°C by month's end — evenings require a layer, especially in the mountains
