What you gain in September
- ↑Douro Valley vintage harvest (September–October) is the most spectacular time to visit the wine country: the terraced hillsides are golden and red, the quintas are working at full capacity, and harvest tastings are available at wineries that close to casual visitors in summer
- ↑Weather is still excellent — 25°C, 8 sunshine hours, and only 35mm of rain — while August's crowds have begun to thin meaningfully after the school return
- ↑The restaurants of Bonfim and Cedofeita are at their best: the autumn menus appear, the chefs are rested from the tourist onslaught, and bookings are achievable on shorter notice
What you sacrifice
- ↓Prices have not fully recovered from peak — September is still moderate-to-expensive; the dramatic discounts don't arrive until October
- ↓The first autumn rains can appear in late September; not reliably dry through the whole month
- ↓The Douro Valley harvest tours are extremely popular — booking winery visits well in advance is essential for September
