Douro Valley is at its best for wine/vineyards in May to June and September to October. Good but not prime in July and August. Crowds peak in July and bottom out in December.

August, then July and September — busy May through October, with September the harvest rather than the peak
Summer heat on steep terraces. The river cruises are mostly adults-only — Viking takes no under-18s — so they are the least child-friendly way to see it.

Kept out of the score on purpose. Averaging a rare catastrophe into a monthly number would tell you something false; the warning is the honest form.
The terraces are a UNESCO landscape and most quintas will point you at a path. Gentle walking with a view rather than a trekking destination.
