What is the best month to visit the Douro?

It depends on what you are after: May and June for mild weather, July to September for heat and dry spells, winter for quiet.

Summer is hot and dry. At Vila Real, a station higher than the valley floor, there are on average 13 to 14 days at 30 °C or above in July and in August.

Mostly from autumn to spring: December is the wettest month at the Vila Real station.

Can you take a day trip in winter?
