There’s no bad time to visit wineries in Porto & Douro as there is always something on offer that should suit your interests. Celebrations and seasons are accompanied by log fires and sunny dispositions. And there is always the pleasure of discovering an amazing wine, especially to sit back and relax with a stunning Port.
If you like to enjoy the sun and even get a little tan on the beaches, ride a bicycle downtown, travel on foot, and discover the trails, from April to September the weather and temperatures are very good for this kind of activity.
July and August are the hottest months. The microclimate in this wine region means that temperatures in July and August are often in the high 30º C or even hotter so not ideal for walking, especially in the afternoons.
If you want a hands-on experience of the Douro grape harvest, mid to late September is the time to come. You can pick grapes and even crush them by foot in some vineyards. After the harvest, a warm metallic color scheme starts to take over with gold, copper, and bronze tones decorating the slopes.
By late October and into November, the autumn colors are at their best. Winter months are not that harsh with low temperatures, but very wet.
