One of the great perks of Portugal is its year-round sunshine and nice temperate weather, particularly on the coast and in the south. October is a great time to visit Portugal since you will have fewer crowds than the tourist-packed summer and you will likely have comfortable temperatures throughout the country. There is a lot that you can do this time of year.
Portugal Weather in October
In Lisbon, the average temperature during the day reaches a high of 72 F and at night dips down to around 57 F.
This time of year has higher than usual humidity rates, averaging from 68 to 80 percent, but it's not terribly uncomfortable since the temperatures are mild. You can expect rain for about half of the days of the month. The warmer Portuguese parts are Lisbon and the Algarve, the southernmost coastal cities.
In Lisbon, You can still enjoy sunsets outside at the miradouros (look-out points) but without the hordes of people. The beaches in autumn along the Algarve coast are beautiful. The weather is nice enough for you to grab a book, plunk down on the beach, and enjoy the sun with fewer crowds. You can even take a surfing lesson or a paddle board excursion although the water temps may seem a little cool at 67 F, this is the warmest the water gets during the year.
Porto and the Douro Valley are a little cooler in October than the rest of the country. For example, in Porto, the average temperature is about 10 degrees cooler at 61 F.
But, it is still nice enough to enjoy a glass of Port wine on a rooftop while looking out at Porto's skyline. Or, take a tour of the city's famous Croft Winery, the oldest winery in Porto, for some out-of-this-world port.
If you are visiting the Douro Valley, you will still be able to sit outside at a quinta (wine-producer) and do wine tastings while taking in the views.
What to Pack
In October, it is best to dress in layers. You may leave the morning with a pullover on, then by midday, it may warm up enough that you can remove it. The evenings usually cool down to the point where you will wear it again. You may feel like you want to wear shorts on a few warmer days, but you would be better off in jeans or long pants in case of rain.
Bring a sweater and a light jacket. Comfortable closed-toe shoes, or a pair of sneakers, are the best option for touring Lisbon’s steep paved streets. You may want to pack an umbrella.
