September is hands-down one of the loveliest months to visit Portugal. The weather is still fine (but not as hot as August), the ocean has had all summer to warm up, and the crowds are finally starting to thin. And the first whisper of fall is bringing seasonal color and new wine to regions like the Douro as the grape harvest gets underway.
The allure of Portugal in September is undeniable, as the scorching heat of summer begins to mellow, ushering in a season of pleasant temperatures, fewer crowds, and a tapestry of cultural experiences. The intense summer throngs have dissipated, making way for a more relaxed and immersive exploration of this captivating country.
**Weather in September: A Transition to Delightful Days**
The warm weather continues its reign well into September, yet the fiery days characteristic of high summer are receding, taking with them the overwhelming presence of tourist crowds. This creates a harmonious balance, offering sunshine without the intensity, and space to breathe and truly appreciate the surroundings.
In **Porto**, located in the northern reaches of Portugal, you can anticipate delightful highs hovering around 75°F (24°C). While the weather remains largely agreeable, it’s worth noting that rainfall begins to make a gradual return, with the possibility of up to five wet days scattered throughout the month. Packing a light rain jacket or umbrella is advisable to fully prepare for any potential showers.
Further south, in both **Lisbon** and the **Algarve**, temperatures tend to be slightly warmer, reaching upwards of 79°F (26°C). This creates an ideal climate for various activities, from leisurely exploration of historic sites and charming neighborhoods to simply unwinding on the pristine beaches that grace the coastline. While the days remain balmy and inviting, it’s important to remember that evenings tend to become cooler as the month progresses. Packing a sweater or light jacket will ensure comfort and allow you to fully enjoy the evenings, whether you’re dining outdoors or taking a stroll along the waterfront.
**Crowds and Costs: The Advantages of Shoulder Season**
With school vacations across Europe drawing to a close in early September, the cost of flights and accommodations begins to drop noticeably as the shoulder season takes hold. This presents a fantastic opportunity to secure advantageous deals, particularly in coastal resorts. Visiting in the latter part of September often yields even greater savings, as the crowds continue to thin out, creating an even more tranquil atmosphere.
While the cities maintain a vibrant energy and continue to welcome a steady stream of travelers, the intensity of the peak summer months diminishes significantly. The noticeable reduction in crowds translates to a more enjoyable experience when visiting popular attractions. Shorter lines and a more relaxed pace allow for a deeper engagement with the historical and cultural treasures that Portugal has to offer.
**Where to Go: Exploring Portugal’s Diverse Regions**
If your heart desires a final opportunity to bask in the lingering rays of summer and take a refreshing dip in the Atlantic Ocean, September presents your last chance before the temperatures begin to decline and the autumn rains gradually arrive.
The **Algarve** remains exceptionally hot and dry, with the summer season still in full swing. While the resorts are vibrant and lively, they are significantly less crowded compared to the bustling atmosphere of August. This offers a more relaxed beach experience and easier access to restaurants and other amenities. Furthermore, the emergence of the first proper swells makes September an excellent month for surfing enthusiasts to visit west-coast resorts such as **Peniche** and **Ericeira**.
In major cities like **Lisbon** and **Porto**, the intensity of the summer crowds begins to subside, particularly towards the end of the month. The slight dip in temperature and the thinning of crowds provide a welcome respite, making it an ideal time to explore these vibrant urban centers at a more leisurely pace.
Venture beyond the cities and you’ll discover rural regions that are truly coming into their own during September. The breathtaking **Douro Valley**, stretching eastward from **Porto**, showcases a mesmerizing tapestry of autumnal colors. Farm stays offer a unique opportunity to immerse yourself in the region’s agricultural heritage, with long country walks providing stunning views of the vine-draped landscape. Further south, the **Alentejo** region also embraces the arrival of fall, offering equally captivating scenery and opportunities for relaxation and exploration.
**What to Do: Immersive Experiences Await**
September stands out as an ideal month for embarking on a city break. Plazas and street cafes remain vibrant and full of life, inviting you to soak in the atmosphere and enjoy the local culture. The days are still long, and the slightly cooler temperatures make exploring on foot a far more pleasant experience. Summer opening hours are still in effect at major attractions and UNESCO World Heritage sites, while visitor numbers gradually decrease, creating a more intimate and engaging experience.
The stunningly beautiful **Douro Valley**, with its steeply terraced vineyards, reaches its photogenic peak during this time. The hillsides, forests, and vineyards are ablaze with fall colors, creating a breathtaking spectacle of russet and gold hues. The region’s seasonal flavors and new wines are showcased on menus, adding another layer of sensory delight. Spending a few nights at a farm stay allows you to fully immerse yourself in the Douro Valley experience, with opportunities for walks, guided tours, and wine tastings. Grapes hang heavy on the vines, and at some *quintas* (wineries) you may even have the opportunity to participate in the grape harvest.
The **Alentejo** region also offers a delightful experience in September. Mists rise to reveal a tapestry of vibrantly colored woods, vines, and olive groves, creating a picturesque landscape that is perfect for leisurely walking or cycling. Food enthusiasts will be delighted by the regional menus, which feature game dishes, wild mushrooms, and chestnuts, all reflecting the flavors of the season.
**September Events: A Celebration of Culture and Tradition**
**Nossa Senhora da Nazaré**: The Estremadura coastal resort of **Nazaré** pays tribute to Our Lady with a pilgrimage, a mass in its sanctuary, and a religious parade on September 8. But the festivities don’t end there. The celebration continues with parades, parties, folk dancing, bullfighting, and fairs until late September.
**Feiras Novas**: The charming riverside town of **Ponte de Lima** in the Minho region pulls out all the stops for this festival in early September. The festival, which has been going strong since 1125, shows no signs of slowing down. For six days, the town is transformed into one giant street party, complete with folk music, dancing, feasting fairs, and fireworks.
**Festa de Nossa Senhora dos Remédios**: If you happen to be touring the **Douro** wine country in early September, try to time your trip to coincide with this festival in **Lamego** (thousands do). In addition to religious pilgrimages, processions, torchlit parades, and flower battles, you’ll find exhibitions, concerts, parties, dancing, and all-around merrymaking.
