September is a great time to be in Portugal, and it’s often overlooked. Harvest season begins around this time of year, and a lot of fruits and vegetables come into season. For those who want to experience Portuguese cuisine, this is a particularly wonderful month.

Yes, September in Portugal is in fact often regarded as one of the best times to visit. With the peak season ending, you’ll find that there are fewer crowds. At the same time, the weather is particularly mild and pleasant, with little rain. For many, this is preferred to the scorching heat of the summer months.
Beaches are still inviting, but less crowded, allowing for a more relaxing seaside experience. Additionally, September marks the beginning of the grape harvest season in wine regions like the Douro Valley, offering opportunities for wine tastings and vineyard tours.
With cooler temperatures and fewer crowds, September is the perfect time to rent a bike and pedal your way through charming villages, scenic coastal paths, and historic landmarks.
September in Portugal is a bit of a transition month. You'll find moderate to high tourist traffic as the country moves from the busy summer peak into the shoulder season. While it's not as jam-packed as July and August, you can still expect quite a few fellow travelers, especially at the hotspots like the Belém Tower and Jerónimos Monastery in Lisbon, or the Ribeira district and Dom Luís I Bridge in Porto.
Streets and attractions might be bustling, but it's generally more manageable compared to the height of summer.
Cost-wise, September tends to be easier on the wallet compared to the peak season. While prices for accommodation, transportation, and activities may still be higher than during the off-peak months of winter, they are generally lower than in July and August. Plus, you might stumble upon some promotions or discounts as businesses try to lure in visitors during this shoulder season.
If you’re seeking similar weather conditions but want to dodge the crowds, you might want to consider visiting Portugal in April or early May. You'll still get that glorious weather, but with fewer tourists jostling for space, and potentially a bit easier on your wallet too.
