Portugal's travel costs are significantly shaped by its distinct seasons. High season, spanning June, July, and August, brings the warmest weather and peak tourist activity, naturally leading to higher prices for accommodation, flights, and popular attractions. Expect bustling cities and crowded beaches during these months, and plan to book well in advance for the best rates.
Conversely, the low season from November through March offers a quieter, more intimate experience with substantially reduced prices. While the weather is milder, and some coastal areas might be less vibrant, it's an ideal time for budget-conscious travelers to explore cities like Lisbon and Porto, enjoy cultural sites, and find excellent deals on lodging. Availability is generally high, allowing for more flexibility.
The shoulder seasons in spring (April-May) and autumn (September-October) strike a perfect balance. You'll enjoy pleasant weather, fewer crowds than summer, and moderate prices across the board. This period provides an excellent opportunity to experience Portugal's natural beauty and urban charm without the peak season rush or the lower season's cooler temperatures, making it a favorite for many visitors.
