Portugal in May: A Sneak-Peak Into Summer
Head for Portugal in May if you want to steal some summer fun even before the season begins. Days are longer during this time of year (the country receives more than twelve hours of sunshine) and the weather is consistently dry. And though the seawater is yet to reach swimming temperatures, the land is befitting for some leisurely beach time.
Weather conditions across mainland Portugal in May are perfect for sightseeing in cities like Porto, Lisbon, and Coimbra, or for hiking through the backcountry in Serra da Estrela and Peneda-Gerês National Park. The weather across Portugal’s islands also improves significantly as winter recedes, with the Azores finally seeing some dry days. Spend your days swimming in warm waters or relaxing in one of its natural lava rock pools.

Why Visit Portugal in May
In addition to extremely kind weather gods, a trip to Portugal in May packs plenty of other plus points. We have listed a few of them below.
- Better rates: Get a bang for your buck with a budget holiday before the summer rush commences. May is when almost all properties open shop after a winter break and offer enticing deals to attract customers as footfall is low and it is still off-season. Airfares are also economical, and car rentals are affordable as well.
- Lesser crowd: Barring the Whitsun school break that normally takes place in the last week of May, the rest of the month hardly sees any tourist horde. Enjoy a laid-back and deep exploration of any destination you pick as attractions are open till late as per their summer-opening schedule.
- Festivals: From a spectacular display of flowers in Festa da Flor Madeira in Funchal to Feira do Livro de Lisboa in Lisbon where you can satiate the bookworm in you, from jamming at Somersby Out Jazz to Rally de Portugal for racing fanatics, Portugal in May offers a dazzling array of celebrations. And for a glimpse of something spiritual, join the candlelight procession of Our Lady of the Rosary on May 13. This celebration takes place in the tiny village of Fatima.
- Outdoor activities: Walk for miles without breaking a sweat during your trip to Portugal in May. Exploring its quaint cities on walking tours and hiking through its coastal trails or mountain routes are some of the activities worth enjoying during this month. The sea might be cold for swimming, but you can still enjoy the water if you like surfing.
Where to go and what to do
If the erratic rains of April made you skeptical about visiting the Douro Valley, the drier and sunnier May will invite you back. Take in lush, terraced vineyards and double the fun with enjoyable boat tours and wine tastings in the mild May weather. If you are thinking of touring the Algarve, now is also the busiest time for golfing down in the region. Along with teeing off on a world-class golf course, you can also pile up on some quality beach time in the Algarve's stunning cliff-backed beaches or go on a coastal hike to enjoy an intimate nature workout. Explore the archipelago of Azores as it is the window of calm between the stormy month of March and the tourist-heavy June. Cherish its landscape bursting with wildflowers, do some whale-watching and, for the ultimate thrill, risk it all to run with the bulls at Tourada a Corda.
Shrugging off its winter hiatus, the whole country opens up to welcome travelers in May. Portugal’s weather in May is mild and the number of travelers is still low, which means that you can do plenty at your own pace and that too at an attractive budget.
