A trip to Portugal in August is particularly enjoyable if your five P’s are sorted: a plump purse, patience, people-loving spirit, pre-planning, and pre-booking your trip. You will need these travel essentials to fight the legendary mad tourist rush of August head-on. So, if you are a seasoned traveler, now is the time to ditch the tourist trail and go off-grid. Soaring sun and absolute dry days mean it is time to hit the beach. Foray a little deep to find an equally picturesque alternative to the famous beaches of the Algarve in the calmer Southwest Alentejo or Centro region. Substitute watersports with an adventurous outing in Peneda-Gerês National Park. Its scenic waterfalls, lush forests, and fast-flowing rivers offer you the chance to canoe, raft or simply hike.

By August, the busy summer season is already on a romp. That being said, there are plenty of advantages to traveling to Portugal in August. Here are a few of them:

  • Summer bonanza: August is a month with virtually no rainfall. A dry month also means wet places like Porto and the Douro Valley can be visited without rain spoiling your sightseeing. Long summer days also affect the opening hours of museums and other attractions that close late, giving you more hours to pack your day with a lot of activities or enjoy one activity at a leisurely pace.
  • Swimming season: The North Atlantic is otherwise deemed too cool to swim during the rest of the year, but with the arrival of August, it heats up to a comfy temperature. The warmest waters are found off the east coast of the Algarve. As you travel west, the water starts to cool down. The archipelagos of Azores and Madeira are also great for swimming in high summer.
  • Festivals: August is abuzz with all kinds of summer fairs and festivals. Venture to the quaint, fortified town of Viseu which is located on the Portugal-Spanish border, where they hold a 49-day long festival called Feira de São Mateus in honor of Saint Matthew. Besides the month-long procession, you can enjoy their fairground rides, stalls selling handicrafts and local eateries, folk music, and fireworks display. Foodies can troop to one of the biggest fishing ports of the Algarve, Olhão, to sample some scrumptious fresh seafood cooked in various local ways at their Festival do Marisco. Chomp on some grilled goodies or tuck in some stews as you enjoy the party atmosphere of the festival.

Where to go and what to do

Indulge in the hustle and bustle of the packed cities or opt for quieter areas of Portugal in August.

Instead of jostling with crowds in larger cities, steal some solitude walking through the maze-like alleys as you explore Braga and its medieval buildings, monasteries, and baroque gardens. Discovering north Portugal should top your priority list in August as all the crowds congregate in beach towns leaving you to discover Porto freely. If you are visiting Madeira in the last week of August, attending the Madeira Wine Harvest Festival in Funchal is a must. Do booth-hopping and sample some incredible wine from this region.

For a much less busy option to the capital city, head to Camara de Lobos. If you wish to visit Algarve is where you want to go, choose calmer beach towns like Alvor and Carvoeiro than hectic places like Albufeira and Lagos. You can rent a car and go for long drives in these calm and beautiful towns of Portugal. The Portuguese love their music and dance and as summer heats up, so does the party scene. The Algarve erupts with lively nightlife venues in popular places like Faro, Lagos, Vilamoura, and Albufeira. Upscale resorts, luxury hotels, romantic bars, and beach clubs — there is a party spot to suit every mood. Clubs here often open at around 11:00 pm and remain so till 7:00 am.
