Portugal in August welcomes peak summertime. The country is alive with festivals, cultural events and, of course, sunshine, sea, and sand galore. It’s the month when both locals and international visitors flock to the coast, the countryside, and the cities to make the most of the long days and warm evenings, and the atmosphere is simply buzzing.
In this blog, we’ll explore what makes Portugal in August so special – from the weather in Portugal in August to the best places to go, and the events and activities not to be missed.
August Weather in Portugal
August is one of the sunniest and driest months of the year in Portugal, offering consistently warm days and clear skies—ideal conditions for outdoor exploration and coastal escapes. Travellers can expect long daylight hours, minimal rainfall, and high UV levels across the country. The Algarve in the south is particularly hot and dry, making it perfect for family beach holidays, while regions like the Douro Valley are similarly sun-drenched, though with lower humidity than the coast. In the north, cities such as Porto remain warm but more moderate, often benefitting from cooling Atlantic breezes. These conditions are also excellent for hiking early in the day or enjoying warm evenings at open-air festivals and cultural events.
Temperature in Portugal in August
The temperature in Portugal during August varies by region but remains reliably warm throughout the country. Here’s a closer look at what to expect in different areas:
- Lisbon: 28–32°C during the day, cooling to 18–20°C at night
- Algarve: 30–36°C in the daytime, with warm evenings around 20–22°C

Best Destinations in Portugal in August
Planning a coastal escape? Or perhaps you’re more of an island adventurer? Whatever you have planned, Portugal in August offers something for every kind of traveller.
The Algarve is a summer favourite, with golden beaches, warm seas, and lively towns like Albufeira, Lagos, and Vilamoura. Water sports, beach bars, and family-friendly resorts make it ideal for sunny getaways.
Lisbon remains lively in August, buzzing with events and visitors. Ride the tram through Alfama, enjoy views from hilltop miradouros, and take day trips to Sintra or the beaches of Cascais and Costa da Caparica.
Cooler than the south, Porto is perfect for riverside strolls, Port wine tasting, and exploring the Douro Valley by boat or car. The vineyard-covered hills are especially stunning in the summer sun.
The Azores are ideal for cooler climes and outdoor pursuits. August is peak hiking season across islands like São Miguel and Pico. Get ready for whale watching, crater lakes, and dramatic coastlines.
Madeira in August is warm, green, and festive. Explore its cliffs and gardens, swim in natural pools, and enjoy events like the Madeira Wine Festival while soaking in the island’s laid-back charm.
Activities and Events in Portugal in August
August in Portugal is the height of summer, and with such glorious weather, the country becomes a playground for outdoor enthusiasts, culture lovers, and festivalgoers.
Activities
For those keen to explore Portugal’s natural beauty, this is an excellent time for hiking. Coastal trails like the Percurso dos Sete Vales Suspensos (Seven Hanging Valleys Trail) in the Algarve offer stunning views of limestone cliffs, turquoise coves, and hidden beaches. Early mornings are best to beat the heat and crowds, and the reward is a dramatic seascape unlike anywhere else in Europe.
Further north, the Sintra-Cascais Natural Park is ideal for shaded forest walks and panoramic vistas over the Atlantic. This region combines rugged trails with heritage sites like the Pena Palace and Moorish Castle, making it perfect for those who want a blend of nature and history.
Of course, no trip to Portugal in August would be complete without time spent on the coast. The beaches are in their prime this month, with warm water temperatures and long, sunny days. Travellers are spoiled for choice with plenty of beaches around Lisbon, including the entire coastline as far as the Algarve.
Beyond the beach, towns like Setúbal, Cascais, and Comporta are well worth a visit. Cascais is a charming seaside escape just outside Lisbon, filled with boutique shops, seafood restaurants, and scenic coastal paths. Setúbal offers a more authentic experience with excellent fish markets and access to the nearby Sado Estuary, where you can spot dolphins. Comporta, with its laid-back vibe and stylish beach bars, attracts a fashionable crowd looking for peace and privacy.
Events
As for cultural events, Portugal’s summer calendar is packed with festivals. Neopop Festival (7-9 August) in Viana do Castelo is a highlight for fans of electronic music, offering high-energy sets from world-renowned DJs in a scenic riverside location. Indie music lovers should head to the Vodafone Paredes de Coura Festival(13-16 August), set against the picturesque Coura River, while the Vilar de Mouros Festival—Portugal’s oldest rock event—continues to charm audiences with its rich history and loyal following (21-23 August).
For something a little more traditional, from 30 July to 10 August Viagem Medieval in Santa Maria da Feira transforms the town into a full medieval fair, complete with jousting, crafts, and period costumes. In Viana do Castelo, the Romaria de Nossa Senhora da Agonia (12-20 August) is one of the country’s most striking celebrations, showcasing colourful processions, traditional dress, and gold filigree jewellery.
On the islands, there’s just as much going on. In Madeira, the Madeira Wine Festival kicks off on 24 August, honouring the island’s centuries-old winemaking tradition with tastings, grape-stomping demonstrations, and cultural displays. The Azores, too, host events like Maré de Agosto (21-23 August) on Santa Maria Island, a relaxed music festival by the sea, and Azores Burning Summer (30-31 August) on São Miguel, which merges art, music, and environmental awareness in a beautiful beachside setting.
