Porto is warmest in July and August when the temperature is around 35 or 40 degrees. Summer also has low humidity, cooling breezes, and little rain. Mid-September is the beginning of the rainy season, and the amount of rainfall peaks in December which has an average rainfall of 45cm (18 inches). The rain continues into May, although it eases off in March. Winters are mild.
The public transport system in Porto is cheap and easy, but many tourists enjoy walking or biking, especially in the old section of town, where the sights are close together. Don’t worry about getting lost in the narrow streets, just ask a resident to point you in the right direction. Buses, trams and the metro will get you around the city quickly, and the funiculars can take you from the Ribeira to the city’s centre. Local trains can take you to the outer edges of the city and to the beaches. Avoid travelling during rush hour, as public transport can get very crowded. Look for discount or multiple-trip tickets such as the Passe Turistico, bulhete diario (day pass) and the rechargeable Andante Card to save money. You can hail, call or pick up a taxi from a stand 24 hours a day.
Driving can be very difficult, thanks to heavy traffic and a maze of one-way streets. With all the transport system options in Porto, renting a car isn’t worth the hassle.
Porto is the capital of Port, the country’s most famous wine region. A visit to the Port lodges in Vila Nova da Gaia, where the wines are aged, is a must. Vila Nova da Gaialies opposite Oporto, across the river Douro. The city is also known for the “Barcos Rabelos”, the flat-bottomed boats that used to ship the Port from the vineyards. The boats take part in a thrilling race (in June each year), part of the Festival de Sao Joao do Porto (feast of St. John).
The funicular railway that runs up the hill from the riverside to the Praca da Batalha is a great way to see the city.
Porto’s historic center is a Unesco World Heritage site. The Praca da Ribeira is a popular meeting place. Ribeira’s Quay is the original port. The area is charming with cobbled streets, brightly painted houses, small shops, cafes and restaurants. A walk along the Ribeira Quay leads to the Dom Luis Bridge, which links Porto with Vila Nova da Gaia. The bridge was built in the 1880s by Teophile Seyrig, a Belgian engineer who studied with Eiffel. The bridge with its iron structure owes much to the Eiffel Tower.
Porto Cathedral was started in the 13th century, added to at the end of the 14th (Gothic cloister) and 16th centuries (Chapel of St. Vincent) and the main chapel was added in the 17th century. In 1736, Nicolau Nasoni, the baroque Italian architect added the north facade. The cathedral is located on the hill above the grand Sao Bento train station. The views from the cathedral of the old quarter are beautiful.
The Sao Francisco Church is one of Porto’s last remaining medieval buildings, and the only Gothic church in the city.
