Portugal suits independent travellers who want city breaks with a coastal feel. You can start in Lisbon, the capital, then head north to Porto, a coastal city. The best months are June, July, August and September, for both the country and Porto. One honest limitation: those best months all fall in summer, so the ideal window is fairly narrow. Outside it, plan with more flexibility. Portugal uses the Euro, and Portuguese is the official language.
June, July, August and September are the best months to visit Portugal. This is the warm, settled part of the year for beach days, city walks and long evenings outdoors. The same months suit both the capital and the coast.
Porto is a coastal city of about 273979 people, so it feels smaller and easier to explore on foot than many European cities. Its best months match the rest of the country: June to September, with August and July at the top.
Lisbon is Portugal's capital and the natural starting point for most trips. You can combine it with Porto on one itinerary, with a city break in the capital and a coastal city in the north.
Portugal covers 92090 km² and has a population of 11424031. That size makes it realistic to see more than one region in a single trip, especially if you drive. Traffic keeps to the right, as in most of Europe.
Portugal uses the Euro, and sockets are type C and F at 230 V, so many European travellers need no adapter. The emergency number is 112, and Portuguese is the official language.

A heavy sandwich from Porto, layered with meats, covered in melted cheese and soaked in a tomato and beer sauce. It usually comes with fries and makes a filling meal.
