Three main climatic zones can be separated, according to geographical situation and orographic conditions:
• The Mediterranean climate, characterized by warm and dry summers. It is dominant in the peninsula, with two varieties: Csa and Csbaccording to the Köppen climate classification. The Csb Zone, with a more extreme climate, hotter in summer and colder in winter, extends to additional areas not typically associated with a Mediterranean climate, such as much of central and northern-central of Spain (e.g. Valladolid, Burgos, León).
• The semiarid climate (Bsh, Bsk), located in the southeastern quarter of the country, especially in the region of Murcia and in the Ebro valley. In contrast with the Mediterranean climate, the dry season extends beyond the summer.
• The oceanic climate (Cfb), located in the northern quarter of the country, especially in the region of Basque Country, Cantabria, Asturias and partly Galicia. In contrary to the Mediterranean climate, winter and summer temperatures are influenced by the ocean, and have no seasonal drought.

Spain is openly multilingual, and the constitution establishes that the nation will protect "all Spaniards and the peoples of Spain in the exercise of human rights, their cultures and traditions, languages and institutions. Spanish (español)—officially recognized in the constitution as Castilian (castellano)—is the official language of the entire country, and it is the right and duty of every Spaniard to know the language. The constitution also establishes that "all other Spanish languages"—that is, all other languages of Spain—will also be official in their respective autonomous communities in accordance to their Statutes, their organic regional legislations, and that the "richness of the distinct linguistic modalities of Spain represents a patrimony which will be the object of special respect and protection.

In 2008 the population of Spain officially reached 46 million people, as recorded by the Padrón municipal (Spain's Municipal Register). Spain's population density, at 91/km² (235/sq mi), is lower than that of most Western European countries and its distribution across the country is very unequal. With the exception of the region surrounding the capital, Madrid, the most populated areas lie around the coast. The population of Spain more than doubled since 1900, when it stood at 18.6 million, principally due to the spectacular demographic boom in the 1960s and early 1970s.

Roman Catholicism has long been the main religion of Spain, and although it no longer has official status by law, in all public schools in Spain students have to choose either a religion or ethics class, and Catholicism is the only religion officially taught. According to an April 2014 study by the Spanish Centre for Sociological Research about 69% of Spaniards self-identify as Catholics, 2% other faith, and about 26% identify with no religion (9.4% of the total are atheists). Most Spaniards do not participate regularly in religious services. This same study shows that of the Spaniards who identify themselves as religious, 59% hardly ever or never go to church, 15% go to church some times a year, 8% some time per month and 14% every Sunday or multiple times per week.

Spanish cuisine consists of a great variety of dishes which stem from differences in geography, culture and climate. It is heavily influenced by seafood available from the waters that surround the country, and reflects the country's deep Mediterranean roots. Spain's extensive history with many cultural influences has led to a unique cuisine. In particular, three main divisions are easily identified: Mediterranean Spain – all such coastal regions, from Catalonia to Andalusia: heavy use of seafood, such as pescaíto frito; several cold soups like gazpacho; and many rice-based dishes like paella from Valencia[181] and arròs negre (arroz negro) from Catalonia.[182] Inner Spain – Castile – hot, thick soups such as the bread and garlic-based Castilian soup, along with substantious stews such as cocido madrileño. Food is traditionally conserved by salting, like Spanish ham, or immersed in olive oil, like Manchego cheese. Atlantic Spain – the whole Northern coast, including Asturian, Basque, Cantabrian and Galician cuisine: vegetable and fish-based stews like caldo gallego and marmitako. Also, the lightly cured lacón ham. The best known cuisine of the northern countries often rely on ocean seafood, like the Basque-style cod, albacore or anchovy or the Galician octopus-based polbo á feira and shellfish dishes.

By Train:
RENFE is the Spanish national rail carrier. Long-distance trains always get in time, but be aware that short-distance trains (called Cercanías) can bear long delays, from ten to twenty minutes, and especially in the Barcelona area, where delays up to 30 minutes are not uncommon. To be safe, always take the train before the one you need. Trains and facilities are clean, services are fast and reliable and prices are on par with those found elsewhere in Western Europe, but there is one catch. Since absolutely all long-distance trains require a reservation (not only the high-speed AVEs!) and are booked out long before, especially in the tourist season, getting around Spain by train is rather difficult and planning ahead is essential. If you turn up at the Madrid-Atocha station expecting to buy a same-day AVE ticket to Barcelona or to the Costas, you'll be disappointed. On the other hand, passengers in Spain ride in style, everyone seated and no people standing in the aisle. This is in sharp contrast with most other European countries, where compulsory reservations are either non-existent or only required for the highest category of trains.
By Bus:
The easiest way to get around most parts of Spain is by bus. Most major routes are point to point, and very high frequency. There is a different operator for each route, but usually just one operator per route. At the bus station, each operator has its own ticket. The staff at any of them is usually happy to tell you who operate which route, however.
By taxi:
All the major cities in Spain are served by taxis, which are a convenient, if somewhat expensive way to get around. That being said, taxis in Spain are more reasonably priced than those in say, the United Kingdom or Japan. Most taxi drivers do not speak English or any other foreign languages, so it would be necessary to have the names and/or addresses of your destinations written in Spanish to show your taxi driver. Likewise, get your hotel's business card to show your taxi driver in case you get lost.
