Spring means the average daytime temps throughout the country will be around 62°F/16°C, but at night temps can still dip into the 40s. Of course, on the Mediterranean coast and the further south you go, the heat will rise, which means the sun will be out and you can start doing some sunbathing on Spain's beautiful beaches and its offshore islands. Alas, in most places in Spain the water will still be too chilly for swimming.
The region of Andalusia, particularly, will see temps spike and it averages a glorious 75°F23°C while not dipping below the 50s (Fahrenheit) at night. It's the perfect weather to enjoy some outdoor walking tours of historic Andalusian cities like Málaga, Seville, and Cádiz.
Crowds & Costs
During the big festival in Andalusia expect Seville to swell with visitors (more on this below). Also, now that the beaches are starting to open you can expect more people to show up on the Mediterranean coast and on the islands to enjoy some sunbathing. Even so, crowds won't be nearly as oppressive as they will be in the dog days of summer. You'll still be able to take advantage of the shoulder-season airfare and hotel prices, which can be hundreds of dollars less than they typically are in the high season.
Where to Go
Spring in Spain? There's one place you can't miss: Seville. Travel to the southern Andalusia region, and in its historic capital city, you'll find a festival that draws over a million visitors each year for a week of food, fun, and flamenco. Moreover, the spring weather is perfect, as it's before the summer months when Andalusia becomes oppressively hot.
Now that the sun is out in full swing there are some other areas you won't want to miss. These include beach resort cities and islands like Marbella, Ibiza, Menorca, Mallorca, Alicante, Málaga, and elsewhere. This would be the perfect time to plan a road trip along Spain's Costa del Sol with the top down and the wind in your hair.

What to Do
Aside from the big parties, April is a perfect month to enjoy the newly sunny weather. Even if a road trip isn't part of your vacation plans, there are other ways to enjoy Spain to the fullest. Consider a combined culture/foodie tour of the country. You could visit the most famous museums in Spain, such as the Prado in Madrid, Guggenheim in Bilbao, on the northern Atlantic coast, and MACBA (Museu d'Art Contemporani de Barcelona) in Barcelona.
After marveling at the works of master painters, you'd then enjoy the distinct cuisine in each of these regions. In Madrid you can take a walking tour of food markets and tapas bars; in San Sebastian, near Bilbao, you can sample the pintxos (small plates) for which the city is deservedly famous; and in Barcelona you can preface your wild nights out in the Gothic Quarter with a quick bite in a moody tapas bar.
And if you're religious or just love spectacle and celebration, try to be in Spain in early April for Semana Santa, or Holy Week (more on this below).
Events in April
Semana Santa. In early April the nation celebrates their Holy Week. Rather than a rabbit hiding eggs, however, Spain remembers the Passion of Christ through a series of processions in cities and towns throughout the country. If you're looking for the grandest festivities, head to the northern Castilla-Leon region and the city of Salamanca, or Andalusia and cities like Seville and Málaga. Before booking travel plans check exact dates of Semana Santa, because it changes each year along with the liturgical calendar.
Feria de Abril. The biggest party in Andalusia kicks off in Seville two weeks after Semana Santa. Held at the giant fairground of Los Remedios, located in the southwest of the city, it features parades and plenty of dancing, as this is the birthplace of Flamenco music. Moreover, partaking in this festival is a great opportunity to dance to Sevillanas, songs of a certain genre of folk music. The festivities last a week, there are daily bullfights plus eating, drinking, and carousing that lasts until the wee hours of the morning.
