Spain stretches from the Atlantic to the Mediterranean, from North African latitudes to the green valleys of the Cantabrian coast. That means timing matters. A perfect week in Seville might be miserable in San Sebastián, and vice versa. Here’s how to plan your trip based on where you’re actually going.
Andalusia: Spring and Fall, Skip August
Seville, Córdoba, and Granada are stunning from mid-March through May and again from late September through November. Temperatures sit comfortably in the 70s and low 80s, orange blossoms perfume the air in spring, and you can walk the streets without melting.
Summer in Andalusia is brutal. Córdoba regularly hits 105°F in July and August, and locals flee to the coast. If you must visit in summer, plan museum visits and indoor sightseeing for midday, and save evening strolls for after 9 p.m. when the heat finally breaks.
Winter is underrated here. December through February brings mild days in the 60s, fewer crowds at the Alhambra and Mezquita, and lower hotel rates. Pack a jacket for evenings, but you’ll likely eat lunch outdoors in January sunshine.
Barcelona and the Mediterranean Coast: May, June, and September
Barcelona shines in late spring and early fall. May and June offer long days, warm beach weather, and the city before the summer crush. September is even better—the Mediterranean stays warm through October, but cruise ship crowds thin out after Labor Day.
July and August mean peak prices, packed beaches, and many locals on vacation. Some beloved neighborhood restaurants in Gràcia and Sant Antoni close for two weeks in August. The trade-off: festivals, outdoor cinema, and beach clubs in full swing.
Winter along the Costa Brava and Costa del Sol stays mild. Málaga averages 60°F in January, and you’ll find restaurant tables and museum breathing room. Just don’t expect to swim—the sea gets chilly from November through April.
The Basque Country and Northern Spain: Late Spring Through Early Fall
San Sebastián, Bilbao, and the green coast have a completely different climate. This is Atlantic Spain—it rains. A lot. Locals joke that if you can see the mountains, it’s about to rain; if you can’t see them, it’s already raining.
June through September offers your best shot at dry weather and temperatures in the 70s. July and August bring the warmest water for swimming at La Concha beach, though it never gets truly warm by Mediterranean standards.
Avoid November through March unless you love moody skies and wet cobblestones. That said, San Sebastián’s pintxos bars stay excellent year-round, and the Guggenheim Bilbao is an indoor masterpiece. Just pack a good rain jacket and waterproof shoes.
Madrid and Central Spain: Spring and Fall, Winter for Museums
Madrid sits on a high plateau—it’s hot in summer, cold in winter, and glorious in between. April through June and September through October deliver perfect sightseeing weather. You can walk from the Prado to Retiro Park to Gran Vía without breaking a sweat.
Summer in Madrid is manageable if you adjust your schedule. Museums and air-conditioned tapas bars from 2 to 5 p.m., then the city comes alive after 8 p.m. Madrileños eat dinner at 10 p.m. in summer for good reason—it’s still 85°F at sunset in July.
Winter brings crisp, sunny days and freezing nights. January averages in the low 40s, but it’s a dry cold. The Prado, Reina Sofía, and Thyssen museums are never crowded on weekday mornings from November through February. Evening chocolate con churros at San Ginés tastes better when it’s 35°F outside.
The Islands: It Depends Which One
The Balearics—Mallorca, Menorca, and Ibiza—follow Mediterranean patterns. May, June, and September are ideal. July and August mean crowds and high prices, especially in Ibiza. Winter is quiet, many hotels close, but Palma de Mallorca makes a lovely mild-weather city break from November through March.
The Canary Islands off the African coast stay warm year-round. Tenerife and Gran Canaria average 70°F even in January, making them Europe’s winter beach escape. Summer is actually less ideal here—June through August can be windy, and European package tourists pack the resorts. Go in winter or shoulder season instead.
Festival Timing
Some dates override weather logic. Semana Santa (Holy Week) in Seville is unmissable but falls in March or April when weather can be unpredictable. The Feria de Abril follows two weeks later. Las Fallas in Valencia burns brightest in mid-March. San Fermín in Pamplona runs July 6–14, right in summer heat. Book far ahead for any of these—hotels fill up a year in advance.
La Tomatina in Buñol happens the last Wednesday in August, when temperatures hit 90°F. You’ll be covered in tomatoes anyway, so the heat barely matters.
General Rules
Book ahead for Easter week, all of August, and any major festival. Expect higher prices and crowds. Shoulder seasons—April to mid-June and September to October—offer the best combination of weather, value, and availability across most of Spain. Winter rewards museum lovers and city explorers who don’t mind a jacket.
And remember: Spain does summer differently. Shops close from 2 to 5 p.m., dinner starts at 9 or 10 p.m., and the whole country slows down in August. Plan accordingly.
