Worst time to visit Spain

July and August in interior Spain are genuinely difficult — by Spaniard standards too

Madrid and Seville regularly hit 35°C through July and August, with Andalusian interior cities (Córdoba, Écija, Jaén) routinely exceeding 40°C. The heat is the kind that locals plan around: many Madrileños leave the city for the coast, small restaurants close for vacation, museum visits become survival exercises in AC-hopping. Spanish heatwaves now break records most years — 2022, 2023, and 2024 each set new highs.

If your dates are locked in July–August: restrict the trip to either the Atlantic north (Bilbao, San Sebastián, Galicia — rarely above 25°C) or the Mediterranean coast and Balearics (still hot but with sea breeze and water access).

The Atlantic north has the opposite problem (Jan–Mar)

Galicia, Bilbao, and Asturias are the wettest part of Spain year-round, and the Jan–March stretch is the wettest, coldest, greyest version. Day-after-day rain for weeks. Manageable for a city break with good cafes and indoor cultural sites, but not what most travelers picture when they imagine Spain.

The exception within winter Spain: Andalusia (Seville, Granada, Córdoba) in December–February is genuinely a smart off-season choice. Mild days (15–18°C), virtually no other tourists, the Alhambra largely to yourself.

Balearic shutdown (November–March)

Ibiza and Mallorca run on a beach-resort calendar. From November through March most beach venues, restaurants, ferries, and tour operators close. Workable for cultural visits to Palma de Mallorca, almost pointless for an Ibiza trip — the clubs (Pacha, Amnesia, Ushuaïa) all close for the off-season.

Crowd peaks worth avoiding

• Mid-July through August — European school holidays converge. Mediterranean coast and Balearics packed, prices peak. Add the heat in interior Spain and this is the perfect storm.
• Semana Santa (Holy Week — late March or April depending on the year) — Andalusia is at peak cultural spectacle, but Seville hotels triple in price and book out 6+ months ahead. Worth doing once with planning, painful as a casual visit.
• Christmas + New Year(December 22 – January 6) — domestic travel surge. Madrid's Puerta del Sol on NYE is a major event but the city is at peak crowd and price.

Heat advisory: real, not just discomfort

Spanish summer heat has caused excess-mortality events in recent years. Even for healthy travelers it's a real planning constraint — siesta hours (14:00–17:00) exist for a reason, plan to be indoors during them. Walking tours, museum visits, and outdoor sightseeing should happen before 11am or after 19:00.

If your dates are locked, route smart

• Jul–Aug: stay on the coast. Atlantic north (Bilbao, San Sebastián, Galicia) or Mediterranean (Costa Brava, Valencia, Mallorca, Ibiza). Skip Madrid + Seville + Granada.
• Jan–Mar: target Andalusia. Skip Atlantic north, skip Balearics (closed). Madrid is workable but cold.
• Nov–Mar: city breaks only — Madrid, Barcelona, Seville. Skip beach destinations.
