The Best Time to Visit Spain (Month-by-Month, 2026)

Spain is bigger and more varied than most first-timers expect, and the three zones rarely agree on the weather.

The central meseta (Madrid, Toledo, Castile): a high inland plateau with a continental climate, which is the polite way of saying brutal extremes. Summers are dry and fierce, with Madrid pushing 35-40°C in July and August and the open squares offering nowhere to hide. Winters are cold and clear, 8-14°C by day with frosty nights. The shoulders, April-June and September-October, are when the meseta is genuinely lovely.

The green north (Basque Country, Galicia, Asturias, Cantabria): a cool, wet, Atlantic climate that looks more like Ireland than the Costa del Sol. Summers are mild at 22-26°C and the landscape stays green all year, which is exactly why this is where Spaniards themselves head in August. The trade-off is rain, possible in any month.

The Mediterranean south and east (Andalucía, Valencia, Barcelona, the islands): hot, dry summers and mild winters. Seville and Córdoba are the heat capitals, regularly 40°C-plus in midsummer, while the coast stays a touch kinder. Winters are gentle, Andalucía a sunny 12-18°C, the Canaries 20-24°C and warm enough for a winter beach.

The practical upshot: pick the south and centre for spring and autumn, retreat to the green north or the islands if you're stuck travelling in high summer, and don't write off winter for Andalucía and the Canaries.

January: Madrid 10°C, Seville 16°C, Barcelona 13°C. Off-peak and cheap. Andalucía sunny and mild, the Canaries 20-24°C. Alhambra tickets finally easy to grab on the day.

February: Madrid 13°C, Seville 18°C, Barcelona 14°C. Still quiet. Cádiz Carnival lights up the south in late February. Flights at yearly lows.

March: Madrid 16°C, Seville 21°C, Barcelona 16°C. Shoulder begins. Valencia's Las Fallas (mid-March) fills the city with giant effigies and fireworks; book ahead. Easter is early in 2026 (April 5).

April: Madrid 19°C, Seville 24°C, Barcelona 19°C. Excellent. Semana Santa processions (Holy Week, late March into early April) are at their most dramatic in Seville and Málaga — spectacular but pricey and crowded.

May: Madrid 24°C, Seville 28°C, Barcelona 21°C. The finest single month on paper. Córdoba's patios festival runs early in the month and Seville's Feria de Abril spills in from late April (two weeks after the late 2026 Easter), everything's open, flights pre-peak, Andalucía a kindly 25-28°C.

June: Madrid 30°C, Seville 33°C, Barcelona 25°C. Warm and busy, the south heating up. Still excellent for the north and the coast; the meseta starting to bite.

July: Madrid 35°C, Seville 40°C, Barcelona 28°C. Peak heat and peak prices in the south. Pamplona's San Fermín (early July) is the bull-running spectacle. Sightsee at 7am and 7pm with a long siesta gap.

August: Madrid 35°C, Seville 41°C, Barcelona 29°C. Brutal inland; locals decamp to the coast and the north. La Tomatina (last Wednesday) near Valencia. Head north or to the Balearics if this is your window.

September: Madrid 30°C, Seville 35°C, Barcelona 26°C. Second sweet spot. Heat easing, post-summer hotel rates sliding 15-25% off their August high.

October: Madrid 22°C, Seville 28°C, Barcelona 22°C. Lovely shoulder. Warm enough for the Alhambra gardens, cool enough to walk the cities.

November: Madrid 14°C, Seville 21°C, Barcelona 17°C. Quiet and cheap, south still pleasant.

December: Madrid 10°C, Seville 17°C, Barcelona 14°C. Cool and festive. Christmas lights in Madrid and Barcelona; the Canaries hold 20-24°C — a warm-weather break in the northern winter, or a mild off-season swap if you're coming from the southern-hemisphere summer.

The standard 10-day Spain tour hangs off the AVE high-speed spine: Madrid and Toledo, down to Córdoba and Seville, across to Granada for the Alhambra, then north to Barcelona. For this specific route, May and September are decisively better than anything else.

May is probably the finest single month for the loop. Andalucía sits at a kindly 25-28°C, Madrid and Barcelona at a comfortable 22-26°C, and the Alhambra gardens and Seville's open-air sights are a pleasure rather than an ordeal. Everything's open, the flights haven't hit summer peak, and the festival calendar is generous — Seville's Feria de Abril and Córdoba's patios festival both fall early in the month.

September mirrors May on weather and adds a pricing bonus: post-summer hotel rates slide 15-25% off their August high, the crowds at the Alhambra and Sagrada Família thin out, and Andalucía has cooled from its midsummer extreme back to the high twenties. Tour pricing drops back from peak through the month.

April and October are the honest backups. April brings Semana Santa, which is a spectacle in Seville and Málaga but spikes prices and crowds, so target the weeks either side of Holy Week. October cools the meseta nicely but shortens the daylight.

Avoid for this route specifically: mid-July through August. Seville and Córdoba hit 40-42°C, the open-air sections of the Alhambra turn genuinely unpleasant, and you end up sightseeing in two short windows around a long midday siesta. The classic loop leans heavily on the hot south, which is exactly where high summer hurts most.

Spain's festivals are some of the best in Europe, and they can make or break your timing, both for the spectacle and for the prices and crowds they pull.

Semana Santa (Holy Week, late March into early April; Easter is April 5 in 2026) is the big one. Hooded processions carry ornate floats through the streets night after night, and Seville and Málaga stage it at full intensity. It's genuinely moving, but hotels in the processional cities fill months ahead and prices spike 25-40%. If you want the classic loop without the surge, target the weeks either side rather than Holy Week itself.

Las Fallas (Valencia, mid-March, climaxing March 19) fills the city with enormous satirical effigies that are paraded for a week, then burned in a single spectacular night of fireworks. Book Valencia accommodation well ahead.

Feria de Abril (Seville, roughly two weeks after Easter) is the city in full flamenco-and-horses mode, with a fairground of casetas running through the night. It's a wonderful time to be in Seville and a terrible time to find a cheap room.

La Tomatina (Buñol, near Valencia, last Wednesday of August) is the famous tomato-throwing free-for-all — a single morning, ticketed, and a fun bolt-on if you're already in the east in late August.

San Fermín (Pamplona, early July) is the running of the bulls, a week-long northern festival that draws huge crowds. Plan around these if they're a draw, or steer clear of the relevant cities if they're not.

Spain flight pricing has two distinct patterns depending on where you fly from.

From Europe: Iberia is the flag carrier, but from most European origins you'll be on Ryanair, Vueling, easyJet, British Airways or Aer Lingus. Return fares from Dublin, London, Paris, Frankfurt and Rome sit at €60-€150 in winter, €100-€220 in the shoulder months of May, June, September and October, and €180-€350 at the July-August peak. Book Ryanair and Vueling direct for the keenest fares and watch the baggage rules. The low-cost carriers run seat sales roughly every 4-6 weeks, with a major January round for the coming summer. Book 6-10 weeks ahead for shoulder season, 3-4 months ahead for July-August.

From North America: Iberia is the only carrier with serious long-haul into Madrid, alongside Delta, United, American and Aer Lingus via Dublin. Shoulder-season fares to Madrid or Barcelona run roughly US$550-$850 return from East Coast hubs (more from the West Coast, and roughly C$750-$1,150 from Canada); summer peak climbs to US$1,000-$1,600. Winter lows dip under US$550 but usually need a stop. Book 3-5 months ahead for summer, 6-10 weeks for the shoulder.

From Australia: there's no nonstop, so you connect through a Gulf or Asian hub (Doha, Dubai, Singapore) onto Madrid or Barcelona — typically A$1,800-$2,600 return in the shoulder, more at peak, and around 24 hours door to door.

Four gateways are worth knowing: Madrid (MAD) to start the classic loop, Barcelona (BCN) to end it, Málaga (AGP) as the cheapest way into Andalucía if the south is your focus, and Palma (PMI) for the Balearics. Open-jaw flights, into Madrid and out of Barcelona or the reverse, usually cost the same as a return and save a three-hour AVE backtrack. On Multiday.tours you'll see live Kiwi fares next to the tour price, so you can weigh the full combined cost across dates and airports before committing to either piece.
