When to go
Spain is four countries under one flag when it comes to weather. The north is green and cool when the south is scorched; the Canaries ignore the seasons almost entirely; Madrid is a spring and autumn city that happens to be in the middle of a hot plateau. Timing is the single biggest decision you will make, and it costs nothing.
Prices, crowds and closures follow the calendar more than they follow the weather.
Late April to mid-June, and September to late October. Warm days, long light, thinner crowds, and the countryside either green or golden. If you can only choose one variable, choose this one.
July and August are not a write-off, they are a redirection. The interior is genuinely punishing and the big southern cities are at their worst. Head north to Asturias, Galicia, Cantabria and the Basque coast, or go high into the Pyrenees and Picos, and these become two of the best months of the year.
Winter is underrated. Seville and Valencia are mild and quiet, the Canaries are proper beach weather, the ski season is open, and Madrid in January is a museum city with no queue and a table waiting.
Watch the holidays, not just the season. Holy Week, the April fairs, Las Fallas, San Fermín and the 15th of August each rewrite a city for a week. That is either the reason to go or the reason to go another week, and it is rarely in between.
What each month is actually like
January
Good- —Three Kings, 6 January — the real Christmas in Spain: parades on the 5th, most shops shut on the 6th
- —Cider season in Asturias — txotx, the barrel-opening ritual, runs into spring

Good- —Carnaval — the two to know are Cádiz (chirigotas, satire, an entire month of it) and Santa Cruz de Tenerife
- —Almond blossom, Valle del Jerte — mid-February into mid-March
March
Good- —Las Fallas, Valencia, 15–19 March — the city is loud, crowded and worth seeing once
- —Holy Week, when Easter falls early
April
Best- —Semana Santa — the great processions are Seville, Málaga, Valladolid and Zamora

Temperatures and crowds describe the typical pattern for the month, not a forecast. The Best, Good and Hard verdict is our editorial judgement rather than a measurement.
The festivals worth planning around
Spain's calendar moves hotel prices more than its weather does. These are the dates that reshape a city for a week, and when the booking actually has to happen.
Semana Santa
Hotels a year ahead. Bleacher seats months ahead. The street itself is free.
Feria de Abril de Sevilla
The hotel is the booking, made a year out. The fairground is free and vast; the casetas are private.
Las Fallas
Central hotels six months ahead. The daily mascletà at 2pm is the thing to stand under.
San Fermín
Accommodation by February. The running is at 8am; everything else happens the night before.
La Tomatina
Tickets are capped and sell out. The village has almost no beds; base in Valencia.
Carnaval
Cádiz fills for the first weekend. The dates move with Easter.
Vendimia and San Mateo
Logroño hotels fill for San Mateo week. Winery harvest visits need booking ahead.
Saffron harvest
Almost no hotel capacity in the villages. Base in Toledo or Albacete and drive.
What shuts, and when
August: the restaurant you wanted is shut
Two to four weeks of holidays, staggered through the month, and it hits small towns hardest. Big cities and coastal resorts absorb it; a village with one good address does not. Check before building a day around a single kitchen.
Mondays: many museums and monuments
Not the national ones, which keep their own schedules and their own closing days, but plenty of municipal and private collections take Monday off. Check the one you actually care about.
Sundays: shops, but not restaurants
Retail shuts across most of the country. Markets, bars and museums largely stay open, and Sunday lunch is the busiest service of the week — book it.
Siesta is a schedule, not a nap
Small-town shops and businesses in the south still close roughly 2–5pm. Cities, chains and supermarkets ignore it entirely. Plan the middle of the day around lunch and a museum, not shopping.
Public holidays carry their own local logic
1 and 6 January, Good Friday, 1 May, 15 August, 12 October, 1 November, 6 and 8 December and 25 December are national. Every town adds two of its own, and nobody publishes them where a visitor will find them. Ask the hotel desk, and treat the answer as a plan.
The best months where you are going
Spring is the point. July and August belong to the coast only.
Pyrenees in June, the Mudejar towns and Zaragoza in October.
The rare region where August is the best month of the year.
May has wildflowers and room to move; July and August are expensive and packed.
Rain is a feature, not a problem. Late September is the sweet spot.
Warm year-round. The reliable winter escape.
The same green-coast logic as Asturias.
Avoid July and August. Saffron harvest is late October.
Cold, high and clear. The cities work year-round.
Barcelona works in any month; the coast peaks in July and August.
Spring is the reason to come. Summer is punishing and everything shuts.
The driest months by a distance. The rest of the year is genuinely wet.
Harvest and San Mateo in September; the vineyards at their best in October.
July and August empty out and overheat. Spring and autumn are the city's own seasons.
Warm coast, brutal interior summer.
San Fermín if you want the circus; September if you don't.
Fallas in March; the city's best weather from April to June.
Keep going
What sells out, and how far ahead.
Three honest daily budgets, region by region.
Trains, cars, buses and when to fly.
Hours, money, language, health, entry.
Bases, paradors and small stays worth it.
Manners, pressure points and what works.
