When the Sirimiri Sets In: Bilbao’s All-Indoor Day

Bilbao gets a great deal of rain, and much of it arrives as sirimiri — a fine, windless drizzle that soaks you slowly while you insist it is barely raining. Locals treat it as weather rather than an event. So should you, because the city is unusually well equipped for it.

The reputation is worse than the reality, though not by much. Long-run climate records put Bilbao at roughly 1,200 millimetres of precipitation a year, spread over about 128 days. November is usually the wettest month at something near 145 millimetres; July and August are the driest, at around 60 to 65. That is more total rain than Manchester receives, delivered on rather fewer days, which tells you most of what you need to know about how it arrives when it arrives. The averages miss the sirimiri entirely, because it barely troubles a rain gauge and still leaves your coat heavy by lunchtime. The one mercy is that it falls without wind, so an umbrella actually functions here. Save the hood for a genuine Atlantic front.

What follows is a full day built on the assumption that you will not want to be outdoors for more than ten minutes at a stretch. It runs from mid-morning to late evening, covers perhaps three kilometres on foot in total, and never strands you far from a door.

Before you set out: four decisions that shape the day

Choose the day of the week deliberately. This is the one thing that can dismantle the whole plan. The Guggenheim is closed most Mondays outside the summer season, as is the Itsasmuseum on the waterfront. The Mercado de la Ribera does not open on Sundays at all, and its produce halls typically wind down by the middle of Saturday. A wet Tuesday to Friday is the version of this day that works without compromise. If your rain lands on a Monday or a Sunday, the substitutions are at the end.

Get a Barik card in the first five minutes. The rechargeable Barik is sold at most metro stations and at the Artxanda funicular for around three euros, with a minimum top-up usually required on top of that. A single zone-one journey typically costs around a euro with the card against roughly a euro and a half for a paper ticket, and the same card covers the metro, the tram, the city buses and both funiculars. The alternative is the Bilbao Bizkaia Card, sold in 24-, 48- and 72-hour versions for approximately ten, fifteen and twenty euros, which bundles unlimited transport and queue priority at the main museums, though not their admission. For a day spent largely on foot in a compact centre, the Barik is the better value; the tourist card earns its keep only if you are also running out to the coast.

While you are underground, look up. The glass entrance hoods over the metro stairs are Norman Foster's work, and Bilbao calls them fosteritos. On a wet day they stop being a design flourish and start being infrastructure.

Book the Guggenheim the night before. Timed entry bought online spares you a queue that forms under an awning too shallow to be of any help.

Do not cross the Zubizuri. Santiago Calatrava's white footbridge is the photograph everyone wants, and its translucent glass deck has a long and well-documented reputation for being treacherous underfoot in the wet. The Deusto bridge, a short way downstream, is dull and dry.

Morning: the Guggenheim, in the right order (from 10am)

Go straight there and go early. The museum generally opens around ten and runs to about seven in the evening from Tuesday to Sunday, with later closing in high summer and over Easter. Admission is typically around fifteen euros for most of the year and closer to eighteen during the summer peak, with under-18s admitted free. Check the current rate when you book, because the seasonal switch catches people out.

Frank Gehry's building deserves a slow first hour before the tour groups thicken, and the trick is to invert the obvious route. Most visitors ride to the top and work down. Start instead on the ground floor with Richard Serra's The Matter of Time, the eight weathering-steel works installed permanently in Gallery 104, the museum's largest room. They were commissioned for that room and made between 1994 and 2005. You walk inside them, which is the entire point, and the experience collapses if you are shuffling behind forty other people. Give it half an hour on your own and it will be the thing you remember.

Take the atrium slowly next — it is the part of the building that best explains what Gehry was doing with the rest of it — and only then go up to the temporary shows on the upper floors. Allow two and a half to three hours in total.

The outdoor works are the day's one unavoidable compromise. Jeff Koons's Puppy stands at the entrance, Louise Bourgeois's spider Maman on the river terrace, and Fujiko Nakaya's fog sculpture drifts across the pond on a timer. In sirimiri the fog piece is arguably better than in sunshine — mist meeting mist. Give the three of them ten minutes under an umbrella on the way in and do not linger.

If you would rather eat inside the building than move on, Nerua occupies a room beside Gallery 104 under the chef Josean Alija and has its own street entrance. It holds a Michelin star and needs booking well in advance. It is a different day from the one described here, and a considerably more expensive one.

Midday: the Mercado de la Ribera (from 1pm)

A walk of about twenty minutes upriver brings you to the covered market on the water's edge, a 1929 building whose stained glass sits high above the produce halls. Guinness World Records recognised it in 1990 as the largest covered food market in the world, a title the building still trades on.

The ground floor is a working market, open mornings from Monday to Saturday and generally winding down in the early afternoon, closed on Sundays. Upstairs is the part you came for: a gallery of pintxo counters that typically opens from around midday and keeps going into the evening. Order narrowly rather than broadly — a few small plates and a glass of txakoli, the faintly sparkling Basque white poured from a height to rough it up, will come to somewhere in the region of fifteen to twenty euros a head.

If it is Sunday and the market is shut, walk five minutes further into the old town and eat in Plaza Nueva instead, where the bars keep weekend hours and the arcade keeps you dry.

Early afternoon: the Casco Viejo, under arcades (from 2.30pm)

Cross into the Casco Viejo, the medieval core that grew around the Siete Calles, the seven original streets. Plaza Nueva, the neoclassical square at its heart, is arcaded on all four sides, which makes it the default wet-weather refuge in the city: you can move between half a dozen bars without ever opening an umbrella. Sunday mornings usually bring a collectors' market under the same arcades — stamps, coins, old books, caged birds — which is worth timing a visit around if your rain falls at the weekend.

Two indoor stops here are worth the money. The Euskal Museoa on Plaza Unamuno reopened in June 2026 after nearly five years closed for a rebuild inside a seventeenth-century Jesuit college, and it is, to our eyes, the clearest single account of Basque material culture in the city, from the Mikeldi idol to the fishing and shepherding rooms. Entry is usually free on Wednesdays; on other days expect a modest charge. A further phase of the building was still being handed over through the autumn of 2026, so parts of it may be behind hoarding.

The Gothic Catedral de Santiago, a few streets away, is a stop on the coastal Camino and is described by the city's tourist office as Bilbao's oldest surviving monument. Tickets are around six euros and generally include the cloister and an audio guide. It usually opens mid-morning from Monday to Saturday and only in the early afternoon on Sundays.

Late afternoon: a wine warehouse or a brand-new museum (from 4.30pm)

Two good options, and which you take depends partly on the calendar.

Azkuna Zentroa is the safer bet, and costs nothing to enter. Philippe Starck converted Bilbao's 1909 municipal wine warehouse into a cultural centre whose atrium stands on 43 columns, each one designed differently by the set designer Lorenzo Baraldi and no two alike. Above them sits a swimming pool with a glass floor, so from the atrium you can watch swimmers overhead. The building also holds a library, cinemas and an exhibition hall, and it typically opens early in the morning and stays open until around eleven at night, which makes it the most forgiving stop on this list.

The alternative is the Museo de Bellas Artes, in the Abando district beside Doña Casilda park, which holds one of Spain's strongest collections outside Madrid — Flemish primitives, El Greco, Goya, Zurbarán, and a deep run of Basque modernists. It has spent years under a Foster + Partners expansion called Agravitas, developed with Luis María Uriarte, which lifts roughly six thousand square metres of new building above the old one and adds a glass atrium opening onto the park. The temporary pavilion that had been showing the collection closed at the end of August 2026, and the completed museum was scheduled to open on 6 October 2026, with free admission reported for the opening days. Given how often this project's dates have moved, confirm before you walk over.

Evening: coffee at Albia, then the pintxo route (from 7pm)

Take a break at Café Iruña, facing the Jardines de Albia in Abando. It opened in 1903, its neo-Mudéjar tiled interior survived a careful refurbishment a few years ago, and the house speciality is a skewer of spiced lamb. Coffee and a skewer will run to a few euros.

Then work the bars, and understand the etiquette before you start: you stand, you order one thing, you pay, you move on. Sitting down for a full meal is not what this is.

In the Casco Viejo, Plaza Nueva alone will fill an evening — Gure Toki for modern constructions on a traditional base, Sorginzulo for croquettes, Víctor Montes in a room that began as a grocer's shop in 1849. A street away, Berton on Calle Jardines runs traditional and modern counters side by side, Xukela on Calle del Perro is tiny and permanently full, and Gatz on Calle Santa María is where to go if you have decided you want txuleta rather than another pintxo.

If you want a younger and less visited crowd, cross back into the Ensanche and walk Ledesma and Diputación. La Viña del Ensanche has been on Diputación since 1927 and is run by the third generation of the same family; its Iberian ham is the reason to go. El Globo, a few doors along, is known for a gratinated spider-crab pintxo. Individual pintxos in this part of town typically run from around three to six euros, and a proper evening of it lands somewhere near twenty-five.

What to skip, when to come, and what the day costs

Skip the Itsasmuseum in heavy rain, tempting as a maritime museum sounds on a wet day. The best of it is the old Euskalduna dry dock and the boats moored in it, and all of that is outdoors. Keep it for a dry morning: it usually opens Tuesday to Sunday from late morning, costs around ten euros, and is often free on Sunday afternoons and on Tuesdays during the school year.

Skip the riverside sculpture walk entirely, and skip the funicular unless the sky genuinely clears.

On a Monday, when the Guggenheim and the Itsasmuseum are both shut, invert the day: start at Azkuna Zentroa when it opens, take the Casco Viejo museums through the middle of the day, and hold the market counters and the pintxo bars for the evening.

On when to come. The day described here is at its most useful between October and April, which is also when you are most likely to need it. November is the wettest month on the record and December is not far behind. Two dates are worth knowing about. Aste Nagusia, the city's big festival in the second half of August, packs the centre and rain stops nobody. And the Santo Tomás fair, held around 21 December, fills Plaza Nueva with stalls selling talo and txistorra under the arcades, which is by our reckoning the best wet-weather afternoon in the Bilbao year.

Roughly what it costs. For one adult, museum admissions plus lunch, coffee and an evening of pintxos, with transport, budget somewhere in the region of sixty-five to eighty euros. Cut fifteen off that by eating at market counters twice and skipping the cathedral; add whatever you like at the top end by booking Nerua.

Tip: If the sky clears for even twenty minutes, drop everything and take the Artxanda funicular from the Campo Volantín side of the river. The ride is a matter of minutes, departures are usually about a quarter of an hour apart, and a return ticket costs around four euros — considerably less with a Barik card. The view over the river valley is the one that explains the city, and Bilbao's clear spells rarely last.
