Barcelona’s climate shelter network lists 550 spaces across all ten districts, and the figure that matters for a decision is a different one: on an August Sunday, 79 indoor spaces are open. The gap is not a cut, it is that the network mixes four things that do not work alike. There are 355 indoor spaces, but also 80 outdoor ones that the register itself warns may not deliver thermal comfort, 54 paying pools with a capacity limit and 61 micro-shelters that are private businesses with fluctuating hours. And the ranking inverts: the Eixample leads the network with 84 spaces and keeps 6 that Sunday, while Ciutat Vella, with 54, holds on to 19.
How many Barcelona climate shelters are genuinely open? The network lists 550, but 195 carry conditions the name does not mention: 80 outdoor spaces that may not cool, 54 paying pools with capacity limits and 61 private businesses meant for short stays. Of the 355 indoor spaces, 326 publish hours, 96 open on Sunday and only 79 open on a Sunday without closing in August.
Which district you live in decides more than the network
This is where the citywide figure misleads most, because the ranking turns upside down.
| District | Open on the August Sunday | In the network |
|---|---|---|
| Les Corts | 2 spaces | 28 spaces |
| Sants-Montjuïc | 2 spaces | 58 spaces |
| Sarrià-Sant Gervasi | 2 spaces | 39 spaces |
| Horta-Guinardó | 3 spaces | 48 spaces |
| Eixample | 6 spaces | 84 spaces |
| Gràcia | 8 spaces | 36 spaces |
| Nou Barris | 8 spaces | 57 spaces |
| Sant Martí | 12 spaces | 71 spaces |
| Sant Andreu | 17 spaces | 75 spaces |
| Ciutat Vella | 19 spaces | 54 spaces |
Ciutat Vella holds fewer spaces than the Eixample and keeps three times as many that Sunday, because museums and daily-opening facilities weigh heavily there. Les Corts, Sants-Montjuïc and Sarrià-Sant Gervasi keep two each, and Horta-Guinardó three.
In those four districts the weekend plan in real heat is not the neighbourhood shelter: it is travelling or paying to get in.
What the 79 actually are, and which cost nothing
The entry terms are the part that changes the plan, because they are not the same across the list.
Of the 79, 22 are sports centres and 8 are museums. Both charge their own admission or membership, and the register publishes no price: you get in the way you would on any other day. The genuinely free walk-in options are above all the 14 community centres and the 4 libraries, plus one civic centre and a handful of other facilities.
| Type | Of the 79 |
|---|---|
| Sports centre | 22 spaces |
| Community centre | 14 spaces |
| Museum | 8 spaces |
| Library | 4 spaces |
| Other facilities | 31 spaces |
Only 4 libraries staying open is the figure that surprises most, because the library is what everyone pictures when they think of somewhere cool and free.
The four types and why they are not equivalent
Knowing which of the four you are heading to is worth the thirty seconds it takes.
The 355 indoor spaces are the core: libraries, community centres, civic centres, sports facilities and museums. They hold an entire afternoon.
The 80 outdoor spaces — parks, gardens, squares and water-play areas — carry a literal warning from the register: during high-temperature episodes they may not offer the thermal comfort needed. In other words, the day it hits 38 degrees is the day they work least.
The 54 pools are paying shelters subject to a capacity limit, also per the register.
The 61 micro-shelters belong to private businesses, are meant for a short stay, and the register warns their hours may fluctuate. They include pharmacies, bookshops, opticians, insurance offices and shopping centres such as the Maremàgnum and L’Illa Diagonal.
How the funnel closes
It narrows in three steps and each one takes a slice of the network.
Of the 355 indoor spaces, 29 publish no hours at all, so they cannot be counted on without phoning. Of the 326 that do, 236 open on Saturday but only 96 open on Sunday. And 101 close through August.
Cross the two and 79 indoor spaces remain open on an August Sunday. That is 14 % of the headline figure.
| What is left | Spaces | What drops out |
|---|---|---|
| Open on Sunday and in August | 79 spaces | 17 close through August |
| Open on Sunday | 96 spaces | 230 do not open on Sunday |
| Indoor with published hours | 326 spaces | 29 publish no hours |
| Indoor only | 355 spaces | 195 are outdoor, paying or private |
| The whole network | 550 spaces | — |
They work in winter too
Only 73 of the 326 indoor spaces with published hours declare a date window such as 16 June to 13 September or 24 June to 31 July. The other 253 run all year and do the same job on a cold day: a heated indoor room, open and mostly free.
Plans for the hot end of the year are in the heat and summer guide, what closes in the quietest month is in Barcelona in August, and if the problem is rain rather than temperature, the rainy day guide sorts the indoor options.
Three checks before leaving the house
These are the ones that save a wasted trip, and all three come from the same register.
If the name starts with gardens, square, park or water-play area, it is one of the 80 outdoor spaces and the council’s own warning says it may not help. If it is a pharmacy or a bookshop, it is one of the 61 micro-shelters: a short stay, not an afternoon. And if it is one of the 54 pools, you pay and there is a capacity limit.
The day of the week matters more than the address. With 96 spaces open on Sunday, 101 closing in August and 29 publishing no hours, the same facility that saved you on a Wednesday in July can be shut the following Sunday.
For days when the plan is to be outside rather than sheltering, the Barcelona playgrounds guide covers the free outdoor option and dogs off the lead the hours that apply with a dog.

How many climate shelters does Barcelona have?
