Why does Brussels still have nowhere to swim outdoors as Belgium’s summers grow hotter?
Belgium’s weather service reported this week that summer 2026 brought three official heatwaves and is likely to be the warmest since national observations began, yet Brussels ended the season without a public outdoor swimming site.
People without private gardens, air conditioning or easy transport outside Brussels have fewer ways to cool down safely during extreme heat. The shortage therefore touches public health, climate adaptation and equal access to public space.
’s Royal Meteorological Institute said this week that summer 2026 brought three official heatwaves and is likely to become the country’s warmest summer since observations began in 1833, exposing an increasingly conspicuous gap in : the capital finished another exceptionally hot season without a public place to swim outdoors. The contrast with , where residents can use municipal pools, provincial recreation grounds and newly recognised bathing zones, turns access to cooling into a practical question for everyone living in the —not simply a summer amenity debate.
The immediate heat alert has passed. The RMI currently has no heat warning in force, but its provisional figures through 23 August put ’s average temperature at 20.8°C, compared with a 1991–2020 norm of 18.4°C. Earlier in August, activated the warning phase of its ozone and heat plan as temperatures were forecast to reach 36°C. The federal plan identifies children, older people, people living alone and those with chronic conditions among the groups requiring particular protection.
For residents, official advice to seek cooler places runs into the city’s limited public infrastructure. Flow, a temporary pool beside the canal in , closed in May 2025 after four years. Its organiser, the non-profit , said the small, partly experimental installation was never intended to substitute for a permanent regional facility. Co-founder Paul Steinbrück has since described Brussels as one of the few major European cities without a public outdoor pool and continues to campaign for accessible swimming water.
politicians respond that projects are moving, albeit slowly. In May, State Secretary for Urban Development Ans Persoons said an outdoor pool planned for the roof of the Manufakture development at the Abattoir site in was genuinely progressing. BRUZZ reported that the Brussels Region, the Flemish Community Commission and Anderlecht municipality were involved, with procurement expected in 2026 and construction envisaged from 2029 if the schedule holds. sports councillor Florence Frelinx nevertheless declined to promise an opening date. is separately studying a natural pool on the former Pasteur Institute site, while plans at Neerpede remain entangled in legal proceedings.
Those positions reflect two different readings of the problem. treats Flow’s disappearance as a political wake-up call: temporary experiments have demonstrated demand, it argues, and leaving them open indefinitely can allow governments to postpone a durable solution. Public authorities emphasise the harder delivery questions—land ownership, permits, water quality, lifeguards, construction costs and operating budgets. Experience in supports that caution: VRT NWS has documented outdoor pools limiting opening days or closing because ageing installations and staffing costs became financially unsustainable.
Yet neighbouring cities show that these obstacles are policy choices rather than immutable barriers. opened three supervised Seine bathing sites for a second summer in July, with free access, lifeguards and daily water-quality testing; the city also offers swimming in the Canal Saint-Martin, Bassin de la Villette and sports centres. cannot simply copy the Seine model—the canal’s navigation, pollution and governance constraints differ—but Paris demonstrates what sustained investment and clearly assigned responsibility can deliver.
The broader issue is climate adaptation and social inequality. The European Environment Agency says parks, trees, riverbanks and other green and blue spaces can reduce heat exposure, while lower-income urban neighbourhoods commonly have less access to them. A swimming facility cannot cool an entire city, but an affordable, supervised pool offers respite to residents who lack gardens, air conditioning or the means to travel beyond the region. It also creates a shared public space rather than making relief dependent on private consumption.
The next concrete test is whether the Manufakture tender advances and receives financing despite ’ difficult political and budgetary environment. Residents should also watch the feasibility study and the legal fate of Neerpede. Until one of those projects opens, Brussels’ heat policy will continue to rely mainly on warnings, drinking water, shaded spaces and individual precautions—useful measures, but a thinner cooling offer than many residents can find just outside the capital or in comparable European cities.
Impact
Regional — Flanders offers more open-air options through municipal pools, recreation domains and designated bathing zones, although capacity, staffing and operating costs remain constraints. Brussels residents often have to travel across the regional boundary to use them.
Local — The immediate gap affects Anderlecht and the wider Brussels-Capital Region, where Flow’s 2025 closure removed the only public outdoor swimming option. Residents must use indoor pools or travel outside the region, including to facilities and bathing zones in Flanders. The proposed Manufakture rooftop pool could eventually restore an Anderlecht venue, but construction is envisaged only from 2029 and depends on procurement and financing. Until another project opens, local heat plans cannot provide residents with a public outdoor swimming site during hot periods.
International — The shortage connects Brussels to a wider European debate about unequal access to urban green and blue spaces, documented by the European Environment Agency. Paris provides a practical cross-border comparison: it operates supervised outdoor bathing sites with lifeguards and daily water-quality testing. That example does not automatically transfer to Brussels, but it shows how another European capital combines public access with safety controls. For EU institution staff and other international residents, Brussels currently offers no equivalent public outdoor swimming option within the capital region.
What it means for you
Brussels residents should not plan on having a public outdoor swimming site in the capital during the current hot-weather season. Anyone seeking outdoor bathing must check facilities and designated zones in Flanders, including access rules, capacity and transport before travelling. During official heat alerts, follow the City of Brussels and federal ozone-and-heat guidance, particularly for children, older people and people with health vulnerabilities. The next concrete infrastructure milestone is the Manufakture procurement and financing process; even if it proceeds, construction is envisaged only from 2029, not immediate opening.
Opposing perspectives
- Pool is Cool and outdoor-swimming advocates
Pool is Cool argues that Flow proved inclusive outdoor swimming is feasible and popular in Brussels. The group calls its closure a wake-up call and says continuing a small temporary installation would merely conceal the failure to deliver a permanent regional facility.
- Brussels and municipal project authorities
Officials including Ans Persoons point to the planned Manufakture pool as evidence that a permanent solution is advancing. Their framing stresses procurement, land, permits, financing and safe operation, while sports councillor Florence Frelinx has avoided committing to an opening date.
- Flemish pool operators facing operating costs
Operators documented by VRT NWS say outdoor pools require lifeguards and other staff even when poor weather suppresses attendance. Their experience complicates the idea that every city can sustainably maintain a conventional seasonal pool without substantial public support.
