Heat episodes will only grow more frequent in the years ahead
As Barcelona's summer heat pressed past 30 degrees Celsius, the city's zoo activated a layered protocol of cooling measures — frozen treats, misting systems, and mud baths — to shield its animals from conditions that were once exceptional but are becoming routine. The gesture is small in scale yet significant in meaning: a public institution quietly adapting its rhythms to a climate that no longer behaves as it once did. The zoo's director has acknowledged what the protocol implies — that this is not a crisis response but a rehearsal for a warmer future.
- Temperatures surging past 30°C across Barcelona forced the zoo into an accelerated mode of care, with animal welfare hanging in the balance during the hottest hours of the day.
- Elephants were hosed down, primates received frozen fruit ice cream, and suricates were served worm slushies — each species getting a tailored intervention against the heat.
- Water stations were multiplied and refreshed constantly, mud pools cleaned and refilled, and sleeping quarters fitted with enhanced ventilation to prevent enclosures from becoming traps.
- The zoo's director has named the uncomfortable truth: these extreme heat episodes will grow more frequent, and the facility is already redesigning itself — for the animals and for the visitors — with that future in mind.
When temperatures climbed past 30 degrees Celsius in Barcelona on Tuesday, the city's zoo shifted into a different mode of operation. Its heat protocol — a coordinated set of interventions refined over time — moved from standby to active, touching nearly every corner of the facility.
The measures are both practical and inventive. Water stations multiplied across the grounds, refreshed constantly so animals always had access to cool water. Mud pools and bathing areas were cleaned and refilled more often than usual, particularly vital for elephants, which depend on them to regulate body temperature. The largest mammals — elephants, bison, buffalo — were sprayed directly with hoses and sprinklers, while sleeping quarters received improved ventilation and climate adjustments.
Food became a cooling tool as well. Primates and giraffes received frozen fruit treats and ice cream made from broth or juice. Suricates got slushies of ground worms — a refreshing delicacy by any measure. These offerings weren't merely comforting; they helped animals manage the physiological stress of extreme heat.
Zoo director Anton Alarcón was candid about what all of this signals. These are not emergency measures, he suggested, but the new baseline — responses to a climate that is shifting in ways the facility can no longer ignore. The zoo is already studying how to improve conditions for both animals and visitors, recognizing that summer comfort will define the experience of any public space in Barcelona for years to come. The protocol, in this sense, is less a solution than an adaptation — an institutional acknowledgment that the work of caring for animals must evolve alongside the climate itself.
When the thermometer climbs past 30 degrees Celsius, the Barcelona Zoo shifts into a different mode of operation. On Tuesday, as temperatures soared across the city, the facility activated its heat protocol—a coordinated set of interventions designed to keep its animals comfortable and hydrated through the worst of the day.
The strategy is straightforward in concept but intricate in execution. The zoo deploys additional water stations throughout the grounds and refreshes them constantly, ensuring animals always have access to cool drinking water. The bathing areas and mud zones—spaces that matter enormously for species like elephants, which rely on them to regulate body temperature—get cleaned and refilled more frequently. For the largest mammals, the approach becomes more direct: elephants, bison, and buffalo are sprayed down with hoses and sprinklers. In the sleeping quarters, the zoo enhances air circulation and adjusts climate control systems to prevent the enclosures from becoming unbearable.
Food becomes a tool for cooling as well. Primates and giraffes receive frozen fruit and ice cream made from broth or fruit juice—treats that provide both nutrition and relief. Suricates get their own version: slushies made from ground worms, a delicacy that happens to be refreshing on a hot day. These frozen offerings do more than comfort the animals; they help their bodies manage the stress of extreme heat.
Anton Alarcón, the zoo's director, frames these measures not as emergency responses but as the new normal. He has stated plainly that heat episodes of this intensity will only grow more frequent in the years ahead. That reality is already shaping how the facility thinks about its future. The zoo is actively studying ways to improve conditions not just for the animals in its care, but for the visitors who come to see them—recognizing that summer comfort will become an increasingly central concern for any public space in Barcelona.
These extraordinary measures exist alongside the daily attention the zoo's keepers provide year-round. They are not replacements for standard care but enhancements, calibrated responses to conditions that push animal welfare into new territory. The protocol itself is a kind of adaptation, a institutional acknowledgment that the climate is changing and that the work of caring for animals in captivity must change with it.

These episodes will become more frequent, requiring improvements to animal comfort and visitor experience during summer months— Antoni Alarcón, Barcelona Zoo director
La Conversación del Hearth Otra perspectiva de la historia
Why does a zoo need a special heat protocol at all? Don't animals in the wild deal with heat on their own?
They do, but wild animals have choices we don't give captive ones. They can migrate, find shade in dense forest, dig deeper into burrows. A zoo animal is bounded by its enclosure. The protocol is about compensating for that constraint.
So the frozen treats—that's not just a nice thing, it's actually necessary?
It serves two purposes at once. Yes, it cools them, but it also keeps them engaged and eating during hours when they might otherwise be stressed. A distracted animal is often a calmer one.
The director mentioned these heat waves will become more frequent. Does that mean the zoo is planning to rebuild its facilities?
They're studying it. That's the honest answer. They know the current setup wasn't designed for sustained 30-plus-degree days. Rebuilding takes years and enormous money. For now, they're optimizing what they have.
What about the visitors? You mentioned the director cares about their comfort too.
A zoo in extreme heat is miserable for people. You're standing in the sun, the animals are hiding from it. The experience falls apart. The director is thinking ahead—if summers are going to be hotter, the zoo itself needs to evolve as a place where humans can actually spend time.
Do different animals respond differently to the heat protocol?
Completely. An elephant uses mud and water for thermoregulation in ways a primate doesn't. A suricata's slushie isn't just food; it's species-specific cooling. The keepers know each animal's physiology. That knowledge is what makes the protocol work.
