With the arrival of summer, forests and agricultural lands across the country are threatened by high temperatures, low humidity, and dry vegetation, but also by human activity, which is the main cause of fires in Catalonia, whether by accident or negligence or by intentional acts. Experts and authorities warn that the country has fully entered the high fire risk season and, in fact, this weekend, several simultaneous fires in the natural environment in Lleida have strained emergency services. At present, the Government has activated level 3 out of 4 – very high fire danger – in about fifty municipalities in Ponent and Central Catalonia, and on the eve of Sant Joan's Eve, the Minister of the Interior, Núria Parlon, has asked the public for "maximum caution" when setting off fireworks – they must be at least 500 meters away from forests and natural surroundings – and when lighting bonfires.

Barcelona is preparing for a Sant Joan festival which will be reminiscent of 2019. It is focussing on two points: the first is crowds on the beaches, where around 60,000 people are expected to gather; the other is wooded areas, due to the high risk of fire throughout Catalonia. "We are in a critical moment and any carelessness can cause a fire," warned Security councillor Albert Batlle, who recalled the ban on the use of fire within 500 meters of wooded areas, and remarked that the Guardia Urbana will pay special attention to the parts of the city that are closer to the mountains. The city adds one more recommendation: avoiding as far as possible launching fireworks and sky lanterns, as they pose a fire risk. The head of the Civil Protection, Fire Prevention and Rescue Service, Sebastià Massagué, has asked for "extreme caution" and avoiding this kind of pyrotechnics.
