As Spaniards summer at Barcelona’s beaches, some worry about the erosion of coastline

CATALONIA, SPAIN, JUL 21 – Building individual seawalls transfers erosion risk to neighbors, doubling rates and worsening shoreline loss amid rising seas, experts say this threatens coastal communities and tourism.

  • In April 2024, a storm with waves up to 16 feet eroded parts of Montgat beach near Barcelona, leaving sections virtually without sand.
  • This event followed ongoing climate change impacts, including rising sea levels and intensifying storms, which accelerate erosion of Barcelona's man-made beaches.
  • Authorities have responded by replenishing sand and building breakwaters, but Ramon Torra states stopping sand loss is more critical than just adding sand.
  • Maritime engineer Agustín Sánchez-Arcilla reports sea levels have risen fourfold along the Catalan coast since the 1990s, with a 5.5-inch rise and average waves 11.8 inches higher in 25 years.
  • The erosion threatens local infrastructure and economies, implying urgent investment of around €60 million to stabilize Barcelona's coastline amid a worsening climate crisis.
