The news of a record-breaking wave surging through Mexico City’s inland waterways this week may feel like a distant spectacle for Britons. But for those of us who live by the rhythms of the sea, it strikes a familiar chord. It speaks to the hidden power of water, the fragility of our defences, and the price we pay when safety takes a back seat. While Mexico City’s wave was an anomaly, here in the UK we face our own coastal crisis: a string of near misses, ageing flood barriers, and a deepening regional inequality that leaves seaside towns exposed.
The British coastal safety system, once the envy of the world, is fraying at the edges. The Environment Agency’s own data shows that nearly one in six homes in England is at risk of flooding. Yet funding for flood defences has been cut by 25% in real terms since 2010, according to the National Audit Office. This is not just a matter of crumbling concrete. It is a matter of lives and livelihoods. The fishing villages of Cornwall, the resorts of Blackpool, the quaysides of Hull: these are places where a single storm surge can wash away a year’s work.
The comparison to Mexico City is not idle. The capital’s wave was triggered by a rare combination of subterranean currents and heavy rainfall. But its impact was magnified by years of underinvestment in drainage and flood prevention, a tale all too familiar to residents of Clacton-on-Sea or Skegness. In 2013, a tidal surge devastated the Norfolk coast, causing £400 million in damages. Flood insurance premiums have since soared, pricing many low-income families out of cover. The result is a postcode lottery: protect the rich, neglect the rest.
We must ask ourselves why innovation in coastal safety is so patchy. The Dutch have installed floating barriers and smart monitoring systems. The Chinese have built sponge cities to absorb stormwater. But here, we rely on Victorian-era sea walls and a patchwork of local councils struggling to balance their books. The government’s own flood resilience strategy, published in 2020, promised a shift from “build and defend” to “adapt and recover”. Yet the budget for natural flood management, such as salt marshes and sand dunes, remains a fraction of the total.
The union for environment agency staff, PCS, has long warned that cuts to frontline services leave us vulnerable. ‘We have lost 1,500 jobs in the last decade,” says a spokesperson. “That means fewer engineers inspecting defences, fewer hydrologists forecasting floods, and slower responses to emergencies.” Meanwhile, the Labour Party’s latest manifesto commits to a £1 billion investment in flood defences, but critics argue this is too little, too late.
For the kitchen table economy, this is not an abstract issue. Floods destroy homes, wipe out small businesses, and push families into debt. A 2022 survey by the Joseph Rowntree Foundation found that those in flood-hit areas are four times more likely to fall behind on rent or mortgage payments. And the mental health toll is severe: anxiety, depression, even post-traumatic stress.
We should not look to Mexico City for novelty. We should look to it for warning. The sound of a record wave should be a national alert. The government must accelerate investment, empower communities to build their own resilience, and ensure that the cost of safety does not fall on the shoulders of those least able to bear it. Because for the family in a terraced house in Whitby, the next storm is not a question of if, but when.
