Researchers have identified significant threats to some of the world’s most celebrated surfing destinations, according to findings published in the journal Climatic Change. The analysis examined 57 surf breaks across 13 world surfing reserves in eight countries, involving input from nearly 200 local experts. The study found that over three-quarters of these breaks face high risk from multiple factors associated with climate change and coastal modification.
Sea level rise and shifting sediment patterns driven by changing rainfall represent primary concerns for the viability of these waves. The delicate oceanographic conditions that create world-class breaks depend on precise combinations of seafloor topography, swell direction and tidal patterns. Global heating disrupts these conditions while also affecting the natural movement of sand and sediment along coastlines. Particularly vulnerable breaks identified in the research include locations in north Devon in the United Kingdom, Noosa in Australia, El Salvador, and multiple sites along California’s coast.
Coastal development presents an additional challenge to wave preservation. Hardened infrastructure such as sea walls, jetties and groynes reduces the ability of beaches and breaks to adapt naturally to environmental changes. In contrast, areas with less modified coastlines demonstrated greater resilience and capacity to shift and relocate sediments in response to climate pressures. Researchers noted that natural coastlines can better accommodate the ongoing changes induced by the climate crisis.
The economic implications extend far beyond the surfing community. Multiple regions depend heavily on surfing-related tourism and spending. Santa Cruz generates approximately $200 million annually from surfing activity, while eastern El Salvador’s economy relies substantially on its renowned point break waves. Local communities benefit from year-round visitor spending that supports restaurants, accommodations, retail establishments and other businesses.
Researchers emphasized the value of local surfer knowledge in developing protective strategies. Several jurisdictions have already implemented safeguards, including Gold Coast in Australia through planning protections, New Zealand’s national significance designations, and Peru’s specialized legislation protecting listed breaks. Scientists are encouraging local surfers to employ assessment tools and collaborate with authorities to defend waves against both development pressures and climate-related changes.
