Spain Registers Record Sea Temperatures in May, Driven by Climate Change

Record Sea Temperatures and Contributing Factors

Unprecedented May Sea Temperatures Along Spain's Coastline

June 2 (Reuters) - Spain registered record sea temperatures for the month of May along much of its coastline, the country's port authority said on Tuesday, as the UN forecast a moderate or possibly strong El Nino, which could drive up global temperatures in coming months.

Deep-Water and Coastal Buoy Data

Twelve out of 15 deep-water buoys recorded their highest-ever temperatures for the month of May, as well as six out of 14 buoys along the coast, according to the Spanish port authority.

Role of Climate Change and Weather Patterns

Impact of Human-Caused Climate Change

Human-caused climate change was behind the phenomenon, said Ruben del Campo, spokesperson for Spanish weather agency AEMET.

Record-Breaking Temperature Trends

"Over the last decade, there have been just seven record-breaking cold days, whereas we have had 221 record-breaking hot days," del Campo said, adding that this reflected a constant rise in global average temperatures.

El Nino's Influence and Future Outlook

However, del Campo added, May's record sea temperatures were unrelated to El Nino, which will potentially begin to emerge in the Pacific in the coming months and reach its peak in October and November.

  • AEMET underscores human‑driven climate change as the cause; anomalously high sea surface temperatures exceeded seasonal norms by up to 6 °C in parts of the Cantabrian and Mediterranean (eltiempo.es)
  • The UN’s WMO forecasts a likely moderate to strong El Niño later in 2026, which could further elevate global temperatures and intensify extreme weather risks (ca.marketscreener.com)
