From the Cantabrian coast to the Balearic Islands, Spanish waters ended May with temperatures never before seen at this time of year. Measurements by Puertos del Estado show record highs for this month along much of the coastline, after an episode of exceptional heat that also sent temperatures soaring on land.
According to the public body (source in Spanish), sea water temperatures reached new records in May, exceeding the previous maximum values recorded for this month. In total, 18 of the 29 buoys in its network registered exceptionally high temperatures.
Specifically, 12 of the 15 buoys in the Offshore Network and 6 of the 14 in the Coastal Network recorded their highest values since their respective data series began. The records were spread across much of the Spanish coastline. All the buoys located off Galicia and in the Cantabrian Sea registered all-time highs, as did numerous stations in the Mediterranean.
