Huelva sits in southwestern Spain, where a Mediterranean-influenced climate with strong Atlantic character brings a distinct wet season from autumn through spring and very dry, hot summers.
On Spain’s Atlantic coast near the Portuguese border, the city’s low-lying position near the Odiel and Tinto river mouths adds a tidal dimension to its flood risk. Because the wet season here is spread over several months rather than concentrated into single extreme events like Spain’s eastern coast, flooding tends to build gradually as rivers rise over days, and AEMET’s radar network helps track these longer wet spells.
