Valencian Community

The Valencian Community fronts the Mediterranean on Spain's central eastern coast from the Catalonia border at the Ebro delta in the north south through Castellón, Valencia, and the Costa Blanca to Alicante and the Murcia line. Valencia is the regional capital, the third-largest Spanish city, and the working port that handles the bulk of the western Mediterranean container traffic between the Suez approach and Rotterdam. The tide here is the small Mediterranean signal characteristic of the western basin: mean range at the Valencia port gauge is about 0.2 metres, with spring tides reaching close to 0.3 and neaps dropping near flat. The astronomical signal is genuinely tiny because the Mediterranean connects to the Atlantic only through the narrow Strait of Gibraltar. What matters more on a day-to-day basis is meteorological tide. Easterly storms (gota fría / cold-drop low-pressure systems) in autumn can stack water against the coast and lift apparent water level by 30 to 50 centimetres on sustained events, with the most extreme storms producing flash flooding on the coastal plain that the Turia river was diverted around in 1969 after the catastrophic Riada de Valencia flood of October 1957. The defining ecological feature of the southern coast is the Albufera de Valencia, a 21-square-kilometre brackish lagoon separated from the Mediterranean by a narrow sand bar (the dehesa pine forest) ten kilometres south of the city centre. The Albufera was historically a tidal estuary and is now a freshwater lagoon dominated by reed beds and rice cultivation, with the surrounding rice fields providing the bomba and senia rice varieties that make Valencian paella what it is — the dish was born on the lagoon edge as a midday meal for the rice farmers, with eel, snails, garrofó beans, and rabbit cooked in the wide pan over an open fire. The working port at Valencia, the long Malvarrosa and Cabanyal beach corridors immediately north of the harbour, and the marina city built for the 32nd America's Cup in 2007 all read the wider weather pattern more than the tide table. Puertos del Estado is the authoritative Spanish tide source and operates the Valencia reference gauge network.
