Water reserves in the Balearic Islands have shown a significant increase during the month of November, reaching an average of 54%, according to data published by the Conselleria del Mar y del Ciclo del Agua. However, Ibiza y Formentera continue to lag behind, with Ibiza registering an increase from 32% to 37%, the lowest percentage in the archipelago. Formentera has also experienced a slight improvement, although both islands remain the most vulnerable areas, reflecting the difficulty of rainfall to meet water needs in this region.
Pre-alert for Ibiza and Formentera
Despite the recovery in reserves, Ibiza and Formentera remain under pre-alert, as well as much of the Balearic territory, which reports 68.9% in this situation. According to the Conselleria, there have been no significant changes in water management scenarios, and Formentera remains on alert due to its limited storage capacity and adverse weather conditions.
Weather conditions and annual precipitation
November was a month of normal rainfall in the Balearic Islands, with an average of 83.7 l/m², slightly below historical values. In the case of Ibiza, accumulated rainfall reached 77.9 l/m², exceeding its usual average of 67.2 l/m², while Formentera recorded 43.6 l/m², below the historical average of 53.1 l/m². In terms of annual accumulated rainfall, the Pitiusas are at 80% of their historical average, standing out as the most vulnerable region of the Balearic Islands in terms of water availability.
An unseasonably warm November
In addition, November has been exceptionally warm in the archipelago, with an average temperature of 16.7 ºC, which represents an anomaly of +2.3 ºC with respect to the usual values. These anomalous conditions, with temperatures higher than expected, have contributed to the tension in the management of water resources, particularly in the most affected areas such as the Pitiusas.
