Last January, Mallorca experienced a notable decrease in rainfall, as confirmed by the State Meteorological Agency (Aemet). According to its data, the average rainfall was 1.8% 37% compared to the historical average, registering only 37,4 liters per square meter compared to 59,8 usual liters at this time.
This reduction in rainfall has meant a total deficit of 81,5 cubic hectometres of water, a considerable amount that highlights the dryness of the period. To put it in perspective, this volume of water is equivalent to approximately seven times the combined capacity of the Tramuntana, Gorg Blau and Cúber reservoirs, whose maximum storage is 12 cubic hectometres.
Impact on water reserves
This rainfall deficit has had direct consequences on the island water reservesCompared to the previous month, the level of the reservoirs decreased by 53% to 52%, when it is usual in January that the amount of stored water increases due to the winter rainsIf we compare this situation with the same month last year, the difference is also evident: in January 2024, water reserves were four points higher.
Despite this worrying situation, the distribution of rainfall has not been homogeneous throughout the island. Areas such as Pollença, Port de Pollença, s'Albufera de Muro and Portocolom received more rain than usual. In the case of the Capdepera lighthouse, there were more 62,7 liters per square meter, which represents an increase of 46% compared to the annual average.
Concern about water supply
The decrease in rainfall, combined with higher temperatures than usual, has generated concern among local authoritiesThe Balearic Government has warned that this scenario could hinder the recovery of the island's aquifers and water reserves, which could lead to supply problems during the months of greatest demand.
Therefore, emphasis has been placed on the need to strengthen water saving measures and promote responsible actions in their consumptionThe Government has asked citizens and the different economic sectors to collaborate in order to avoid a further deterioration of the situation. It is insisted that efficient use of water This will be key with the arrival of summer, a period in which consumption increases considerably due to both high temperatures and the arrival of tourists.
Possible measures to address the shortage
Given this situation, the authorities are studying various strategies to guarantee the water supply in the coming months. Among the options being considered are:
Awareness campaigns to promote water savings in homes, hotels and industries.
Optimization in water management in distribution and storage systems.
Strengthening the use of desalinated water, increasing the capacity of desalination plants to reduce dependence on rainfall.
Review of water infrastructure to prevent water loss due to leaks or poor systems.
Although some areas have received above-average rainfall, the impact of the rainfall deficit in January has been significant in Mallorca. The reduction in water reserves together with the forecast of warmer months requires measures to be taken to ensure that water is available on the island. Raising awareness among the population and reinforcement of management strategies will be essential to deal with this situation without critically affecting residents and tourists.
