Water storage levels in the Balearic Islands continued to improve in December, reaching 49% of capacity, one percentage point higher than in November. Despite this increase, overall reserves remain below last year’s level, when they stood at 52%.

All islands recorded gains over the month. Mallorca rose to 49%, Menorca to 46% and Ibiza to 48%, confirming a broadly positive trend across the archipelago.

At the demand-unit level, eight areas reported higher reserve levels, with Manacor-Felanitx standing out after returning to a normal status, and Tramuntana South showing a particularly notable improvement.

Water reserves in the Balearic Islands rose to 49% in December, with signs of gradual recovery

At present, 23% of the territory is classified as being in a normal situation, while 60.8% remains under pre-alert conditions. Meanwhile, Es Pla and Artà, accounting for 16.2%, continue to be in an alert scenario.

The overall Hydrological District Index stands at 0.421, lower than figures recorded one and two years ago, reflecting a still constrained situation but with short-term positive momentum.

Rainfall played a key role in this improvement. According to Spain’s State Meteorological Agency (AEMET), December was wetter than average, with a mean rainfall of 88.9 l/m² across the islands. Annual accumulated precipitation has now reached 102% of the historical average.

Temperatures, however, were well above normal, with an average of 12.4 ºC, representing a +1.1 ºC anomaly.

Looking ahead to January, forecasts suggest that water reserves are likely to continue increasing, with no major changes expected in the current scenarios, although further improvements may become established in some demand units.
