Balearic water reserves closed the past month of June with a concerning decline, standing at 48% of total capacity, three points below the previous month (51%) and two points less than in June 2024 (50%). By island, Mallorca has dropped from 52% to 50%, Menorca from 48% to 42%, and Eivissa has decreased from 36% to 34%. The drop in reserves highlights a sustained negative trend, worsened by the lack of rainfall and high temperatures. According to the regional government, everything suggests that Balearic water reserves will continue to decrease during the month of July, which could further worsen the situation in the coming months.

Balearic water reserves

At present, the drought scenario extends across almost the entire Balearic territory. Currently, 98.4% of the Demand Units (UD) are in a pre-alert situation, while only Formentera – representing 1.6% of the territory – maintains normal status. Nine UD have shown a worsening in the drought index: Menorca, Manacor-Felanitx, Migjorn, Es Pla, Palma-Alcúdia, North Tramuntana, South Tramuntana, Eivissa and Formentera. Only Artà shows a slight improvement.

The overall index of the Hydrographic Demarcation remains at 0.400, the same value as a year ago, although clearly lower than that recorded in 2023 (0.503), reinforcing the downward trend in water indicators.

June the driest since 1961

The situation has been exacerbated by extremely adverse weather conditions. According to the State Meteorological Agency (AEMET), June was a very dry month in the Balearic Islands, with an average rainfall of just 0.1 litres per square metre (l/m²), well below the usual 15.3 l/m². This makes it the driest June since records began in 1961.

Broken down by islands, Mallorca received only 0.2 l/m² (compared to the usual 16.7 l/m²), Menorca 0.1 l/m² (vs 13.3 l/m²), and Eivissa and Formentera recorded no rainfall at all (0.0 l/m²).

In addition to the lack of rain, there has been a significant rise in temperatures. June was extremely hot, with an average of 25.3 ºC across the archipelago and a positive anomaly of +3.3 ºC above normal.
