June 2025 has been recorded as the warmest June on historical record in Spain, according to data from the State Meteorology Agency ( Aemet ). This remarkable month witnessed a combination of extreme heat and unusual dryness that has raised concerns among environmentalists and citizens alike. Despite the presence of successive storms and weather fluctuations , the overall conditions of the first summer month suggest alarming trends in climate patterns.
Warm and Dry Conditions. Aemet released its meteorological summary for June, confirming an average thermal anomaly of 3.6º Celsius above the normal temperature for this time of year. Notably, the month recorded a precipitation level that’s 68% below the typical rainfall expected in June. This combination of heat and lack of water has transitioned into both environmental concerns and public discussions on sustainability.
Record-Breaking Temperatures. The average temperature during June 2025 reached 23.7º across the Peninsula , marking a significant 0.9º increase above the previous record set in June 2017. The extraordinary heat has prompted many to consider how ongoing climate change is influencing regional weather patterns.
The Balearic Islands have also reported “extremely warm” temperatures, averaging 3.1º above normal. On the other hand, the Canary Islands managed to fare slightly better, with a recorded anomaly of 0.7º , deeming it merely “very warm.” In the northeastern parts of the Peninsula, some regions experienced thermal anomalies exceeding 4.5º , indicating stark regional variations in temperature.

The rainfall data was equally troubling. June’s average precipitation in peninsular Spain was only 21.7 mm , which is over 30% below the typical rainfall levels for the month. Despite experiencing several storm events throughout June, these were insufficient to offset the prevailing dry conditions .
This situation becomes even more alarming considering the storms that were expected to provide relief. Instead, they merely served as a reminder that climate stability is elusive. The Balearic Islands faced the most extreme water scarcity , with rainfall plummeting to an astonishing 99% below the average. The archipelago reported a mere 0.1 mm of rain throughout the month, which is an unprecedented low.
The Canary Islands also faced dry conditions, with recorded rainfall of just 0.7 mm , which is 27% of average June levels. Some isolated regions of the Peninsula did receive rainfall above average, especially the northern plateau and parts of the Ebro valley, but overall, the trend indicates a concerning pattern of dryness.
A Shift in Trends? The previous fall and spring seasons brought ample rainfall, alleviating some of the drought conditions that had plagued the region. Reservoirs and water bodies observed a significant increase in water levels. Citizens had initially viewed this positively, but skepticism remains regarding the sustainability of these conditions amidst growing climate change concerns.
June is the latest in a series of months that have shown drier-than-usual patterns, reminding us of the fragility of this environment. While the earlier rainfalls had filled reservoirs and provided hope, this month’s extreme heat and drought are a stark reminder that periods of plenty could easily be replaced by long-lasting droughts .
The need for ongoing vigilance and action regarding water conservation becomes critically important. As conversations around climate change, sustainability, and environmental policies intensify, every citizen is reminded to engage in responsible practices to ensure the longevity of this vital resource. Failure to act may usher in dire consequences for future generations.
In the context of an ever-changing climate, mobilizing awareness and adapting to new norms will be essential in mitigating the effects of drought and ensuring reliable water supplies. The recent record-setting temperatures serve as a wake-up call that requires collective action towards sustainable resource management.
