The month of April 2025 has entered the climatic records of the Canarian archipelago as the Third Rainstock since records began (1961). This is corroborated by the meteorological update released by the State Meteorology Agency (AEMET), which outlines an average of 50.3 litres per square metre accumulated across the islands.
This volume of precipitation signifies a 329% increase compared to the expected figure for this time of year, qualifying the month as Extremely humid according to the 1991-2020 reference series. The pluviometric anomaly was particularly pronounced in Las Palmas Province, where there was a 365% of the average, contrasting with a 314% increase observed in Santa Cruz province, Tenerife.
Much of this remarkable rainfall can be attributed to the passage of several Atlantic fronts over the archipelago, notably the storms ‘Núria’ and ‘Olivier’, with the latter being responsible for the highest daily totals of the month.
On the island of Lanzarote, the Aemet station situated at the Teguise golf course recorded 83 litres per square metre in a single day, closely followed by 81.7 litres
Tenerife records the highest monthly rainfall
Although Lanzarote experienced the most significant daily peaks, it was the island of Tenerife that achieved the highest cumulative monthly total. At the Ravelo station in Sauzal, a remarkable 187.9 litres per square metre fell during April. The station at Llano de los Loros – Monte de las Mercedes, also in Tenerife, recorded 186.6 litres.
These figures affirm an unusually wet weather pattern in the archipelago, significantly exceeding the typical expectations for this spring month.
Despite these record-breaking rains, the Hydrological Year 2024-2025, spanning from October to September, fails to address the accumulated water deficit. According to the latest assessment from Aemet, only 80% of the anticipated rainfall has occurred, leaving the year classified as dry.
This information holds particular significance for sectors such as agriculture and water resource management, which continue to rely on a substantial increase in rainfall in the upcoming months to approach climatic normality.
What about temperatures? Stability with variations
In terms of temperatures, April 2025 has been deemed a “normal” month thermally, with an average of 16.5 degrees Celsius, precisely the reference value for this period. This positions it as the 26th coldest April recorded.
However, this normality was not consistently felt across all islands. In Las Palmas Province, there was a slight thermal surplus, leading Aemet to classify it as a “warm” month, with a positive deviation of 0.3 degrees. Conversely, the month was seen as “cold” in Santa Cruz de Tenerife province, due to a negative deviation of 0.3 degrees.
