According to data from the State Meteorological Agency (Aemet), which maintains historical records for 65 years, accumulated rainfall in March 2026 was exceptional. At the Roque de Los Muchachos station, 659.4 liters per square meter were recorded throughout the month, with 242.8 falling on a single day, March 24.

Other locations also registered significant figures: San Mateo-Corral de los Juncos with 534.2 liters, San Bartolomé de Tirajana-Las Cuevas with 443.6, and El Paso with 411.6. In total, 45 meteorological stations across the archipelago broke historical rainfall records within a 24-hour period, and 74 surpassed monthly accumulated records.

This phenomenon is primarily attributed to the passage of two storm systems, Regina (between March 2 and 3) and, especially, Therese (from March 17 to 26), which made March not only extremely wet but also very cold. The average temperature was 14.6 degrees Celsius, representing an anomaly of -1.2 degrees compared to the reference average, positioning it as the fourteenth coldest March in the Canary Islands since 1961.

Extreme temperatures were also notable, with thermometers dropping to -5.6 degrees at the Izaña station on March 3, while in Puerto de Mogán, 28.4 degrees were recorded on March 13. Unlike previous years, no tropical nights were reported in the Canary Islands during this month, in contrast to four in 2024 or 277 in 2023. Furthermore, several records for the lowest monthly temperatures were broken in localities such as Agaete (18.1 degrees), Tasarte (17.3), and Las Tirajanas-Tunte (12.9).

Thanks to the intense rainfall from Therese, the current hydrological year, counted from October 2025, is proving to be the eighth wettest in the historical series. The province of Santa Cruz de Tenerife has accumulated 471.9 liters per square meter, and Las Palmas, 264.4.
