High Temperatures Persist in La Rioja Under AEMET Yellow Alert
The Spanish State Meteorological Agency (AEMET) has maintained a yellow-level weather alert for high temperatures across the La Rioja region, as thermometers in the Ebro Valley continue to hover near the 36°C mark. Rincón de Soto recorded the highest temperatures in the region, reaching 35.8°C on Saturday, according to data from the Government of La Rioja agroclimatic network.
Where are the highest temperatures in La Rioja?
The heat is concentrated primarily in the Ebro Valley, where multiple municipalities reported temperatures exceeding 34°C. Following Rincón de Soto’s peak, Alfaro registered 35.4°C, while Calahorra reached 34.9°C. Other locations in the eastern part of the region, including Autol, Aldeanueva de Ebro, and Agoncillo, maintained a consistent heat level of 34.8°C. Data provided by SOS Rioja indicates that even areas typically cooler, such as Haro and Logroño, recorded highs of 34.7°C and 34.6°C, respectively.
How does altitude affect local temperatures?
Topography remains the primary factor for those seeking relief from the heat. While the valley floor experiences sustained high temperatures, mountainous zones show a significant variance. According to regional meteorological records, Moncalvillo measured 25.1°C, and Pazuengos remained at 27.0°C. This temperature gap of nearly 10 degrees highlights the protective effect of higher elevation during sustained heatwaves in the region.

What is the forecast for the coming days?
The AEMET yellow alert is currently scheduled to remain in effect until 21:00 on Sunday. Meteorologists expect maximum temperatures to stay within the 35°C to 36°C range across the ribera. Residents are advised to monitor official updates through the AEMET portal or local civil protection channels, as high-temperature alerts are issued when heat poses a potential risk to health or outdoor activities.
