The Agencia Estatal de Meteorología expects very high temperatures on 5 September 2026, in La Rioja Saturday. In the Ribera del Ebro highs of up to 41 °C are forecast, particularly in Calahorra. For Logroño up to 39 °C is forecast, while Haro is expected to reach around 38 °C. The agency also expects convective cloud in the afternoon, which could bring local showers or thunderstorms.
Weather-related advisories are in force for parts of the region: according to official forecasts, temperatures of at least 38°C are expected on Saturday in the Ribera del Ebro and the Ibérica Riojana. Winds are forecast to be generally light to moderate. However, thunderstorms may bring brief strong gusts.
Nights will also remain relatively mild. Minimum temperatures are set to rise slightly, limiting overnight cooling. This will favour higher starting temperatures the following day, especially in lower-lying basins and the Ribera del Ebro river valley. Overall, Saturday is expected to be very warm to hot, with relief delayed until the evening.
The assessment is based on current model runs and the latest forecast products from the Agencia Estatal de Meteorología for the affected locations. Short-term adjustments are possible, for example depending on the intensity of afternoon thunderstorm activity. High temperatures were widespread in the region on Friday, adding to the strain on the already heated air near the ground.
The authorities recommend taking basic precautions in these weather conditions: drink plenty of fluids, avoid direct sunlight and physical exertion during the hottest part of the day, keep indoor spaces cool, and look out for particularly vulnerable people such as older people and those with chronic illnesses. Thunderstorms may bring locally strong winds and temporarily reduced visibility.
As things stand, Saturday’s heat is expected to be most intense in the Ribera del Ebro, while slightly lower, but still above-average, maximum temperatures are forecast in the western part of La Rioja. The notices issued by the Agencia Estatal de Meteorología and the regional authorities are authoritative for precise warning levels and updated timings for individual locations.
