For Wednesday, 19 August 2026, the AEMET in La Rioja has activated a yellow warning for high temperatures. The areas affected are the Ribera del Ebro and the Ibérica. Highs of around 38 degrees are expected in the lowlands, with local peaks close to 40 degrees in the valleys not ruled out. The assessment is based on the forecast published on Tuesday.
The forecast calls for mostly little cloud in the morning, with cloud increasing later. In the afternoon, the chance of showers will rise, particularly over the mountain range; thunderstorms are possible locally in the afternoon. Winds will be mainly light to moderate from the north to north-west.
For central locations in the region, the forecast gives the following ranges: in Calahorra around 19 degrees early in the day and up to 38 degrees in the afternoon are expected; in Haro around 18 to 37 degrees; and in Logroño around 19 to 38 degrees. Overall, temperatures will rise slightly to moderately compared with the previous day, particularly overnight lows.
A yellow warning signals potentially dangerous conditions, especially for vulnerable groups. AEMET continually updates the sub-zones and time periods covered by the warning; short-notice changes are possible. On hot days, health services generally recommend avoiding physical exertion during the hottest hours, drinking enough and seeking out cool indoor spaces.
Across the country, the current heatwave varies in intensity from region to region. At the same time, higher warning levels are in force in some parts of Spain, including the Comunitat Valenciana. In La Rioja, the focus on Wednesday remains on high daytime temperatures in the Ribera del Ebro and the areas of the Ibérica favoured by local topography. Further developments and any easing of conditions will depend on the short-term weather situation and will be clarified in new AEMET updates.
The figures and warning levels given here are taken from the official AEMET forecast and regional reports for Wednesday. Statements on the intensity and geographical extent of the heat refer to the planning outlook as of Tuesday and may be adjusted as newer data become available.
