Spain’s weather agency Aemet has issued a warning for Friday, 4 September 2026, in the areas of Altiplano and Vega del Segura of the Region Murcia the yellow warning due to high temperatures. The forecast puts the maximum in both areas at up to 38°C. The warning signals an increased risk to health and wellbeing, particularly during the hottest hours of the day.
Aemet sets warning levels based on regional thresholds. In the Altiplano and Vega del Segura, a yellow warning applies when daytime highs are expected to be around 38°C. It is the lowest of the three levels (yellow, orange and red) under the Plan Meteoalerta and is advisory in nature. Warnings are issued by zone; Aemet specifies the areas affected and the expected period of greatest heat in its notices. They may be adjusted or cancelled at short notice if weather conditions change.
The warning now in force covers two parts of the Region of Murcia that are particularly hot in summer. Heat warnings have already been required there repeatedly in recent weeks, sometimes at a higher level. A yellow warning does not signal an exceptional danger, but points to conditions that, combined with factors such as dry weather and wind, can increase the strain on vulnerable groups and heighten risks such as circulatory problems and wildfires. The classifications guide authorities, emergency services and the public in prevention and operational planning.
health authorities recommend simple protective measures when peaks in temperature are forecast: drink plenty of fluids, avoid direct sunlight and physical exertion during the midday and afternoon hours, wear light clothing and seek out cool spaces. Particular care should be taken with older people, children, pregnant women, people with chronic illnesses and those working outdoors. Neighbours and relatives who may need support should also be checked on.
The assessment is based on Aemet’s current warnings for the Region of Murcia and the thresholds and zones documented in Plan Meteoalerta. Short-term updates to the official forecast will determine how the situation develops. Aemet advises following the notices closely, as the start, end and intensity of warning levels may change depending on how air masses and local effects develop.
