Ibiza and Formentera are under orange alert for torrential rain and storms. The warnings coincide with the first day of school. Authorities expect wind gusts over 90 km/h and possible hail.
Ibiza and Formentera are set for a rough start to the school year as the Agencia Estatal de Meteorología (Aemet) has issued an orange alert for violent storms, heavy rain, and wind gusts over 90 km/h. The highest risk is expected on Wednesday between 10:00 and 21:00, when up to 40 litres of rain per square metre could fall in just one hour. There is a 40–70% chance of severe downpours and hail. Emergencias 112 Baleares reports that this orange alert covers the entire Balearic archipelago, with the storm linked to a weather front moving in from the Iberian Peninsula.
After 21:00, the alert drops to yellow, but the risk of intense rainfall—up to 30 litres per square metre in an hour—remains until midnight. Coastal conditions add to the concerns: Aemet has a yellow warning in place all day, with northern and northeastern winds reaching 60 km/h and waves up to four metres. The chance of rain rises from 35% in the early morning to 80% by late afternoon, then drops to 50% at night. Temperatures are expected to swing between 23 and 32 degrees. This comes after a period of yellow alert for extreme heat, with Ibiza recently nearing 40°C, marking a sharp shift from heat to unstable weather, according to Periodico de Ibiza.
"The official forecast notes that a temperature drop of around 10°C is expected during the storm episode, with rough sea conditions likely to persist until Thursday."

Thursday brings little relief. The unsettled weather continues into the morning, just as students return to classrooms across the Pitiusas. From midnight to 7:59, yellow alerts for rain and storms remain, with a renewed risk of 30 litres per square metre in an hour and a 40–70% chance of more downpours. Coastal warnings stay in effect until midday, with winds up to 50 km/h and waves reaching three metres. Rain probability is high at 70% for the first half of the day, dropping to 15% in the afternoon as conditions slowly improve. Temperatures should range from 20 to 29 degrees. Aemet warns that marine hazards will last longer than the heaviest rain, so caution is still needed for coastal activities.
The forecast shows some improvement by the weekend, but more showers are possible. On Friday, the chance of rain is 45% in the morning and 35% in the afternoon, with temperatures between 20 and 29 degrees. Saturday keeps a 45% risk of rain and slightly warmer highs. Sunday finally looks calmer, with only a 15% chance of rain and temperatures steady between 21 and 30 degrees.
"The severe weather episode is described by primary sources as short but intense, with the most significant risks concentrated on Wednesday. However, the marine warnings are expected to remain in place longer than the heaviest rainfall, potentially affecting ferry schedules and coastal transport until at least Thursday."

These warnings are part of a wider pattern of severe weather along Spain’s coast. Similar alerts were recently issued in Galicia, where storms and heavy rain disrupted daily life, as reported earlier. For the Balearics, the timing of these storms creates extra challenges for schools, families, and local authorities, who now have to adjust plans just as the school year begins.
Aemet’s warnings are clear and urgent. The overlap of severe weather with the start of classes highlights how exposed local infrastructure can be and the need for quick response. While the forecast points to better weather by the weekend, the timing of these storms shows how unpredictable conditions are now a regular part of life in Spain’s island communities.
