Mallorca is facing a turbulent weekend as the Agencia Estatal de Meteorología (Aemet) has issued a series of yellow alerts for the island. Starting Friday, the warnings cover soaring temperatures and rising atmospheric instability. Aemet publishes geographically defined alerts, so conditions and warning levels can vary across the Balearic Islands. Residents and visitors should prepare for intense heat and the risk of sudden storms.
On Friday, heat is the basic concern. Aemet forecasts maximum temperatures of up to 38°C in the island’s interior and northern areas, with the alert in effect from midday until 18:00. Skies will be mostly clear, though some high clouds and developing cumulus are expected. The risk of rain is low, but isolated showers could occur in central Mallorca during the early afternoon. Winds will be light and variable, while coastal breezes will offer little relief from the heat. Nighttime temperatures will remain high, extending the run of tropical or even torrid nights.
Conditions will shift on Saturday. The morning may start with little cloud cover, but the atmosphere will grow increasingly unstable as the day progresses. By early afternoon, Aemet warns of scattered, potentially strong showers and thunderstorms, especially in the island’s interior. The yellow alert for rain and storms is in effect from 13:00 to 17:00, with up to 25 litres per square metre forecast in one hour. That much rain can fall in a short period. Heat will persist despite the showers: a separate yellow alert forecasts temperatures of up to 37°C between 12:00 and 19:00 in the same central areas.
On Sunday, conditions are expected to ease slightly. The day will begin with mostly clear skies, while intervals of mid- and high-level clouds increase during the morning. By afternoon, new convective clouds could bring isolated showers again, mainly in the interior. Temperatures are expected to remain high or fall only slightly, and warm nights will continue. Winds will be light from the east, with coastal breezes developing later in the day.
The alerts follow a broader pattern of instability seen across Spain in recent weeks. For comparison, a recent cold front brought storms and a sharp temperature drop to other regions, underscoring how unpredictable this summer’s weather has been. A separate storm episode in the Balearic Islands in October 2026 showed how quickly rainfall risks can intensify: Aemet warnings reached red in parts of Mallorca, with forecasts of up to 90 litres per square metre in one hour across the south and east, including inland areas. Other parts of the island were under orange warning. Civil Protection issued an ES-Alert in Mallorca, and the Balearic government suspended classes on Mallorca and the two other islands, Ibiza and Formentera, information from Europa Press and elDiario.es. Those later measures concerned a distinct storm episode, not this weekend’s forecast.
In Mallorca, the combination of heat and sudden storms increases the risk of localized flooding and heat-related health issues, especially for vulnerable groups. A yellow alert calls for caution but does not indicate severe danger. Aemet’s warnings are designed to help residents and tourists plan activities and take precautions during periods of heightened risk. Mallorca’s weather in August often changes rapidly, and local authorities typically advise people to monitor official updates closely during alert periods.
