Severe Weather Warning for Mallorca: What Passengers and Holidaymakers Need to Know for 9 September
Tuesday, September 8th, 2026
A significant shift in the weather is expected across Mallorca tomorrow, Wednesday 9 September 2026. Following a period of extreme heat, a cold front is set to reach the Balearic island. Spain’s meteorological agency, AEMET, has issued an orange weather warning for the entire island.
Travellers and holidaymakers should prepare for potential severe weather and take appropriate precautions, particularly when planning outdoor activities or travelling to and from Palma de Mallorca Airport.
Wednesday’s Weather: Torrential Rain, Gales, and Hail
Weather conditions across Mallorca will deteriorate noticeably on Wednesday. While the day may start calmly in some areas with occasional early fog patches, thick cloud will quickly build up during the morning.
- Rainfall: The warning is in place between 10:00 am and approximately 9:00 pm. Extreme local downpours are expected, with up to 40 litres of rain per square metre falling in a single hour.
- Wind and Gales: Whilst a moderate south-westerly wind will blow in the morning, it will veer north to north-easterly during the day and pick up significantly. Gusts could exceed 90 km/h, generating waves of up to four metres along the coast.
- Thunderstorms and Hail: Rain showers will be accompanied in places by heavy thunderstorms and potential hail.
- Temperature Drop: The passage of the front will bring a long-awaited cool-down. Maximum temperatures will drop by more than six degrees, settling between 29 °C and 32 °C.
The storm is expected to ease from Thursday onwards. Temperatures will drop further to around 27 °C to 30 °C, though coastal waters may remain rough for some time.
Key Safety Advice for Holidaymakers
If you are currently on the island, you should adjust your plans according to the weather conditions:
- Avoid beaches: Under no circumstances should you swim in the sea on Wednesday. Thunderstorms, high waves and strong currents pose a life-threatening risk. Coastal promenades should also be avoided.
- Minimise outdoor time: Authorities advise staying indoors where possible while the severe weather passes and avoiding non-essential journeys.
Impact on Flights at Palma Airport (PMI)
Passengers booked on flights to or from Palma de Mallorca on 9 September should be prepared for potential delays. Severe weather events of this scale tend to have a direct impact on air traffic.
How Severe Weather Disrupts Airport Operations
- Safety margins: Heavy rain, low cloud, and thunderstorms with hail significantly impair visibility. To ensure safety, air traffic control increases the time and distance between planes taking off and landing, leading to capacity bottlenecks on the runways.
- Wind shear and gusts: Strong, sudden wind shifts on final approach can present major challenges. If crosswinds are too severe or unpredictable, landings may need to be aborted or approaches delayed.
- Ground safety risks: Whenever thunderstorms pass directly over the airport grounds, ground operations must be temporarily suspended for staff safety. Aircraft refuelling, luggage loading and unloading, and apron boarding cannot take place when there is a risk of lightning strikes.
- Airspace delays: Because the weather problems affect not only the Balearics but often entire flight corridors, knock-on effects occur. Late-arriving aircraft create cascading delays throughout the daily flight schedule.
Advice for Passengers
Here are a few practical tips to help you navigate the weather disruptions as smoothly as possible:
- Check your flight status in advance: Check your airline’s app or website to stay updated on the status of your flight.
- Arrive at the airport for your originally scheduled time: Even if your flight is delayed, please travel to the airport for your original departure time and adhere to standard check-in deadlines. Airlines will try to take advantage of sudden new departure slots or deploy replacement aircraft; arriving late at the gate risks missing your flight. Only adjust your arrival time if explicitly instructed to do so by your airline.
- Allow extra travel time: Torrential rain on Mallorca’s roads can quickly lead to disruptions or aquaplaning. Allow plenty of extra time for your journey to Palma Airport so you arrive at the terminal stress-free.
- Stay informed at the terminal: If you face a wait at the airport, make yourself comfortable in the terminal. Pay close attention to public announcements and display boards: airport staff will be doing everything possible to keep you updated and get you safely to your destination.
