Storm Bruna is expected to bring a period of unsettled weather to parts of Spain, with heavy and persistent rain, thunderstorms, strong winds and rough seas. However, the forecast for Ibiza and Formentera is considerably less severe, with cloudy intervals and only a limited possibility of isolated showers over the weekend of 7 and 8 November.
The Spanish State Meteorological Agency (AEMET) confirmed the arrival of Bruna after the storm was named by Portugal’s meteorological service, IPMA, on 5 November 2026.
In its national weather update published on Friday, 6 November, AEMET warned that a large low-pressure system developing west of the Iberian Peninsula would bring a series of weather fronts across parts of the country. The most significant impacts were expected in the western Peninsula and the Canary Islands.
Where is Storm Bruna expected to have the greatest impact?
AEMET forecast heavy or very heavy showers, potentially persistent and accompanied by thunderstorms, in affected areas. Strong wind gusts and rough sea conditions were also expected, particularly along exposed western coastal areas.
The agency warned of possible local flooding in low-lying areas and rising river levels. It also highlighted the risk of persistent rainfall in areas affected by last summer’s wildfires, where the loss of vegetation can increase vulnerability to runoff and erosion.
The western part of Galicia, areas of the western Central System and parts of the south-western Peninsula were among the areas expected to receive significant rainfall during the episode.
The Canary Islands were also forecast to experience heavy showers and strong winds, with the possibility of particularly intense conditions in mountainous areas.
AEMET stressed that uncertainty remained over the precise development and impact of the weather system, making it important to follow updated forecasts and official weather warnings.
How will Bruna affect Ibiza and Formentera?
Despite the wider national weather warning, the forecast for the Pityusic Islands was much more moderate.
According to the local forecast cited by AEMET on 6 November, Saturday, 7 November, was expected to bring cloudy intervals, with a possibility of occasional, isolated and weak rainfall during the afternoon. Night-time temperatures were forecast to decrease slightly, while daytime temperatures were expected to remain relatively stable. Winds were expected to be generally light.
A similar outlook was given for Sunday, 8 November, with cloudy intervals and a small possibility of isolated light showers. Daytime temperatures could rise slightly, with maximum values potentially reaching around 23°C. Winds were expected to remain light, mainly from the east and south-east.
This means that, although Bruna was expected to influence weather conditions across Spain, Ibiza and Formentera were not forecast to experience the same intense rainfall and wind conditions expected in the areas most exposed to the storm.
Bruna is named by Portugal’s meteorological service
The name Bruna was assigned by Portugal’s IPMA on 5 November and subsequently confirmed in AEMET’s register of high-impact storms and DANA systems for the 2026–2027 season.
It follows Adam, a DANA named by AEMET on 16 October. The two systems are classified differently: Adam was a DANA, while Bruna is a named Atlantic storm.
Residents and visitors in Ibiza are advised to keep checking AEMET’s local forecasts and official weather warnings, as conditions can change as the system develops.
