The Canary Islands are bracing for potentially heavy rain and thunderstorms over the Halloween weekend, while mainland Spain enjoys warmer and more settled conditions. Meteorologists warn that Tenerife, La Palma, and El Hierro could experience significant rainfall, with more than 50 millimetres expected per square metre between Saturday, October 31, and early next week.
This wet weather is attributed to an approaching system combined with cold air at higher altitudes, which is likely to trigger showers and thunderstorms across the islands. The heavy rainfall could lead to problems in areas with poor drainage and pose risks for travelers in mountainous regions. Residents and visitors are advised to stay informed through local weather forecasts and heed official alerts. However, rain levels may vary significantly across the islands.
In contrast, much of mainland Spain is set to enjoy calm weather due to high pressure maintaining largely clear skies. Andalucia is expected to experience some of the highest temperatures, with Seville potentially reaching 29°C, while Granada and Huelva could see highs around 27°C. Madrid is anticipated to reach approximately 22°C.
Some Mediterranean areas, such as Catalonia and the Valencian Community, might experience isolated showers, while the Balearic Islands face a greater chance of unsettled weather, with local heavy rain and thunderstorms possible.
Potential travel disruptions could arise from strong easterly winds around the Strait of Gibraltar, with powerful gusts occurring during the early morning hours. Additionally, morning fog and mist might reduce visibility in parts of Galicia and along Spain’s Cantabrian coast.
Although the mainland is expected to enjoy pleasant conditions at the end of October, significant regional differences highlight the importance of checking the latest forecasts and official weather warnings before making travel plans or engaging in outdoor activities.
