Spain is heading into Halloween weekend with contrasting weather conditions, as much of the mainland enjoys settled skies while the Canary Islands prepare for potentially heavy rain. The country has recently enjoyed a spell of unusually warm weather, but conditions are set to vary considerably between regions.

Meteorologist José Miguel Viñas has warned that three Canary Islands could receive more than 50 litres of rain per square metre over the coming days, with showers and thunderstorms expected to develop as a new weather system approaches.

Three Canary Islands face heavy rain

Tenerife, La Palma and El Hierro are the islands to watch, with the developing system potentially bringing substantial rainfall from Saturday, October 31, into the beginning of next week.

The forecast points to increasingly unsettled conditions, with the possibility of locally heavy showers and thunderstorms. A pocket of cold air high in the atmosphere is expected to help trigger the change. Similar weather concerns have recently featured in EWN’s coverage of heavy rain and storms threatening Spain’s Mediterranean coast.

Rainfall of 50mm or more could cause problems in vulnerable locations, particularly where water drains poorly. Residents and holidaymakers should follow local forecasts, especially if planning mountain walks or road journeys. The official weather alerts from the Canary Islands Government provide an additional source of information about declared emergency alerts.

Forecasts can change, however, and the predicted rainfall totals do not mean every part of the three islands will receive the same amount.

Mainland Spain enjoys a warmer Halloween

Conditions across much of mainland Spain are expected to be considerably calmer on Friday, October 30, as high pressure keeps skies largely clear.

Andalucia is set to enjoy some of the warmest temperatures, with Seville forecast to reach 29ºC, while Granada and Huelva could see highs of 27ºC. Madrid is expected to reach around 22ºC.

Rain is more likely along parts of the Mediterranean coast, particularly in Catalonia and the Valencian Community, where isolated showers are possible, making All Saint’s traditions a little wet.

The Balearic Islands face a greater risk of unsettled weather, with showers potentially becoming locally heavy and accompanied by thunderstorms around the middle of Friday.

Strong winds and a warning for travellers

Drivers and residents around the Strait of Gibraltar should also watch for strong easterly winds, with particularly powerful gusts possible during the early hours. Morning mist and fog could affect parts of Galicia and the Cantabrian coast, potentially reducing visibility on the roads.

Although much of the country looks set for a pleasant end to October, conditions will vary considerably between regions.

Spain is set for another taste of summer this Sunday and Monday, October 25 and 26, with temperatures expected to climb above 25°C in several parts of the country. From the Costa Blanca to the Costa del Sol, residents and holidaymakers could enjoy a return to warmer weather just days before November.

The warmer conditions follow a brief spell of cooler weather across parts of Spain. But the autumn chill may not last long, particularly in the south, where temperatures could remain unusually high throughout the coming week.

According to meteorologist Duncan Wingen of Meteored, a subtropical air mass is expected to move over Spain from Sunday, October 25, pushing temperatures upwards. The warm spell, known locally as veroño, or Indian summer, could last into early November in some areas.

The warmest conditions are expected from Monday, October 26, although the outlook will vary considerably between northern and southern Spain.

Where temperatures will rise above 25C on Sunday and Monday

Temperatures are expected to rise across much of Spain from Sunday, October 25, with the warm spell becoming more noticeable on Monday, October 26.

Southern Spain is likely to experience some of the highest readings, particularly in Andalusia, where temperatures could climb above 25°C. As the warm spell develops, parts of the Guadalquivir Valley and southern Canary Islands could eventually see highs of 30°C to 32°C.

Further inland, Extremadura and Castilla-La Mancha are also likely to see a prolonged period of mild to warm weather, with daytime highs potentially remaining above 25°C until the end of October.

The warm spell will be driven by a subtropical ridge, an area of relatively high atmospheric pressure accompanied by warmer air at higher levels of the atmosphere.

Monday is forecast to bring the first peak in daytime temperatures, before a change in atmospheric conditions affects parts of northern Spain later in the week.

The latest outlook is also supported by Spain’s national weather agency, AEMET, which expects generally stable conditions between October 26 and November 1.

AEMET predicts maximum temperatures above 20°C across large areas of Spain, with readings exceeding 25°C in much of the southern mainland and some Mediterranean locations.

However, the agency also anticipates a temporary drop in temperatures between Tuesday and Wednesday, meaning the warmer conditions will not affect every region equally.

Which Spanish regions will stay above 25C until November?

For residents and visitors along Spain’s Mediterranean coast, the most noticeable feature of the forecast is how long the warmer weather could last.

According to Meteored, Alicante, Murcia, Malaga and Almeria could experience temperatures above 25°C for at least a week, potentially continuing until the final days of October.

This means parts of the Costa Blanca and Costa del Sol may continue enjoying pleasantly warm afternoons at a time when many European destinations are already experiencing much colder conditions.

In Andalusia, Seville and Cordoba are also expected to remain particularly warm, while Badajoz in Extremadura could see similarly persistent temperatures.

The Canary Islands are another area where the warmer conditions are likely to last, with some southern locations forecast to approach or exceed 30°C.

However, the picture will be different further north.

Meteored expects a trough of lower atmospheric pressure to move across northern Spain around Wednesday and Thursday, October 28 and 29. This could bring a noticeable reduction in daytime temperatures to the Cantabrian regions, inland Galicia and Castilla y Leon.

By Thursday, maximum temperatures in parts of Catalonia and Aragon are expected to settle between 20°C and 24°C.

The trough is forecast to weaken as it moves across the Peninsula, limiting its impact on southern regions.

As a result, the southwest and Canary Islands could continue recording temperatures between 25°C and 30°C even as northern Spain becomes cooler.

Despite the summer-like afternoons, residents should not expect equally warm nights. Meteored warns that overnight temperatures could fall below 15°C across much of inland Spain, with some areas of the central plateau dropping below 10°C.

The contrast between warm afternoons and chilly mornings could be particularly noticeable for anyone heading out early or spending time outdoors after sunset.

When will autumn weather return to Spain?

The biggest question is whether Spain’s Indian summer will finally end as November begins.

Forecasters suggest the warmer conditions could extend beyond October 31, although there is increasing uncertainty about how long they will last.

Meteored’s analysis of the European weather model indicates that temperatures during the week from October 26 to November 2 could be between 1°C and 3°C above average across parts of inland Spain, the Andalusian coast, the southeastern coastline and the Canary Islands.

A more widespread fall in temperatures could arrive during the first week of November if another trough develops over the Peninsula.

However, Meteored notes that this scenario has become less pronounced in recent model updates, making the exact timing of any significant cooling uncertain.

AEMET’s longer-range outlook offers a similar picture, while highlighting important regional differences.

For the week of November 2 to 8, the agency suggests temperatures could return closer to seasonal averages across much of northern and eastern Spain, as well as the Balearic Islands.

Meanwhile, southwestern Spain and the Canary Islands may continue experiencing temperatures above the seasonal norm.

The agency also identifies the possibility of more humid easterly winds bringing rain to parts of the Mediterranean coast, although confidence in these longer-range predictions remains limited.

For anyone living in Spain or planning a late-October getaway, Sunday and Monday could bring a welcome return to warmer afternoons, especially in the south and along the Mediterranean coast.

And the good weather may not end there. Some areas could continue enjoying temperatures above 25°C into the final days of October, although cooler conditions are expected further north.

With November approaching, it remains unclear exactly when the warmer spell will end. For now, residents and visitors can check the latest local forecasts to see how long the sunshine is likely to last.
