What changes for visitors and residents on Tenerife?
On Wednesday 4 November, the Aemet expects showers that can turn heavy locally and bring storms. They mainly affect the inland areas of the islands with mountains, plus Lanzarote and Fuerteventura.
From Thursday 5 November, the rain eases. Showers lose strength and become less likely, and the Aemet expects no significant weather events that day.
On Friday 6 November, it turns warmer as the trend towards higher temperatures continues. The Aemet expects a slight to moderate rise, clearest in daytime highs inland.
If you plan a hike or a drive inland on Wednesday, move it to Thursday. The report names no warning for southern Tenerife alone, and it is unclear whether a formal warning level applies to Tenerife on 4 November.
What does Wednesday look like on Tenerife in detail?
On Wednesday morning, the Aemet says patches of cloud drift through, and cloud builds from midday. After that, aguaceros (heavy downpours) are likely in the mountain areas, storms included.
In the evening, showers may also reach the coast, several Aemet island forecasts note. The north-east, north and east are most likely to get them.
Temperatures barely change on Wednesday or fall slightly.
For comparison, the service forecasts 21 to 26 degrees for Las Palmas on Gran Canaria and 15 to 20 degrees for Valverde on El Hierro. The wind is light and variable, mostly a breeze.
One island forecast, which the report does not clearly assign to an island, puts the snow level above 2,800 metres, and it may dip slightly at times. If you head to the high mountains, check the forecast at aemet.es.
What happens on Thursday and Friday?
On Thursday 5 November, the Aemet says it stays cloudy, with cloud building inland on the mountainous islands. Isolated light to moderate rain is possible there, most likely on the northern and eastern slopes.
Temperatures stay the same on Thursday or rise slightly. The wind is light from the south on the western islands and moderate from the south-west on Tenerife's central summits.
On Friday 6 November, the Aemet expects high cloud and growing cloud inland on the western islands. On La Palma and Tenerife, the chance of light, occasional rain stays low.
The Aemet did not say in this report how far temperatures will rise. Whether a calima (dust-laden air from the Sahara) or a heat warning follows is not confirmed.
What did the authorities advise in earlier storms?
On 22 October, a warning applied on the western islands. Orange covered the east of La Palma, La Gomera and El Hierro, and yellow covered the west of La Palma and all of Tenerife.
The forecast spoke of up to 30 litres per square metre in an hour and up to 100 litres in twelve hours. The advice then was to check roofs and drains and not to park in the bed of a barranco (ravine).
People were told not to cross flooded spots, to skip unnecessary trips, and to keep a battery radio and emergency supplies. The authorities have so far issued no separate advice for 4 November.
It could not be established whether the Cabildo de Tenerife (island government) or the 112 Canarias emergency service has taken measures for that day. The rainfall totals for 4 November are not yet available either.
What did the Aemet say about autumn, and how does this fit?
For September to November, the Aemet put the chance of a warmer-than-average autumn in the Canaries at 60 to 70%. It saw a colder autumn than usual as possible at only around 10%.
On rain, the Aemet says the signal points mainly to a drier-than-normal scenario, though the uncertainty is greater here. The outlook gives 40% for below-average rainfall.
Warm seasons do not rule out cold spells, the service added. For 12 October to 1 November, it had forecast a warmer-than-usual spell with little rain.
October 2023 shows how much autumns differ. The Aemet put the mean temperature at 23.8 degrees, the warmest October since 1961, with a 16-day heatwave from 2 to 17 October.
In autumn 2025, October to December was wetter than normal. On the wettest day, 14 December, the Aemet recorded 150 litres per square metre, plus more than 3,000 lightning strikes and gusts around 100 kilometres per hour.
A single rainy day therefore says little about the winter. That is our assessment, not a statement from the Aemet.
What remains open, and where is the current forecast?
The report names no Aemet spokesperson and gives no figure for the coming rise in temperature. It also does not say how long the warmer spell will last.
The papers do not say when the Aemet will update its forecast. The current version for the Canaries is on the service's website, aemet.es.
For Tenerife, it pays to check there on Wednesday and Friday. On Wednesday, possible storms matter, and on Friday, the expected rise in temperature inland.
