What changes on Friday in the south of Tenerife?

Cloud thickens in the south, the west and the interior from noon. AEMET also expects a few showers there.

The morning is therefore the better time for the beach or an outing. That is our reading of the forecast, because AEMET gives no exact start for the rain.

The north gets the opposite, with rain over much of the day. It is light and patchy, and it comes and goes.

Temperatures dip slightly, mainly in the mid-altitude areas of the island (medianías). For Santa Cruz de Tenerife, AEMET gives a minimum of 21 degrees and a maximum of 25 degrees.

The forecast gives no separate figure for the south coast. If you plan a hire car trip or a hike, check the latest AEMET forecast before you set off.

What are the wind and sea like around Tenerife?

The wind is light from the north on Friday. Sea breezes join it on the north and west coasts.

On the high ground around Teide, the wind turns west, with weak spells. The forecast mentions no strong gusts.

At sea, the north wind stays at force 2 to 4, with spells of force 5 possible in the south-east and west until the afternoon. The sea is slight to moderate (marejadilla or marejada) and eases during the day.

Waves of three to four metres roll in on a north-westerly swell, falling to about two metres. AEMET does not say how this affects individual beaches.

What can we expect on Saturday and Sunday?

Saturday 14 November stays mostly stable, with light rain possible in the north. In the second half of the day, cloud increases in the south and the interior.

AEMET considers rain more likely on Tenerife than on the other islands. The wind stays light from the north, and temperatures change little or dip slightly.

Sunday 15 November brings only a slight chance of light rain on the mountains of the higher islands. Cloud can build in the afternoon in the interior with a southerly aspect, where AEMET rates rain as somewhat more likely.

The north wind picks up to light to moderate, and no big temperature swings are expected. No warning is known for the weekend.

Why does this forecast matter after a stormy week?

The week before was unsettled. For the night to 8 November, AEMET had forecast about 120 litres per square metre on Tenerife, triggered by the low Bruna.

For 11 November, the agency expected 80 to 120 litres per square metre on La Palma and Tenerife, locally more than 150. These were forecasts, not measured amounts.

The Canary Islands government declared a wind alert for the whole archipelago from 18:00 on 10 November. Gusts of up to 110 kilometres per hour were forecast for Tenerife.

The good news: that alert ended at 18:57 on 12 November, after the low Charles passed. All that is left for visitors and residents is cloud and light rain.

Who issues warnings, and what applies if it turns serious again?

AEMET issues the coloured warnings, yellow, orange and red, which measure the weather phenomenon. The civil protection signal, meaning pre-alert or alert, comes from the emergencies directorate general of the Canary Islands government under the PEFMA emergency plan.

An island can therefore have an AEMET warning without an alert in force. The Cabildo de Tenerife (island government) also activates the island plan PEIN.

In an alert, the Cabildo and the Canary Islands government advise staying away from ravines (barrancos) and flood-prone areas. They also ask people to avoid unnecessary journeys, stay off closed footpaths and secure objects on balconies.

That advice mattered on 1 November, when the government declared a rain alert for the wider Tenerife area. In the March alert, the Cabildo closed the Teno road TF-445 and the access routes to Teide National Park, among others.

AEMET updates the island forecasts daily. For the period after Sunday 15 November, no forecast was available as of Friday.
