The Canaries are not eight versions of the same island. Five of them rise above 1,000 metres and manufacture their own cloud cover: they have a green north and a dry south, and what you are really choosing is no longer the island but the slope. Two stay low: one sky everywhere, and wind. On top of that comes a constraint the map hides — 6 to 7 hours of sea separate the eastern group from the western one. Here is how to decide on those two criteria, and what changes on Mount Teide in 2026.

Sorting islands by atmosphere does not survive the first afternoon
Open ten Canary Islands comparisons and you will read the same ranking ten times. Tenerife to do everything, Lanzarote for art and volcanoes, Fuerteventura for beaches, La Gomera for nature, Gran Canaria for variety. That ranking is not wrong. It is simply unable to predict your days, because it describes the character of the islands and never the two mechanisms that actually decide a holiday here: altitude and distance at sea.
Both can be measured before you leave, and between them they explain almost everything that surprises visitors on arrival: why it rains above your hotel while the beach is in full sun, why the wind never drops in the east, why the island next door on the map takes a whole day to reach.
So this article turns the problem around. You choose a climate regime and a position in the network first; the character of the island comes second. It is less romantic, and it is the only criterion you can check from home.
Relief manufactures the climate, and the threshold sits near a thousand metres
The trade winds arrive from the north-east, loaded with moisture from the Atlantic. When they meet an island that is high enough, the air is forced upwards, cools and condenses: a cloud layer settles in, and in the Canaries it settles between 1,000 and 2,000 metres. It is the same phenomenon that gave La Palma its observatories: they are built above the layer, where the sky is clear almost every night.
The consequence is mechanical. An island that passes that threshold has two climates — a windward northern slope, cooler, greener, often overcast; a leeward southern slope, dry and sunny. An island that stays below it has only one, the same everywhere. This is not a brochure nuance: it is the difference between a week spent looking for the sun and a week where the sun is a given.
| Island | Highest point | Two climates? | What it changes on the ground |
|---|---|---|---|
| Tenerife | 3,718 m | Yes | The widest gap in the archipelago: green cloudy north, dry sunny south, 3,700 m in between |
| La Palma | 2,426 m | Yes | Very wet north and east, clearer west; remarkable skies above the cloud layer |
| Gran Canaria | 1,949 m | Yes | A “miniature continent”: dunes in the south, forest in the middle, mist in the north |
| El Hierro | 1,501 m | Yes | Small but high: the northern slope stays green all year |
| La Gomera | 1,487 m | Yes | Permanent laurel forest up top, dry sunny coasts in the south |
| Fuerteventura | 810 m | No | One climate only, dry and bright everywhere; the wind varies, the sky does not |
| Lanzarote | 671 m | No | One climate only, the driest in the archipelago; no relief to hold a cloud back |
Read the right-hand column rather than the middle one. Teide peaks at 3,718 metres, which gives Tenerife the widest internal gap in the archipelago — you can drive from a dripping forest to a sun-baked beach in an hour. Lanzarote tops out at 671 metres: nothing on that island is tall enough to hold a cloud.
So the real question is not "which island" but "which slope"
Here is the practical consequence, and it is the one that should settle your booking. On five of the eight islands, the slope matters more than the island's name. Two travellers spending the same week on Tenerife, one in Puerto de la Cruz in the north, the other in Costa Adeje in the south, will not describe the same trip — and both will be right.
That does not mean you should pick the south. The north of Tenerife and of La Palma hold the finest landscapes of the archipelago, and the climate there is mild all year. It means you should choose knowing what you are choosing: a beach week belongs in the south, a hiking-and-villages week in the north, and a week that wants both belongs between the two, on the understanding that you will drive.
Which is exactly where the car question is settled. On a two-climate island a car is not a comfort: it is what allows you to go and find the sun on the other side when your slope is shut in, something bus timetables will not do on demand. On the larger islands rental mostly runs through local agencies, and in high season it pays to book early: an island's fleet is finite. On Lanzarote and Fuerteventura, by contrast, a car gets you to remote beaches — it no longer arbitrates anything, since the sky is identical everywhere.
In the east, the wind: what it gives, what it costs
Lanzarote and Fuerteventura are the two low islands of the archipelago, and that makes them the driest and the brightest. For anyone chasing winter sun without a lottery, they are the best bet in Europe: no cloud layer to get round, no slope to arbitrate.
The trade-off has a name, and it deserves to be said plainly: the wind does not drop. Nothing on these islands stops it. That is what makes Fuerteventura a major kitesurfing and windsurfing destination, and it is the same thing that puts sand back on your towel on a March afternoon. It is neither a flaw nor a detail: it is the island's climate, and you have to want it.
Conversely, the high islands shelter their southern face. The bulk of Teide cuts the trade winds, and southern Tenerife is markedly calmer than the eastern coasts. Same mechanism, seen from the other side: what gives the eastern group its light and its swell gives the high islands their sheltered south.
Moving between islands: the map lies about distances
On a map the Canaries form an even string of islands. In the timetables they are two separate systems. In the east, Lanzarote and Fuerteventura sit 25 to 35 minutes apart: you go for the day. In the west, Tenerife and La Gomera are 50 minutes apart, with around 6 sailings a day. Between the two groups, though, from Arrecife to Las Palmas, allow 6 to 7 hours at sea.
| Group | Islands | Shortest internal hop | To the rest of the archipelago |
|---|---|---|---|
| Eastern | Lanzarote, Fuerteventura, La Graciosa | 25–35 min | 2 hrs by sea to Gran Canaria (Morro Jable) — 6 to 7 hrs from Arrecife to Las Palmas |
| Hinge | Gran Canaria | — | Connected to both groups: 80 min from Tenerife, 2 hrs from Fuerteventura |
| Western | Tenerife, La Gomera, La Palma, El Hierro | 50 min | 80 min to Gran Canaria, up to 8 sailings a day |
Gran Canaria is the hinge: linked to Tenerife in 80 minutes with up to 8 crossings a day, and to Fuerteventura in 2 hours to Morro Jable. It is the only island touching both halves of the archipelago without flying.
Air traffic tells the same story, more sharply. In 2025 the eight Canary airports handled 54,753,915 passengers, 58.7 % of them on international flights. But the split is very uneven: 15,826,553 at Gran Canaria and 21,144,655 across Tenerife's two airports, against 128,341 at La Gomera — 123 times fewer. In plain terms: you cannot land everywhere. La Gomera and El Hierro are reached from their hub, never directly from Europe.
One last link, routinely underestimated: the airport you land at is not near your coast. Tenerife has two, one in the south and one in the north, about an hour's drive apart — and the flight that suits you does not necessarily land on the right side. If your accommodation is on the opposite coast, or if you connect to a boat the same day, a transfer booked in advance removes the part of the problem that depends on you: hunting for a taxi, a desk or the right quay at the worst hour of the day.
What changes on Teide in 2026, and the guidebooks have not caught up
If the volcano is what tilts you towards Tenerife, this paragraph is for you. Teide National Park is moving to compulsory advance booking, with an eco-tax for non-residents and visitors spread across time slots. The Cabildo of Tenerife has confirmed it for 2026.
The tightest constraint concerns trail no. 10, "Telesforo Bravo", the one that climbs to the crater from the upper cable-car station: it is capped at 300 people a day, in groups of 50. Trail no. 7, "Montaña Blanca – Rambleta", is affected too. Tenerife residents are exempt, other Canary residents pay a token amount, and access is free below the age of fourteen. Climbing without authorisation carries an announced fine of up to €600.
One clarification that will save you a bad surprise and a pointless purchase. Summit permits are issued only through the official Tenerife ON platform: no reseller can supply one. The exact eco-tax amounts, for their part, were not yet settled on 11 September 2026 — announcements quote different ranges depending on the trail and the services included. Check them on the official portal before building a day around it, and book early: 300 places a day on the crater trail, on an island handling more than twenty million air passengers a year, is a bottleneck, not a formality.
None of this rules the volcano out — the cable car, the caldera trails and the Cañadas road remain open, and the landscape alone justifies the trip up to 3,718 metres. It simply moves Teide out of the "we'll see when we get there" category and into the "book before you leave" one.
How many islands in a week: two, and often just one
Let us do the arithmetic honestly. Every island change costs half a day: the room is released late morning, you have to reach the port, board, cross, then find the next place and settle in. Over seven nights, two changes consume a full day.
The rule that follows fits in one sentence: two islands maximum, and in the same group. Lanzarote and Fuerteventura are the natural eastern pair; Tenerife and La Gomera the western one; Gran Canaria pairs with either. What does not work in a week is crossing the archipelago end to end — 6 to 7 hours at sea, or a domestic flight with its two transfers, out of a week that only has seven days.
And since the question always comes up: La Graciosa, the archipelago's eighth inhabited island since 26 June 2,018, 29 km² and around 750 inhabitants, attached to the municipality of Teguise. You reach it by boat from northern Lanzarote, and it has neither tourist cars nor tarmac roads. It makes a magnificent day out — and it is the perfect example of what never goes last before a flight home: it is served by a small boat, and small boats stop before big ones when the wind gets up.
So which one? Four answers, depending on what matters to you
You are after guaranteed winter sun. Lanzarote or Fuerteventura, without hesitation: no cloud layer, no slope to arbitrate, the same sky everywhere. Accept the wind — it is part of the deal, and it is what makes these islands so luminous.
You want everything on one island. Tenerife or Gran Canaria. They are the only two that gather volcano, forest, dunes and beaches within an hour's drive, and the two best connected to the rest of the archipelago. Choose your slope deliberately, and take a car.
You are coming to walk. La Palma and La Gomera, and this is where the cloud layer becomes an asset: it is what manufactures those forests. Plan to arrive via Tenerife for La Gomera, and know that you will be on a branch island — keep a spare day before the flight home.
You still cannot decide. Ask yourself the single question this article boils down to: do you want an island with two climates, or an island with one? Everything else — atmosphere, museums, beaches — is decided afterwards and can be changed en route. The climate regime and the position in the network are fixed the day you book your flight.
