The Canary Islands in October: what to expect
If September is the best kept month of the Canarian year, October is the most misread. Plenty of people write it off, assuming summer is over. Summer does not end on a date here, it fades, and in October there is a good deal of it left.
The sea is still on your side
This is the part that surprises people. The water reaches its warmest point at the end of summer and cools slowly, far more slowly than the air. In October it is still comfortable for swimming, especially in the south and east of the islands.
For swimming and snorkelling, that means you have not arrived too late. We go into the mechanism in the September guide, because it is the same one: the ocean runs behind the calendar.
What does change is the wind. The trade winds ease off as autumn goes on, and there are more calm sea days in the north, which tends to be choppier in summer.
The rain comes back, and that is not bad news
October is when the first autumn rain can show up. It is worth being precise about what that means, because the word sounds worse than the reality.
This is not continuous rain or weeks of grey. These are episodes, usually short, and spread very unevenly: the north of the high islands gets considerably more than the south, which can go the whole month without a drop. That asymmetry is the rule that governs the archipelago all year, and it decides more about your trip than the month you come in. It is explained in the microclimates guide.
The upside is that the islands turn green. The mid altitude landscapes change colour within weeks, and the summits look sharper once the air clears after a front.
If you do get a wet day, it is not a write off: there is plenty to do, and we collected it in what to do in Tenerife when it rains.
The 12 October holiday
This is the practical detail most people miss. 12 October is a national public holiday, and depending on how it falls, it creates a long weekend that is very noticeable on the islands.
What that means in practice:
Flight and accommodation prices go up around those dates.
More visitors arrive from mainland Spain, not only international ones.
The best known places fill up again for a few days.
If you have any freedom to choose your dates within the month, the first week and the last usually work out better than that middle stretch.
The clocks go back at the end of the month
On the last Sunday in October the clocks go back. It is the Europe wide change, and here it has a very visible effect: from one day to the next it gets dark noticeably earlier.
That matters more than it sounds if you are here to walk or to drive mountain roads. A trail you finished in daylight the week before, you now finish in the dark. It is worth adjusting afternoon plans for the first few days after the change.
There is a reward, though: darkness arrives sooner, and that makes the nights longer. For looking at the sky that is a clear advantage, and on these islands that is no small thing. Where to go is in where to see the stars.
What is on
October is not an empty month in the island calendar. There are patron saint fiestas across several municipalities, some of them significant, plus celebrations that are not religious in origin but have taken firm root, such as the German themed ones in the north of Tenerife.
The warning is the usual one: programmes are published late. If you are coming for something specific, check the dates close to the trip. Our events calendar fills up as they are confirmed.
And one thing does not depend on the calendar at all: whale and dolphin watching runs all year, and with the calmer autumn sea the trips tend to be more comfortable.
What to bring
Sun protection. Still needed, even with softer air.
A light windproof or waterproof layer, especially if you will be in the north or going up to the mid altitudes.
Closed shoes. It is a good month for walking, and trails can be damp.
Swimwear. Do not leave it at home because of the date, you will use it.
So, is it a good month?
Yes, with one condition: that you understand where you are staying. October rewards anyone who picks their area with some thought, and punishes anyone who assumes the weather is the same everywhere on the islands.
If you want warm sea, fewer people than in summer and landscapes starting to green up, it is an excellent month. If you need guaranteed sun every day, the south will give you more certainty than the north. The detail of what to expect in each area through the year is in the weather guide.
