Quick Answer
September is genuinely one of the best months to visit Lanzarote. Official climate data from Turismo Lanzarote puts the average temperature at 24.7°C and the average sea temperature at around 23°C, making September one of the warmest months of the year for swimming. That surprises most people. So if you are planning your trip around the sea, you have picked well without even knowing it.
What the Weather Actually Feels Like
Lanzarote September weather does not feel like September. That is the short version. If you are arriving from the UK or Ireland where September means the beginning of acceptable excuses to stay indoors, Lanzarote will feel like a completely different planet.
It is warm, dry and very much still summer. The official average is 24.7°C but the more useful thing to know is that the sun in Lanzarote does not take time off because the light looks soft. The Atlantic breeze makes it feel comfortable even when the UV is doing things you will regret later.
Do not let the wind fool you in the sunscreen department. A breezy September afternoon feels pleasant right until the point where it does not. Take high-factor sun protection, a hat and water whenever you are heading somewhere exposed like Timanfaya or La Geria.
Swimming in September: Better Than You Think
Swimming in Lanzarote in September is one of the better decisions you can make. The sea temperature averages around 23°C according to Turismo Lanzarote, which puts it among the warmest months of the year. What this means practically is that you can spend the morning driving through volcanic landscapes and still finish the day in genuinely warm Atlantic water. You do not have to choose.
Papagayo for calmer water
The Papagayo coves in the south are the obvious choice when you want clear water and relatively sheltered conditions. Turismo Lanzarote describes them as calm water beaches. Sea conditions can always change but Papagayo is as close to a reliable swimming beach as Lanzarote gets. Go early because the car park fills up and the coves are worth arriving for before everyone else has the same idea.
Famara for something completely different
Famara is almost the opposite of Papagayo and worth going to for exactly that reason. It is a huge sweep of beach under the Risco cliffs, consistently windy, with waves and a surf scene that has been there long enough to feel genuinely local. Do not go expecting a sheltered swim. Go for the view, the walk, the cliffs and the feeling that you are looking at the real Atlantic rather than a postcard version of it.
Is It Windy in September?
It can be. Wind is just part of Lanzarote. What makes September interesting is that it sometimes coincides with the beginning of Las Calmas, the period when the summer trade winds start to ease. Turismo Lanzarote notes that this can begin around the start of September in some years and arrive later in others. Do not expect guaranteed calm. What you can reasonably expect is that the stronger summer winds may be starting to soften while the weather and sea are still fully warm.
What to Pack
Summer clothes, swimwear, good sun cream, a hat and comfortable trainers. A light layer for evenings. You do not need to pack for autumn.
The Best Things to Do in September
Timanfaya and the volcanic landscape
Timanfaya is the obvious one and it is obvious for good reason. Book tickets in advance, go early and do not treat the park boundary as the end of the scenery. The roads through central Lanzarote take you through black lava fields even when you are just driving between places.
La Geria
Vines growing in hollows in black volcanic ground, each one protected by a low semicircular stone wall, stretching across slopes that have no business producing wine and somehow do anyway. Stop at a bodega and try the Malvasía if you are not the one driving. Or just drive through and look at it. Both are valid.
Teguise
The old capital of Lanzarote is most famous for its Sunday market but worth visiting on any other day specifically because the market is not there. Without the stalls it becomes easier to notice the cobbled streets, old buildings and the way the town still carries the feeling of somewhere that used to matter quite a lot and knows it.
Leave unplanned time
Over-scheduling Lanzarote is a mistake in any month. In September with this much warmth and light left in the day, it is a particularly unnecessary one.
The September Event Most Visitors Do Not Know About
If your Lanzarote September 2026 dates line up with mid-September, this is one of the most interesting things happening on the island. 15 September 2026 is an official public holiday in Lanzarote and La Graciosa for the Festividad de Nuestra Señora de Los Volcanes. The celebrations centre on Mancha Blanca in Tinajo, where the municipality celebrates Nuestra Señora de Los Dolores, described as the patroness of Lanzarote.
The Romería de Los Dolores, the traditional pilgrimage, begins at 16:30 from the football ground in Tinajo, with the first pilgrims and offerings arriving in Mancha Blanca from 18:00. On Tuesday 15 September the official programme includes a Malú concert at 21:00 and fireworks at 23:30.
This is exactly the kind of thing that does not appear on most September-in-Lanzarote blog posts and exactly the kind of thing that makes a trip feel like more than a week at the beach. Check the Tinajo municipality website for any programme updates closer to the date.
September vs October
Both are excellent. September is fractionally warmer on land at 24.7°C versus 23°C in October. The average sea temperature is around 23°C in both months. Choose September for late-summer energy and the possibility of Los Dolores. Choose October for slightly milder temperatures. Either way it will feel like you have extended summer by several weeks.

To Wrap Up
September gives you the Lanzarote that most people come hoping for: warm weather, warm sea and evenings that feel too good to spend indoors. But the month also gives you La Geria in full growing season, Teguise without the crowds on a Tuesday morning and, if your dates line up, one of the island's oldest and most genuine traditional celebrations in a village most tourists have never heard of.
That is a better version of Lanzarote than the beach alone. September is the right month to find it.
