Lanzarote in September: Weather, Crowds and What to Do

September in Lanzarote at a Glance

Think of September as late summer that has quietly shed its crowds. The beaches empty out once Spanish and British schools return, yet the sea stays warm enough for long swims and the days remain reliably sunny. It suits travellers who want heat but not queues, and who are happy to structure the day around the strongest sun.

The trade-off is residual heat. August is the island's hottest month and September only eases off slightly, so midday hiking or cycling is still a poor idea. If you want a full day of walking, aim for the coast or start before the sun is high; if you want lazy afternoons, September delivers.

What the Weather Is Like in September

Daytime averages of about 29°C and night-time averages of about 21°C are the working figures for the month. Expect the warmest hours between late morning and mid-afternoon, and a coastal breeze that makes the heat feel gentler than the number suggests. Evenings are comfortable rather than chilly, so a light layer is enough for dinner outdoors.

A second set of September climate figures puts the range at roughly 21°C to 28°C, which aligns closely with the averages above. Treat these as typical rather than guaranteed: a hot spell can push the mercury higher, and the wind can make a sunny day feel cooler on exposed ground.

Inland and higher ground runs a little milder than the southern resort coast, which is why a volcano visit can feel less punishing than the beach car park. Carry water on any excursion and wear a hat; the dry air makes dehydration easy to miss.

Rainfall, Sunshine and Humidity in September

September climate data for the island gives rainfall of up to about 10mm for the month, alongside roughly nine hours of sunshine a day and humidity near 70 per cent. In practice that means rain is unlikely to interrupt a holiday, and a wet day is the exception to plan around rather than fear.

Sunshine hours matter more than rain here. Nine hours of daylight sun means sunscreen, a hat and a shaded lunch stop are the practical essentials, especially if you are travelling with children. The wind is the trap: it keeps you cool while the sun still burns, so reapply through the day rather than trusting how you feel.

The humidity figure explains why the heat can feel heavier than a dry 28°C at home. Book accommodation with air conditioning or good cross-ventilation, and treat the mid-afternoon as a rest period rather than a sightseeing slot.

Is the Sea Warm Enough to Swim in September?

Yes: the sea stays warm enough for swimming well into September, which is one of the month's clearest advantages over spring. Water lovers get long, comfortable sessions without the wetsuit that winter conditions demand. The island's breezier beaches, particularly around Costa Teguise, are also where wind sports take advantage of the same conditions.

Pick your beach by what you want from the water. Sheltered coves on the southern coast suit families and casual swimmers, while the eastern coast around Costa Teguise catches more wind and draws windsurfers and kitesurfers.

Crowds and Prices: Why September Feels Quieter

The clearest shift in September is who is on the island. With the school holidays over, the beaches are much quieter, flights and rooms are easier to find, and the atmosphere is calmer than in high summer. That makes September a strong candidate for a beach-based trip booked at short notice.

Lower demand usually means better value on accommodation and car hire than in July and August, when costs rise sharply. It does not mean the island empties: the main resorts and the big visitor sites still draw a steady flow, so book popular excursions ahead instead of counting on walking up on the day. If your dates are flexible, comparing September with October is worthwhile, since October brings autumn half-term crowds and a slight dip in temperature.

Nuestra Señora de los Dolores in Mancha Blanca

The island's patron saint is honoured at Mancha Blanca in the fiesta of Nuestra Señora de los Dolores, one of the most important dates on the Lanzarote calendar. It commemorates the tradition that prayers to the Virgin of Dolores halted a volcanic lava flow threatening the village, a feat said to have been repeated in 1824. Thousands of local people make the romería pilgrimage to the village carrying food and drink.

The fiesta is normally held on the Saturday closest to 15 September, so the date shifts each year within that window. Check the current year's date with the local ayuntamiento or the island's tourism office before building a trip around it, and expect the village to be very busy on the day itself.

Windsurfing and Kitesurfing Around Costa Teguise

The summer windy season runs through June to August, but Lanzarote keeps a steady breeze year-round, and the east coast around Costa Teguise sees more of it than anywhere else on the island. For windsurfers and kitesurfers, September offers warm water and air with fewer people competing for space on the water.

This same wind can make the east coast feel cooler and breezier than the sheltered south, which is welcome when you are active and less welcome if you planned to lie still. If you want tapas after a session, Costa Teguise has plenty of places to eat; our pick of the best tapas in lanzarote covers the styles to look for.

Hiking Timanfaya National Park and the Volcanoes Natural Park in the Heat

The volcanic landscapes are the reason many people come, but September heat demands respect. The park authorities limit where you can walk inside Timanfaya itself, with most of the terrain seen from the official visitor route, so check the rules before planning a hike. Start early, carry more water than you think you need, and take shade at midday.

August conditions make midday hiking uncomfortable, and September is only a step cooler, so treat any volcano walk as a morning activity. The Volcanoes Natural Park gives more freedom to walk than the protected core, but the black terrain radiates heat; good shoes and a hat matter more than a map.

Surfing as the Autumn Swell Arrives

September marks the start of the surfing season, with bigger waves arriving on the island's beaches as the school-holiday crowds leave. Surfers begin to appear through the month, and the conditions build towards stronger swells in November, when the waves get genuinely big.

If you are new to it, book a lesson with a local school rather than borrowing a board, and check the flags and currents at whichever beach you choose. The north and west coasts take the brunt of the swell; the sheltered south is better for swimming.

The La Graciosa Swim

September brings the annual 2.6km swim from Lanzarote to La Graciosa, a challenge that draws open-water swimmers to the strait between the two islands. It is a serious distance in open sea, so anyone entering should be a confident swimmer with the right support.

For non-swimmers, the reward is the island itself: a car-free, sandy place reached by ferry from Órzola, with quiet beaches and volcanic walks. Check ferry times and crossing details on the ferry company's site rather than relying on a timetable you found online.

September or October: Which Should You Pick?

September keeps more of the summer heat and has the quieter beaches of the two months, since the school holidays have just ended. October is a touch cooler, with temperatures around 27°C, and the sea remains warm for swimming, which makes it comfortable for hiking and cycling. If you want to weigh another stretch of the Costa Blanca with a similar late-summer feel, see our guide to Alicante in September.

The catch with October is the autumn school holiday, which brings higher prices and busier hotels for part of the month. If you want heat and empty sand, take September; if you want gentler walking weather and do not mind a busier week, October delivers.

What to Pack for Warm Days and Cooler Evenings

Pack for heat with a plan: shorts, T-shirts, swimwear, a hat, sunglasses and high-factor sunscreen, plus a light jacket or jumper for evenings, since nights are cooler than days even in September. Bring a refillable water bottle and use it constantly.

Add reef-safe sunscreen if you swim, and sturdy shoes if you plan to walk on volcanic ground, where the surface is rough and hot. A dry bag for boat trips to La Graciosa is worth the space.

How September Compares with Spring

Spring, from late February to April, is the other sweet spot on the island: warm weather without the summer crowds, though evenings stay cool enough for a jacket and the sea needs a wetsuit for most swimmers in winter and early spring. September gives you warmer water and reliably hot days in exchange for stronger sun.

For families tied to school terms, neither window may be open, in which case the summer months are the realistic option; our guide to lanzarote in july explains what peak heat and peak season actually feel like.

Where to Eat and What to Order

September evenings are made for eating outside, and Spanish timing applies: lunch runs from about 1:30 to 4pm, and dinner starts around 8:30 to 9pm. Arriving at 7pm will find many kitchens quiet, so adjust your day accordingly and use the late afternoon for a swim or a siesta.

Start with Canary Island staples: papas arrugadas with mojo, grilled fish, and goat's cheese. Our guide to lanzarote food explains the dishes worth ordering across the island, while the best restaurants in lanzarote picks out places worth planning an evening around.

Markets are a good daytime option when the heat is up: the Villa de Teguise Market is the island's best-known, and a morning there fits neatly with a shaded lunch. Our lanzarote markets guide covers what to expect.

Plan Your Visit

September gives you Lanzarote at its most comfortable: hot days, warm sea, quiet beaches and one of the island's biggest fiestas. Build your days around the sun, book the popular excursions ahead, and leave the evenings for long dinners outdoors.
