Peak Warmth Without Peak Crowds and the Sea at Its Warmest
September is the month that regular visitors to Lanzarote quietly rate as one of the best of the year. The peak-summer heat continues into the first half of the month, the sea remains at its warmest reading of the year, and by mid-September the school holiday crowds have gone and the resorts settle back into a more comfortable pace. Prices ease from the August peak, restaurants become easier to book, the beaches return to a more manageable level of occupancy, and the weather remains as good as anything the summer delivered.
If you can travel outside of the UK school schedule, September is arguably the best month of the year on Lanzarote. Warm weather, warm sea, minimal crowds, and a general sense that the island is exhaling after the intensity of the peak season.
The Numbers at a Glance
Average daytime temperature 28°C, average overnight low 21°C. Around eight hours of sunshine a day. Rainfall through the month averages around 5mm, still essentially dry but with the very first chance of the autumn Atlantic systems arriving late in the month. Sea temperature at 23°C, the warmest of the year.
What the Weather Actually Feels Like in Lanzarote in September
Daytime highs sit between 26 and 30°C on most days, warmer on the south coast at Playa Blanca and slightly cooler on the exposed north. The heat has usually softened from the August peaks, and the extreme events that can push temperatures into the mid 30s become less frequent through September. Evenings stay warm at 21 or 22°C, comfortable for outdoor dinner without any layer needed. Overnight lows are still balmy.
UV levels remain in the very high category through September, typically at 9 or 10 on most days. Sun protection is still essential rather than optional, particularly for anyone spending long hours at the pool or beach. Sea temperatures at 23°C are the warmest of the year, and swimming is at its most inviting. The gap between air and water temperature is smaller than at any other point in the calendar.
What to Pack if you’re Visiting Lanzarote in September
Full summer wardrobe throughout the first half of the month. T-shirts, shorts, light dresses, swimwear. Sun protection remains a priority: factor 30 or higher sunscreen, wide-brimmed hat, UV-blocking sunglasses, and a water bottle. A very light layer for the cooler evenings later in the month, though most people won’t need one before October.
Walking shoes for excursions into the volcanic interior, which becomes more comfortable through September as the peak heat starts to ease. Something smart-casual for restaurants and evenings in the resort areas. Beach kit for the pool and coast.
Sea Temperature at Its Best
The single strongest argument for September is the sea. Water temperatures peak around 23°C through the month, which is the warmest reading Lanzarote records all year. For anyone who found August’s beach days good but who would have appreciated slightly cooler air temperatures and slightly warmer sea, September delivers exactly that. Snorkelling, diving, swimming and stand-up paddle boarding all reach their peak conditions.
Diving in particular is at its best. Visibility across the popular sites at Playa Chica and Playa Blanca is often excellent, marine life is active, and the water is warm enough for comfortable dive times without a heavy wetsuit. The angel shark breeding season begins in October, so sightings pick up towards the end of September as the population moves into the shallower waters.
Crowd Levels Drop from Mid-Month
UK schools typically return to term in the first week of September, and the effect on Lanzarote’s visitor numbers is immediate. The first week of the month still carries some of the August intensity, but from around the 8th or 10th onwards the resort areas noticeably empty out. By mid-month the beaches feel spacious, restaurants are comfortable to walk into, and the attractions run without the peak-season pressure that defined July and August.
This is the shoulder season pattern that regular visitors know and value. Same weather, half the people. The couples and older visitors who make up most of the September traffic tend to be quieter and more restaurant-focused than the family crowds of August, and the whole island runs at a more measured pace as a result.
Lanzarote Beaches Without the Pressure
Papagayo returns to something like its natural state through September, with arrivals possible at more civilised hours and comfortable spots easier to find. Playa Grande in Puerto del Carmen, Playa Mujeres near Playa Blanca, Las Cucharas in Costa Teguise and the smaller coves at Playa Quemada and El Golfo all become more usable than they were through August. Famara remains the surf and windsurf destination, though the trade winds start to soften through September and traditional sunbathing days become more viable.
Where to Walk and Cycle in Lanzarote in September
Walking becomes more comfortable through September as the heat starts to ease. Early morning starts are still sensible for anything in the volcanic interior, but the middle of the day is less punishing than in August. Caldera Blanca, the Famara cliffs and the Los Ajaches range all reward September walkers. The Camino de la Colmena and the trails around Haría in the north are worth exploring as the volcanic hills start to show the first hints of green after any early autumn rain.
Cycling picks up significantly through September as European amateur and professional cyclists start returning for the autumn training season. The roads through La Geria and along the coastal routes see more Lycra than they did through July and August, though the volume remains well below the pre-IRONMAN peak in April and May.
Wine Harvest in La Geria
The grape harvest in La Geria typically runs from late July into September depending on the varietal and the vintage. Malvasía Volcánica and the other white grapes are usually in first, with the reds following through August and into September. Visiting the wineries during or immediately after the harvest is one of the more rewarding wine tourism experiences on offer, with the bodegas working at their most active and the winemakers happy to talk through the year’s grapes for anyone showing interest.
Lanzarote Attraction Numbers Ease Off
Timanfaya, Jameos del Agua and the other major CACT sites all become easier to book from mid-September onwards. Same-day availability at Timanfaya returns as a realistic option, and the popular morning slots are less contested. The Teguise Sunday market runs at a more comfortable pace than in August, with the summer season stalls still in place but the crowd levels back at manageable levels.
Eating and Drinking in Lanzarote in September
Restaurant reservations become genuinely easier through September. The better places in Puerto del Carmen, Playa Blanca and along the Marina Rubicón still benefit from advance booking for Friday and Saturday evenings, but weekday tables become straightforward to secure and walk-ins are viable at many of the good places. The wine country restaurants along the La Geria route are at their most welcoming, often combined with harvest tastings for anyone interested in the wine story.
September is a good month for trying the places you couldn’t get into during August. The waiting lists have eased, the pace has slowed, and the restaurants themselves seem to relax after two months of running at full capacity.
The First Sign of Autumn Weather
By the last week of September, the very first Atlantic systems can occasionally reach the Canaries. Rainfall for September averages around 5mm, still essentially dry, but the possibility of a genuinely rainy day exists for the first time since April. These events remain rare and short-lived, but they mark the start of the transition into autumn. AEMET forecasts start to show more variety through the last week of the month as the summer trade wind pattern begins to break down.
A Word on the Wind
The trade winds soften through September, particularly through the second half of the month. Wind speeds still average 20 to 30 km/h on most days but the frequency of stronger events drops noticeably. Famara becomes less consistently windy and traditional beach days become more viable there than they were in July or August. The south coast resorts feel calmer as the summer pattern eases.
Peak summer weather without peak summer crowds. Warmest sea of the year. Easier restaurants, easier attractions, easier beaches. Wine harvest in La Geria. Weather comfortable enough for walking to become properly rewarding again. Prices that drop back from the August highs. For regular Lanzarote visitors who can travel outside the school schedule, September is arguably the strongest month on the calendar and consistently the answer when locals are asked which month they would choose themselves.
