IRONMAN Weekend, the First Real Warmth and Sea Temperatures Climbing
May is when Lanzarote genuinely moves into its summer character. Daytime temperatures climb into the mid 20s, rainfall is essentially zero, and the sea starts warming towards genuinely swimmable temperatures. Two big events shape the month: the IRONMAN Lanzarote takes over the island in late May, and Día de Canarias on 30 May brings the island’s biggest cultural celebration of the calendar. Between them they give May a distinct character that separates it from the quieter shoulder months either side.
Rainfall drops to almost nothing through May, sunshine hours push up to nine a day, and the island moves into a properly settled pattern that will hold through to October. If you want warm weather without the peak-summer intensity, and if either the IRONMAN or Día de Canarias appeals as a reason to build a trip around, May is a strong choice.
The Numbers at a Glance
Average daytime temperature 24°C, average overnight low 17°C. Around nine hours of sunshine a day. Average rainfall through the month is just 2mm, with rain most likely at the very start of the month if at all. Sea temperature climbing from 18°C at the start of May to 19°C by the end.
What the Weather Actually Feels Like in Lanzarote in May
Daytime highs sit between 22 and 26°C on most days, warmer on the south coast and warmer still inland away from the sea breeze. The 2026 May saw a significant heatwave that pushed inland temperatures above 34°C during the last week of the month, which is unusual but not unheard of when hot air pushes north from the African continent. Standard May conditions are less extreme but the possibility of a warm spell is worth being aware of.
Evenings drop to around 17 or 18°C, comfortable for outdoor dining without needing more than a light layer. UV levels are strong through May, particularly during the middle of the day, and sunburn is a real risk for anyone not applying proper sun protection. Sea temperatures climb steadily through the month, reaching about 19°C by the end. Comfortable for a proper swim if you’re used to Atlantic water, still cool for anyone coming from Mediterranean beaches.
What to Pack when you Visit Lanzarote in May
Summer wardrobe with a light layer for the evenings. T-shirts, shorts and light trousers for the daytime. A fleece or hoodie for the cooler evenings and any early morning excursions. Swimwear is properly useful for both beach and pool time. Walking shoes if you’re planning to head out into the volcanic interior, and something smart-casual for restaurants and evenings in the resort areas.
Sun protection needs to be treated seriously in May. Factor 30 or higher sunscreen applied properly and reapplied through the day. A wide-brimmed hat, quality UV-blocking sunglasses, and a bottle of water for any time spent walking away from the coast. The Lanzarote sun in May is stronger than most first-time visitors expect.
IRONMAN Lanzarote and Race Week
IRONMAN Lanzarote traditionally takes place on the fourth Saturday of May and dominates the island for the week leading up to race day. More than 1,400 athletes from around the world descend on Puerto del Carmen, road closures affect every municipality on race day itself, and the atmosphere across the resort areas takes on a distinctive endurance-sport character. The 2026 race was confirmed as the last edition organised by Club La Santa, and the event is expected to continue under new management from 2027 onwards.
Even if you’re not a triathlon fan, IRONMAN weekend is worth experiencing. The 7am swim start at Playa Grande under sunrise is one of the more memorable images available on the island. The finish line atmosphere in Puerto del Carmen from evening onwards, with athletes crossing after 10 to 16 hours of racing, is genuinely emotional. Road closures make travel logistics on race day itself complicated, particularly for anyone with airport transfers or restaurant bookings, so plan around them.
Día de Canarias on 30 May
The Canary Islands’ most important cultural celebration falls on 30 May and marks the anniversary of the first session of the Canary Islands Parliament in 1983. The celebrations run across the weekend nearest to the date and span every municipality on Lanzarote. Arrecife, Puerto del Carmen, Yaiza, Tinajo, Costa Teguise, Haría and San Bartolomé all run their own programmes of traditional music, folklore, gastronomy, sport and family activities.
For visitors, Día de Canarias offers one of the best opportunities of the year to see Lanzarote as it sees itself. Traditional dress, lucha canaria wrestling demonstrations, timple music, folklore performances, and the food that defines the island’s cultural identity all come to the surface across the weekend. The Yaiza Cheese and Goat Fair and Tinajo’s Degustando tapas fair are among the highlights across the smaller municipalities.
Lanzarote Beaches at Their Best
May is the month when the beaches genuinely feel like beach beaches again. The Papagayo coves near Playa Blanca deliver clear water and golden sand at their most inviting. Playa Grande in Puerto del Carmen fills through the day but rarely feels overcrowded until the school holiday months arrive. Playa Mujeres offers a calmer alternative with easier access than Papagayo. The Playa de las Cucharas in Costa Teguise sees the return of the windsurfing school season.
Famara in the north-west remains the windier option, better suited to surfers and kitesurfers than to traditional sunbathing days. The trade winds are firmly established by May and the exposed north coast beaches see the full brunt of them. For water sports this is exactly the point.
Walking & Hiking in Lanzarote in May
The walking is still excellent through May but starting earlier becomes more important as the month progresses. Caldera Blanca, the Famara cliffs and the Los Ajaches range are all rewarding, but doing them in the morning rather than the middle of the day makes a significant difference to the experience. By the end of May, midday walks in the volcanic interior become genuinely hot and much less comfortable than the early morning equivalent.
Cycling continues at strength through May, particularly during the run-up to IRONMAN when the roads are noticeably busier with training groups. After race weekend the volume drops significantly and the roads return to their normal rhythm.
Lanzarote Attractions and Booking in May
Timanfaya, Jameos del Agua and the other major CACT sites are working at higher demand levels through May. The Timanfaya timed-entry booking system is essential rather than optional through the month, with the best morning slots going early. IRONMAN weekend produces particular pressure on all the major attractions, and Día de Canarias weekend sees local family visits alongside the international tourist demand.
Eating and Drinking in Lanzarote in May
Book ahead. May is busy enough at the popular restaurants that walk-ins become difficult, particularly at the weekend and during IRONMAN and Día de Canarias weekends. The seafood restaurants in Puerto del Carmen, Playa Blanca and along the Marina Rubicón all see strong demand. The wine restaurants along the La Geria route remain slightly easier to book than the coastal options.
The Yaiza Cheese and Goat Fair typically falls at the end of May as part of the Día de Canarias celebrations and offers one of the more distinctive food events of the year. The wine tourism is at its most visually rewarding, with the vines showing full spring growth and the black volcanic soil looking dramatic against the greenery.
A Word on the Wind
The trade winds are properly established through May, running consistently from the north and north-east at 20 to 30 km/h on most days and stronger on the exposed coasts. This is welcome cooling breeze on the south coast beaches and the driving force behind the north coast water sports scene. Famara, Órzola and the exposed northern coastline can see wind gusts pushing 40 to 50 km/h on the windier days, particularly during the second half of the month.
Warm enough for the beach, dry enough that rain is essentially not a factor, quiet enough at either end of the month that the island still feels manageable, and with two of the year’s biggest cultural events sitting in the middle. If you build a trip around either the IRONMAN weekend or Día de Canarias, May delivers content that no other month on the calendar offers. If you want the warm weather without either event, the first two weeks of the month are the quieter option.
