Lanzarote Weather Forecast 15th July - 21st July 2026

A Settled Week Ahead

The forecast for Arrecife opens Wednesday 15 July at 29°C under completely clear skies, before ticking up to the weekly peak of 30°C on Thursday. From Friday onwards the daily maximum settles at 29°C every day except Monday, which cools very slightly to 28°C. Overnight minimums hold consistently between 21°C and 22°C throughout the period, meaning the warm air lingers into the night and dawn temperatures never drop far below the low 20s.

The skies stay almost entirely clear through Thursday, before the cloud starts to build in the afternoons from Friday onwards. Not enough to worry about, and no rain forecast on any day of the seven. What does change from Friday is the wind, with the northerly trades stepping up from the moderate 30 km/h you get most of this week to gusts hitting around 40 km/h through Saturday, before dropping back to something calmer by Monday.

The Sun is Stronger Than the Heat Suggests

The temperatures this week aren't extreme by Lanzarote standards. High 20s, warm nights, breezy afternoons. What is extreme is the UV, sitting at 10 every single day for the whole week. That's the sneaky one. You feel comfortable in the breeze, you don't feel like the sun is hammering you, and then you look in the mirror on day three and wonder what happened to your shoulders.

Anyone who's spent a summer here knows the drill. Sunscreen on before you leave the room in the morning, top-up at lunch, hat on when you're walking anywhere. The people who catch the sun worst tend to be the ones who thought they'd be fine because it didn't feel that hot. Take it seriously from Wednesday onwards and you'll be fine all week. Skip a day and you'll pay for it.

What to Expect Each Day

Wednesday and Thursday are the pick of the week if you want the classic Lanzarote picture-postcard days. Blue sky, no cloud, 29 to 30°C, moderate breeze. Thursday nudges up to the weekly high of 30°C, which will feel proper warm inland but still comfortable on the coast.

Friday is where the wind starts talking. Temperature holds at 29°C, sun stays out, but the northerly kicks up to around 35 km/h and you'll notice it, especially on the seafront in the afternoon. Saturday and Sunday are the windy days. Same temperature, same sunshine, but gusts pushing 40 km/h particularly along the north-facing coasts. The south coast resorts stay much more sheltered.

Monday it all calms down again, temperature dips a touch to 28°C, wind settles back to a comfortable 20 to 25 km/h. Tuesday finishes the week at 29°C with light cloud and a gentle breeze. If you're picking a day for a long walk or a bike ride, Wednesday, Thursday or Monday are your best bets.

Windsurfers Head North This Weekend

The stronger northerly wind from Friday through Sunday hits different parts of the island completely differently. If you're staying in Puerto del Carmen, Playa Blanca or Costa Teguise, the south-facing coasts do their job of sheltering you from the worst of it. You'll notice the breeze, particularly along the Avenida in Puerto del Carmen, but the beaches will still be comfortable and the pools will still be pool weather.

Famara is a different story. Anyone who's ever tried to sunbathe up there on a windy weekend knows what's coming. Sand in the picnic, parasols acting like sails, and the kind of gust that makes you glad you double-tied your beach bag. On the flip side, the surf and kitesurf schools up in Caleta de Famara will be having their best weekend in weeks. If you've got a lesson booked, or you fancy watching some proper riders showing off, this is the weekend to head north.

How the Different Parts of the Island Compare

The south coast resorts track pretty closely with the Arrecife forecast, and the Atlantic breeze along the seafronts of Puerto del Carmen, Playa Blanca and Costa Teguise keeps things comfortable even on the warmest afternoons. Sea temperatures are into the low 20s now, which means the water is properly refreshing rather than the shock it can be earlier in the year. A midday dip is one of the better ways to break up a long day of sunshine.

The interior is a different climate again. Timanfaya, La Geria and the villages up around Tinajo and Yaiza sit away from the coastal breeze, and the black volcanic ground holds and radiates heat through the day. Somewhere like Caldera Blanca at midday in July is genuinely hot, and the walks and hikes across the volcanic landscape are best done first thing in the morning when the light is soft and the ground hasn't warmed up yet.

Sunscreen, Water and Shade Between Eleven and Four

The rules for a week like this are the ones you already know but which are worth remembering. Factor 30 or higher, applied properly and topped up every couple of hours. More often if you're in and out of the pool or the sea. Wide-brimmed hat, sunglasses that actually block UV, light clothes. Between about 11am and 4pm the sun is at its worst, and finding an hour or two in the shade during that window is the difference between a good week and a burnt week.

Water goes down easier than you think. Two to three litres a day for most adults, more if you're active. Alcohol is fine, but it dehydrates you faster than water rehydrates you, so pace yourself if you're on the beers by the pool from lunchtime. Older visitors, kids, and anyone with a chronic health condition should take a bit more care with the middle-of-the-day window. Heat exhaustion sneaks up on people, and the signs (headache, dizziness, nausea, unusually quiet) are worth watching for in the family group.

Beach Days, Boat Trips and Walking in the Cool Hours

This week is close to ideal for everything most people come to Lanzarote for. Beach days, pool time, snorkelling, diving, catamaran trips, sunset dinners on the marina. All of it works in these conditions. The stronger wind on Saturday and Sunday might affect some of the smaller boat trips and the La Graciosa ferry could see rougher crossings than usual, so if you've got a boat booking over the weekend it's worth a quick check with the operator on Friday afternoon.

For the more active side of the holiday, the volcanic walks and cycling routes are best tackled early. Head out at 7 or 8 in the morning and you get the good light, the cool air and the empty trails. By midday the ground is radiating heat and the same walk becomes a slog. Cyclists know this already. If you spot a group of Lycra-clad riders climbing the road up to Mirador del Río at half seven in the morning, that's why.

The Kind of Week People Book Lanzarote For

After the drama of the May heatwave and the wind alerts that caused the Sonidos Líquidos cancellation in early June, this week is the reason people book Lanzarote in the first place. Warm, sunny, dry, breezy in the right places, sea warm enough to swim, sky the right shade of blue. Not much more to say about it.

AEMET updates the forecast throughout the week, so if you're planning something that depends on the weather, particularly anything on the water over the weekend, it's worth checking closer to the day. Otherwise, get the factor 30 out, find your favourite beach, and enjoy the sort of week that keeps people coming back year after year.
