Tuesday 4 August sees temperatures at 31°C under completely clear skies, with a north-easterly blowing at around 35 km/h. Wednesday takes the edge off the temperature by a degree and puts the wind up to 40 km/h, the strongest reading of the week, then Thursday climbs back to 31°C with a bit of light cloud drifting through. Friday is the cleanest day on paper, clear skies and 31°C with the wind down to 30 km/h.
Overnight lows sit at 22°C to 23°C from Tuesday through to Monday, so there is no real cooling off after dark. Evenings stay shirt sleeve warm and mornings start mild.

UV 8 to 10 very high
Strong winds Tuesday to Thursday
The weekend brings a little more cloud without any real change in temperature. Saturday holds at 30°C with light cloud, Sunday sees longer cloudy spells at the same 30°C, and Monday closes the run at 29°C with a 10% chance of something falling first thing, which in an August forecast on Lanzarote usually amounts to nothing at all. AEMET has no weather warnings in place for the island.
High UV Levels
The UV index reads 10 from Tuesday through to Saturday, at the top of the very high band and one step short of extreme. Skin starts to burn in well under twenty minutes at that level, and the strong northerly makes it worse rather than better, because a constant breeze takes away the heat you would normally feel building on your shoulders. People who would have moved into the shade at midday stay put, and pay for it that evening.
Factor 30 or higher before you leave, another coat around lunchtime, and a hat for anything that involves walking. Get into that routine on day one and the burn never happens.
The Lanzarote Weather this week
Tuesday, Wednesday and Thursday are the windy days, running at 35 to 40 km/h from the north and north-east. That is a fresh breeze rather than a gale, but it is enough to move sand along the exposed beaches and enough to make an umbrella a losing battle. It also means the north and west coasts will be lively, with Famara getting a proper swell on it.
Friday onwards the wind drops to 25 to 30 km/h and the island settles. Friday is the standout day of the week, clear, hot and calmer, and the weekend follows on much the same with a bit more cloud in the mix. Monday is the coolest day at 29°C, which is still a warm August day by any measure.
Coast Versus Inland
The south coast is the place to be while the northerly is running. Playa Blanca, Puerto del Carmen and the Papagayo beaches all sit in the lee of the island and stay noticeably more sheltered than anything facing north. Costa Teguise will feel the breeze more, and Famara will be windy all week. The sea is at its August warmest now, so a midday swim is a pleasure rather than a shock.
Inland it is a different story. The Timanfaya National Park, La Geria and the villages around Tinajo and Yaiza get almost none of the coastal breeze, and the black volcanic ground holds heat all afternoon and gives it back. At 31°C the lava fields are hard going by late morning, so the volcanic walks want doing early or not at all.
Take Care in High Temperatures
Nothing this week is extreme by Canarian standards, but seven consecutive days above 29°C with warm nights adds up, particularly for anyone who has just arrived. Factor 30 minimum, topped up every couple of hours and every time you come out of the water. Wide hat, proper sunglasses, light and loose clothing.
Two to three litres of water a day for most adults, more if you are walking or cycling. Drinks by the pool are part of the holiday, but alcohol works against you in this heat, so keep water alongside. Children, older visitors and anyone with a heart or respiratory condition should stay out of the direct sun between 11am and 4pm, and it is worth keeping an eye on the group for headaches, dizziness or someone going quiet, which is usually the first sign.
Beaches, Boats and Early Starts
Anything on the water in the first half of the week is worth checking before you travel. A 35 to 40 km/h northerly makes for a rough crossing to La Graciosa from Órzola and can put smaller boat trips out of action altogether. If you have a catamaran cruise or a diving session booked for Tuesday, Wednesday or Thursday, ring the operator the day before. The south coast departures from Puerto Calero and Puerto del Carmen are less affected than anything going round the north.
From Friday the sea calms down and the whole week opens up for boat trips, snorkelling and diving. Walkers and cyclists should still be out early, before eight if possible, while the air is cool and the ground has not started throwing heat back.
AEMET updates the forecast daily, so if you have plans that depend on the wind it is worth a look the night before. Otherwise this is a straightforward hot and dry August week, with the sun cream and a sheltered beach the only real decisions to make.
