Frequently asked questions

How high is the UV index in Lanzarote in summer?

At the summer peak the UV index typically reaches 11 (Jul) — very high to extreme. Unprotected fair skin burns in roughly 14 minutes.

Do I need sunscreen in Lanzarote in winter?

Yes. A typical December midday reads UV 4 — early-summer level for the UK. SPF 30–50 for the face is sensible.

Is the sun stronger in Lanzarote than at home?

Considerably. A UK or US-northeast summer rarely passes UV 8; in Lanzarote, 11 is normal — and the high-UV season lasts longer. Sea breeze and wind hide the exposure.
