Recommendations for this city

Canary Islands, very high UV year-round (subtropical latitude). Even January gives UV 4-5. Apply extra caution on beaches and in the mountains due to additional UV reflection.

UV guide for Las Palmas

Las Palmas sits at 28.12 N, -15.43. Its UV index follows a seasonal cycle driven by latitude and mean cloud cover. This page offers real-time data from Open-Meteo and a customisable calculator so you know how long you can stay in the sun without burning.

Canary Islands, very high UV year-round (subtropical latitude). Even January gives UV 4-5.

Sunburn occurs when the accumulated UVB dose exceeds your MED (Minimal Erythemal Dose), which depends on your Fitzpatrick skin type. Fair skin (I-II) has very low MED: in Las Palmas in summer, type II skin can burn in less than 15 minutes unprotected at solar noon.

Specific recommendations: wear a hat, seek shade during the middle hours, apply SPF 30-50 every 2 hours and check this index before planning outdoor activities. Children, elderly and people with very fair skin or photosensitising medication should be extra careful.

UVA radiation passes through clouds and glass: watch out on overcast days and in cars with closed windows. UV 400 sunglasses are essential to prevent early cataracts and macular degeneration.

UV in Las Palmas de Gran Canaria: latitude, altitude and cloud

Why the sun in Las Palmas de Gran Canaria hits the way it does

The UV index does not depend on heat but on how high the sun stands above the horizon, and that is pure geometry. Las Palmas de Gran Canaria sits at 28.10° of latitude, so at solar noon the sun reaches 85° of elevation in June — its highest point of the year — and drops to 39° in December. The more vertical the ray, the less atmosphere it crosses and the less ultraviolet is filtered out on the way: between those two extremes the midday UV changes by a factor of several times.

Altitude adds to that. The reference observatory stands at 269 metres, and UV rises by roughly 10 % per thousand metres because there is less air above: some 3 % more than at sea level under the same sun. The 269 metres of the Tafira observatory already add around 3 % of UV over sea level, and climbing to the summit multiplies the correction: at Los Pechos, at 1,900 metres, it is almost 20 % more than on Las Canteras beach.

Cloud protects less than it seems

In Las Palmas de Gran Canaria, June averages 1.8 clear days and only 8.5 overcast ones, per AEMET’s 1991-2020 normals at Las Palmas De G.C. (Tafira Cmt). But that is not the important figure: a thin or broken cloud layer filters far less ultraviolet than visible light, so a whitish sky cuts the feeling of sun without cutting much UV, and in some cases scattered cloud increases it by reflecting radiation into the gaps. The sunburns that catch people out are almost always from cloudy days.

How to read this alongside the index above

The figures in this table are geometry and climatology: they say how much sun there can be and how high it climbs, not how much UV there will be today. The calculator’s index does come from today’s forecast, which also accounts for actual ozone and cloud. Read them together: the table explains why the UV in Las Palmas de Gran Canaria is what it is, and the calculator says what today calls for.

One last thing that does not change with the city: 70 % of the daily ultraviolet dose arrives in the four hours around solar noon, which in Spanish summer time is roughly 13:30 to 17:30. Avoiding that window does more than any cream.
