UV Index in Europe: Country-by-Country Breakdown

Europe's UV Landscape

Europe stretches from the Arctic Circle to the southern Mediterranean, producing a UV gradient that spans the full WHO scale. Northern destinations (Iceland, Norway, Finland) rarely exceed UV 5 even at midsummer; Mediterranean countries (Greece, southern Italy, Spain) routinely hit UV 9–10 in July and August. Understanding this gradient is essential for anyone planning a European trip.

For the full regional breakdown and live data, see our Europe destinations directory.

Northern Europe

Iceland

Peak summer UV: 4–5. Year-round low UV. Reykjavík is among the easiest UV environments in Europe. Long daylight hours but consistently moderate intensity.

Norway

Peak summer UV: 5–6 in the south (Oslo, Bergen), 3–4 in the Arctic (Tromsø, Lofoten). Winter UV essentially zero.

Sweden

Peak summer UV: 5–6 in Stockholm and the south, 3–4 in Lapland. Long winter darkness, mild summer UV.

Finland

Peak summer UV: 5. Forest-and-lake summer destinations with extremely long daylight but moderate UV.

Denmark

Peak summer UV: 5–6. Coastal cycling and Copenhagen city breaks at moderate UV.

The British Isles

United Kingdom

Peak summer UV: 5–7 in southern England, 4–5 in Scotland. London rarely exceeds UV 7 even in July; Edinburgh rarely exceeds UV 6. The UK Met Office UV Index publishes daily forecasts.

Ireland

Peak summer UV: 5–6. Persistent Atlantic cloud filters even peak summer. Comfortable for outdoor exploration with basic protection.

Western Europe

France

UV varies sharply by region:

Paris and northern France: UV 6–7 in summer.
Brittany and Normandy coast: UV 6–7.
Lyon and central France: UV 7–8.
Côte d'Azur and Provence: UV 8–10 in July–August.
Corsica: UV 9–10.

Belgium and the Netherlands

Peak summer UV: 5–6. Reliably moderate, ideal for cycling tours and city breaks.

Germany

UV varies by region:

North Sea coast and Hamburg: UV 5–6.
Berlin: UV 6.
Munich: UV 7.
Bavarian Alps: UV 7–9 (altitude effect).

Switzerland and Austria

Peak summer UV: 8–10 at altitude. Mountain destinations (Zermatt, Innsbruck, the Tyrol) are deceptively dangerous due to altitude amplification and snow reflection in winter. The WHO emphasises altitude as a major UV multiplier.

Southern Europe

Spain

Peak summer UV: 9–10 in central and southern Spain.

Madrid and central plateau: UV 9–10 in July–August.
Barcelona and Catalan coast: UV 9–10.
Andalucía (Seville, Málaga, Granada): UV 10.
Canary Islands: UV 9–11 year-round (subtropical).
Northern Spain (Bilbao, Santiago): UV 7–8.

Portugal

Peak summer UV: 9–10. Lisbon hits UV 10 in July; the Algarve sees UV 10–11 with beach reflection adding to direct exposure. Madeira measures UV 9–11 year-round.

Italy

UV varies sharply north to south:

Milan and northern Italy: UV 7–8.
Florence and Tuscany: UV 8–9.
Rome: UV 9–10.
Naples and Amalfi Coast: UV 9–10.
Sicily: UV 10–11.
Sardinia: UV 9–10.

Greece

Peak summer UV: 10–11. Athens, Santorini, Crete and Mykonos all measure UV 10+ in July–August. Beach reflection and full-day outdoor culture combine to produce significant burn risk.

Cyprus and Malta

Peak summer UV: 10–11. Among the highest UV in Europe, with extended sun-and-sea tourism.

Croatia, Montenegro, Albania

Peak summer UV: 9–10 along the Adriatic coast. Dubrovnik, Split, Kotor and Dhërmi all measure UV 9–10 in summer.

Eastern Europe

Poland, Czech Republic, Slovakia

Peak summer UV: 7–8. Moderate continental climate UV.

Hungary, Austria, Slovenia

Peak summer UV: 7–9. Budapest at UV 8 in summer; Slovenia's Adriatic coast at UV 9.

Romania, Bulgaria

Peak summer UV: 8–9. Black Sea coast (Constanța, Varna) at UV 9–10.

Russia (European)

Peak summer UV: 5–6 in St. Petersburg, 6 in Moscow, 7 in Sochi.

Ukraine

Peak summer UV: 7–8 in Kyiv, 8–9 on the Black Sea coast.

The Baltic States

Estonia, Latvia, Lithuania

Peak summer UV: 5–6. Underrated moderate-UV summer destinations.

How European UV Compares to the Rest of the World

European UV peaks (10–11 in the Mediterranean, 4–5 in the Nordic countries) sit well below the global maximum (UV 13–14 at high-altitude tropics like La Paz or Quito). For sun-sensitive travellers, even Mediterranean peak UV is more manageable than tropical destinations like Bali or Cancún.

For comparison, see our cities with highest UV guide.

Seasonal Planning for European Travel

A practical pattern:

Summer (June–August): Mediterranean UV at peak; head north for moderate UV.
Spring (April–May): Mediterranean shoulder season at UV 6–8; ideal for sun-sensitive travel.
Autumn (September–October): Mediterranean shoulder season at UV 5–7; very comfortable.
Winter (December–February): Most of Europe at UV 1–3; minimal protection needed.

Protection Strategy by Region

Northern Europe (UV 4–6): SPF 30, hat, sunglasses for extended outdoor time.
Western Europe (UV 6–8): SPF 30+, hat, UV400 sunglasses, plan around midday.
Mediterranean (UV 9–11): SPF 50, UPF 50+ shirts, broad-brim hat, schedule around midday.
Mountain destinations (UV 8–10 + altitude): Treat as UV 11+; full kit, frequent reapplication.

Key Takeaways

Europe spans the full UV spectrum, from Icelandic moderation (UV 4–5) to Greek extremes (UV 10–11). Match your destination and season to your personal UV comfort range, use a daily tracker like Daily UV Tracker for live readings, and pack protection appropriate for the regional norm. Done well, Europe offers some of the world's most flexible UV travel options — letting you choose anything from gentle Nordic light to intense Mediterranean sun, with full information at every step.

For deeper context on the topics covered above, the following resources expand on the data, science and practical guidance referenced throughout this article. Daily UV Tracker pulls forecast data from established meteorological providers and aligns its risk thresholds with the international standards defined by the World Health Organization, the United States Environmental Protection Agency and the National Oceanic and Atmospheric Administration. Reading the source material directly is the best way to build a working understanding of how ultraviolet radiation behaves, how skin reacts to sustained exposure, and why a daily UV check is one of the highest-leverage habits for long-term skin health.

How to apply this in practice

The single most effective change most readers can make is to fold a UV check into the same morning routine as the weather forecast. Open Daily UV Tracker, note the day's peak UV value and the time it occurs, and choose an outdoor window that sits comfortably outside that peak. On days flagged as very high or extreme, treat shade, broad-spectrum SPF 30+, UPF clothing and wraparound sunglasses as non-negotiable rather than optional. When travelling, repeat the exercise the night before arrival so you are not caught out by an unfamiliar UV climate. Combined with the sources listed above, this habit converts an invisible risk into a set of small, repeatable decisions that compound into meaningful long-term skin protection.
