Spain UV Index by Month: At a Glance
Spain stretches from the cool Atlantic north to the subtropical Canary Islands, so UV varies enormously by region. Coastal mainland Spain peaks around UV 10 in midsummer, while Tenerife and Gran Canaria stay at UV 8–11 almost every month of the year.
This guide uses live and historical UV data from specialized UV monitoring services and public weather data sources, cross-referenced with WHO UV Index thresholds, to show you exactly when burn risk is highest and lowest in Spain.
Monthly UV Averages for Spain
The table below shows average peak UV index by month for Spain, the WHO risk category, and the typical burn time for Fitzpatrick skin type II (fair skin, light hair) with no protection at solar noon.
| Month | Avg Peak UV | Risk Level | Burn Time (Skin Type II) |
|---|---|---|---|
| January | 2 | Low | 34 min |
| February | 3 | Moderate | 22 min |
| March | 5 | Moderate | 13 min |
| April | 7 | High | 10 min |
| May | 9 | Very High | 7 min |
| June | 10 | Very High | 7 min |
| July | 10 | Very High | 7 min |
| August | 10 | Very High | 7 min |
| September | 8 | Very High | 8 min |
| October | 5 | Moderate | 13 min |
| November | 3 | Moderate | 22 min |
| December | 2 | Low | 34 min |

Best Months to Visit Spain for Sun Safety
The best months to visit Spain from a UV-safety standpoint are April to May and September to October. During this window, Spain in the shoulder months delivers warm beach weather with UV 5–8, perfect for the Costa Brava, Costa del Sol and the Balearics. UV bottoms out around 2 in January, which classifies as low risk under WHO guidelines.
For most travellers — particularly those with Fitzpatrick I, II or III skin types — these months allow for longer outdoor windows with conventional SPF 30 protection, fewer mid-afternoon retreats indoors, and a far lower risk of trip-ending sunburn. They also tend to coincide with shoulder-season pricing in Spain, making them a smart pick for budget-conscious travellers as well as sun-sensitive ones.
That said, shoulder months in the Mediterranean still produce UV 6–8 at midday, which means SPF 30 and a hat are still essential. Use the burn time calculator to see what your skin can actually handle on any given day.
Worst Months to Visit Spain for Sun Safety
The worst months to visit Spain for UV safety are June to August. These are the months when mainland Spain and the Canary Islands routinely peak at UV 10–11, with the Canaries seeing tropical-level UV almost year-round. UV peaks at 10 in June, which sits firmly in the very high risk band on the WHO scale.
For Fitzpatrick I and II skin types, unprotected burn times in June can drop to 7 min or less at solar noon. For darker skin types (IV–VI), the visible burn risk is lower, but DNA-level UV damage and long-term skin cancer risk remain significant — UV 11+ is genuinely dangerous regardless of skin tone.
If you must travel to Spain during these months, the safest pattern is to:
- Plan outdoor activities for the first three hours after sunrise, when UV is still climbing.
- Treat 10am to 4pm as a strict shade-or-indoors window unless wearing UPF clothing.
- Layer mineral SPF 30+ with a wide-brim hat and wraparound sunglasses.
- Reapply sunscreen every 90 minutes, not the standard two hours, in extreme UV environments.
- Check the live UV forecast every morning — afternoon clouds can hide UV 11 conditions.

Month-by-Month Breakdown for Spain
Below is a quick read of what to expect each month in Spain, ordered by season:
Peak UV: June (UV 10)
This is the most dangerous month for unprotected sun exposure in Spain. Treat every outdoor activity as a high-risk burn window and consider rescheduling beach days for early morning or late afternoon.
Lowest UV: January (UV 2)
This is the safest month to be outdoors in Spain. UV is officially low risk — most adults can be outside safely without sunscreen for short periods, though sunglasses are still recommended.
Shoulder months
The transition months — typically the period either side of June — give you most of the climate benefits of peak season with substantially lower UV. Look closely at the table above to find the sweet spot for your trip.
How Spain Compares to Other Destinations

Frequently Asked Questions
What is the UV index in Spain right now?
Live UV in Spain changes hour by hour and varies by exact location. Check the Spain live UV page for the current reading and a 16-day forecast.
When is Spain safest for fair skin?
Spain is safest for Fitzpatrick I–III skin types during April to May and September to October, when peak UV drops to 2–6. Even then, SPF 30, a hat and shade between 11am and 3pm are recommended.
What month has the highest UV index in Spain?
June typically records the highest UV in Spain, averaging UV 10 at solar noon. This corresponds to the WHO very high risk category.
Is Spain safe to visit during the worst UV months?
Yes — millions of people visit Spain during June–August every year. The risk is manageable with disciplined sun protection: avoid midday sun, wear UPF clothing, and reapply SPF 30+ every 90 minutes.
How does Spain's UV compare to home?
For most travellers from northern Europe, the UK or the northern US, Spain's peak UV (10) is two to three times higher than what you experience at home in summer. Burn times can be a fraction of what you're used to.
Sources and Methodology
UV averages in this guide are derived from:
- Specialized UV monitoring services — global real-time UV index data, used for current and forecast UV on Daily UV Tracker.
- Public weather data sources — historical hourly UV and weather data spanning multiple years per location.
- WHO UV Index reference — risk categorisation thresholds.
- US EPA UV Index Scale — burn time guidance by skin type.
Burn times shown for skin type II use the standard 67 minutes ÷ UV formula and assume no sunscreen, no clothing and clear-sky conditions at solar noon. Real-world burn times vary substantially with altitude, water reflection, ozone and individual skin response — always cross-reference the live Spain UV forecast and the burn time calculator before any extended outdoor activity.
Key Takeaways
- The best months to visit Spain for UV safety are April to May and September to October, when UV averages 2–6.
- The worst months are June to August, when UV climbs to 10 in June.
- Northern Hemisphere summer (Jun–Aug) is the peak UV window.
- Always check the live Spain UV index before planning outdoor activity, and adjust your protection accordingly.
- Combine the monthly averages above with the personalised burn time calculator for the most accurate planning.
