Peak midday UV by month in Kigali

It's October: on clear days, the midday sun here usually peaks around UV 13–15. That's very intense: around midday you need shade, covering clothes and sunscreen.

The sun is strong here all year round: even in the mildest months, midday UV reaches about 12, so protection is needed in every season. Treat these numbers as the most sun you should expect around noon: clouds typically lower the real value, while reflections from snow, sand or water can add to the UV your skin actually receives. Today's actual UV is in the forecast above.

In October the strong sun is in the southern hemisphere: UV reaches high levels across most of it, while the northern hemisphere outside the tropics has its mild season.

UV in Kigali: today, tomorrow and through the year

In Kigali it's currently UV 8 (very high), and with the day peaking at 11 (extreme), protection is worth keeping on until 16:00. Patchy cloud is holding the peak down a little, against UV 13 under clear skies. Up at 1,552 m, the thinner air at this altitude lets through more UV than at sea level.UV backs down tomorrow, peaking near UV 9 (very high) around 11:00, but the hours from 08:00 to 16:00 still call for protection.There is no quiet season in Kigali. The gentlest months still reach about UV 12 on their strongest days, the strongest months about UV 17, and October falls between them.

UV index map for Kigali and nearby cities

This map shows the current UV forecast for Kigali and the area around it. One forecast value covers a region of roughly 40 km, so it is a good guide for the area as a whole rather than an exact reading for one spot. In places with big height differences, or where the ground is covered by snow, the real UV can differ from what the map shows.

About the UV Index

What is the UV index?

The UV index (UVI) is an international standard measure of the strength of ultraviolet radiation from the sun at a particular place and time. It ranges from 0 (nighttime) to 11+ (extreme). Higher values mean greater risk of sunburn, skin damage, and eye injury. The UV index was developed by the World Health Organization (WHO) to help people protect themselves from harmful UV radiation.

How do I check the UV index today?

This page shows the live UV index for your location using data from the Copernicus Atmosphere Monitoring Service (CAMS). You get the current UV level, an hourly UV forecast chart for today and tomorrow, and the exact peak UV time — so you always know when sun protection is most important.

When is UV radiation strongest?

UV radiation is typically strongest between 10:00 and 16:00, when the sun is highest in the sky. However, the exact peak time and intensity depend on your latitude, the season, altitude, cloud cover, and ozone levels. Check the UV forecast chart above to see today's exact peak time for your location.

How can I protect myself from UV radiation?

Apply broad-spectrum sunscreen, wear protective clothing and a wide-brimmed hat, seek shade during peak UV hours, and wear UV-blocking sunglasses. The WHO recommends sun protection when the UV index is 3 or above.

Where does the UV data come from?

The hourly UV index on this site comes from the Copernicus Atmosphere Monitoring Service (CAMS), operated by ECMWF on behalf of the European Union. CAMS calculates the UV biologically effective dose using total column ozone, aerosol optical depth, and cloud cover. The global forecast has a spatial resolution of approximately 40 km and provides hourly UV index values for up to 5 days ahead.

What does "clear-sky UV index" mean?

The clear-sky UV index shows how strong ultraviolet radiation would be if there were no clouds at all. It is calculated using the same atmospheric data — ozone column thickness, aerosol concentrations, and solar angle — but assumes completely cloudless conditions. Comparing the actual UV index with the clear-sky value shows how much clouds are reducing UV exposure at any given time. On overcast days, actual UV can be significantly lower than the clear-sky value.

How often is the UV forecast updated?

The CAMS global UV forecast is updated twice daily, based on model runs initialized at 00:00 and 12:00 UTC. Weather data such as temperature, cloud cover, and sunrise/sunset times is updated every 1–6 hours depending on the region, using weather models from national meteorological services via Open-Meteo. The first 1–2 days of the forecast are typically the most accurate.

What does the WHO recommend for each UV level?

Low (0–2) — No protection needed. You can safely enjoy being outside
Moderate (3–5) — Seek shade during midday hours. Wear a shirt, apply broad-spectrum sunscreen, and put on a hat. Wear UV-blocking sunglasses
High (6–7) — Seek shade during midday hours. Wear a shirt, apply broad-spectrum sunscreen, and put on a hat. Wear UV-blocking sunglasses
Very High (8–10) — Avoid being outside during midday hours. Make sure you seek shade. Shirt, broad-spectrum sunscreen and hat are a must
Extreme (11+) — Avoid being outside during midday hours. Make sure you seek shade. Shirt, broad-spectrum sunscreen and hat are a must
