Serbia Issues Red Meteo Alert Over High UV Radiation
Red alert for June 20 and 21: UV index of 7 to 8 across most of the country, up to 9 on Kopaonik. Here is how to stay safe and how hot the weekend will get.

- Serbia's RHMZ issued a red meteo alert for June 20 and 21 over very high UV radiation.
- The UV index is 7 to 8 across most of the country, reaching 9 on Kopaonik, a critical level.
- Weekend temperatures run from 30 to 35 degrees Celsius, locally up to 36 on Sunday.
- Doctors advise avoiding the sun between 10 a.m. and 5 p.m.
Is it really dangerous to go outside this weekend? Yes, but only at the wrong time and without protection. Serbia’s Republic Hydrometeorological Service (RHMZ) has issued a red meteo alert for June 20 and 21 over very high ultraviolet radiation, the top level of warning in this category.
A red alert does not mean you should stay locked indoors all day. It means unprotected skin gets damaged faster than you think, sometimes after only a short time in the sun. So it helps to know the exact numbers and clear steps before you head to the market, the garden, or a day trip.
How high is the UV index, and where is it most dangerous?
The UV index shows how strong the sun’s radiation is at a given moment. Values from 8 to 10 count as very high, and anything above 6 calls for serious protection. According to RHMZ data, the UV index across most of Serbia sits between 7 and 8 this weekend.
The red alert is in effect for a string of cities. Among them are Vrsac, Loznica, Valjevo, Svilajnac, Nis, Leskovac, Prizren, and Pristina, where a UV index of 8 is expected. The highest value is forecast for Kopaonik, where the index reaches 9. On the mountain the risk is often greater than in the city, because the air is cleaner and the radiation stronger with every hundred meters of altitude.
High UV comes with heat. Maximum weekend temperatures range from 30 to 35 degrees Celsius, locally up to 36 on Sunday. That means the danger from the sun and the danger from overheating arrive at the same time, so your protection has to cover both problems.
How do you protect yourself, step by step?
The most important advice from doctors is simple: avoid direct sun between 10 a.m. and 5 p.m., when radiation is strongest. If you must be outside during that window, look for shade and keep your time in the open short.
Here are practical steps you can apply today:
- Apply a high-factor sunscreen, at least SPF 30 and ideally SPF 50, and reapply every two hours.
- Wear a wide-brimmed hat and UV sunglasses, because your eyes suffer from strong radiation too.
- Choose light, long-sleeved clothing in pale colors that covers the skin without overheating you.
- Drink water regularly, before you feel thirsty, to avoid dehydration and heatstroke.
Children, the elderly, and people with chronic conditions are especially at risk. Their unprotected skin reacts faster, and their bodies handle high temperatures less well. Babies under six months should not be in direct sun at all, a recommendation most pediatricians repeat.
Our advice is to plan the weekend around the sun, not against it. A morning walk before ten and a late afternoon after five are perfectly safe with sunscreen and a hat. The hours in between are for shade, water, and rest.
So, have you already packed your sunscreen and hat for this weekend, or will the sun catch you unprepared?
