Belgrade Forecast: Rain and 18 Degrees on Tuesday
RHMZ forecasts rain and a high of just 18 degrees in Belgrade on Tuesday, with thunderstorms expected in southern and southwestern Serbia. Here is the day by day outlook through the end of the week.

Should you carry an umbrella on Tuesday? The short answer is yes. Serbia’s Republic Hydrometeorological Service (RHMZ) is forecasting rain and a high of just 18 degrees in Belgrade, following several days of noticeably warmer weather.
Yesterday we reported that summer was loosening its grip, when RHMZ announced a temperature drop of more than 10 degrees. The latest forecast, issued today at 11:15, shows just how real that drop is turning out to be. Today, Monday, most of Serbia is seeing moderate to overcast skies, with brief rain in places, while a thunderstorm is possible in the southwest and south of the country. Winds are light to moderate, occasionally strong, blowing from the northwest and easing by evening. Today’s highs range from 22 degrees in the north to 27 in the south and east of the country.
RHMZ’s forecast for today states:
Gradual clearing is expected in the north around midday, and in the western, central and eastern regions in the afternoon.
In the southwest and south of Serbia, the agency adds, there is still a chance of brief rain or a thunderstorm, while the rest of the country clears up by midday and into the afternoon.
What weather is coming through Friday
Here is RHMZ’s day by day outlook for Belgrade:
- Monday, September 21: cloudy, low of 12, high of 24 degrees
- Tuesday, September 22: rain, low of 10, high of just 18 degrees
- Wednesday, September 23: cloudy, high of 20 degrees
- Through Friday, September 25: cool mornings, daytime highs between 18 and 25 degrees, variable cloudiness with sunny spells and occasional local brief rain or showers
The picture is similar across the rest of Serbia. The north stays a touch cooler, the south and east a touch warmer, but the same rule holds everywhere: after Monday, temperatures head down and rain comes back into play.
What to wear and what to watch for
Tuesday is not a day for sandals or short sleeves. A few practical pointers for Tuesday and the days after it:
Upside: Monday afternoon looks, based on this forecast, like a good window for a short walk, since the western, central and eastern regions clear up by midday and into the afternoon.
Downside: for Tuesday, plan seriously on an umbrella or a waterproof jacket. The rain that day is not occasional, it is forecast to last the whole day, alongside a drop to just 18 degrees.
- dress in layers, mornings and evenings are considerably colder than midday, with a difference of up to 10 degrees
- if you are traveling through southern or southwestern Serbia, expect thunder, a storm there can arrive suddenly
- for Wednesday and the days through Friday, an autumn jacket is enough, no umbrella needed, unless you happen to catch the local shower RHMZ mentions as a possibility
For now, there is no sign of a sudden change after Wednesday. Through the end of the week, RHMZ forecasts variable cloudy weather with sunny spells and temperatures between 18 and 25 degrees, with occasional brief rain through Friday. In other words, autumn has officially arrived in the forecast, not just on the calendar.
