Weather in Burgas on September 23: Autumn showers and calm sea

Autumn Mood over Burgas

Today, autumn is starting to show its teeth, but without scaring us. After yesterday's cloudy day, today in Burgas we will be greeted by brief showers. There is no need to worry about getting wet – the rains will be transient, but an umbrella will certainly not be unnecessary if you are planning a walk.

Temperatures will be moderate, between 14 and 19°C, although due to humidity it will feel a little cooler, around 16°C. The sun will appear for about 9 hours out of the 12 available, so it won't be completely gray, but the clouds will be playing «hide and seek» with the sky.

Will it rain?

Yes, we expect about 2.5 mm of precipitation. The probability of rain is around 35%, so it will rather be intermittent showers that won't completely disrupt your plans.

Is the beach an option?

If you love swimming in warm water, the sea is still yours. The water temperature is around 24°C, which is wonderful for September. The waves are very small – barely up to 0.4 meters, so the sea is calm. Just watch out for the wind, which will blow from the northwest at a speed of about 17 km/h, with gusts up to 36 km/h in some places. These gusts might make you feel a little colder while you are on the shore.

How is it for driving?

The roads will be wet due to the showers, so drive carefully, especially if you are heading out early in the morning. Visibility is good, but it is a good idea to have your lights on.

How the day changes

In the morning, around 08:00, it will be quite cloudy and humid – about 77% humidity at 14°C. By noon (around 14:00), the clouds will disperse and we will feel a little more warmth, around 18°C, and humidity will drop to 50%. In the evening (around 20:00), the sky will become mostly clear and cool down to 17°C, which is ideal for a calm walk along the coastal promenade.

Marine details

The calm water and moderate temperature of 24°C are excellent for marine life. When the sea is this quiet and warm, it usually means there are no large waves to disturb the bottom, and the plankton is in good condition. It is a good moment for fishing, and for swimmers – the sea is still very welcoming. There are no signs of storms that would bring jellyfish or other unexpected guests into the bay.

And in previous years

If we look at the archives, today's date is quite interesting. In 2025, it was much warmer – reaching up to 25°C without rain. In comparison, in 2006, a serious umbrella was required with almost 28 mm of precipitation. On average for September 23 over recent years, temperatures reach around 20°C. It can be said that today's 19°C is quite normal, slightly below the historical average.

Practical tips

For today, I recommend layered clothing – a light jacket or a sweatshirt will protect you from the wind and moisture. If you are planning outdoor sports, it is better to choose the late afternoon when the clouds disperse. The air quality is very good (AQI 27), so it is a great day for a long breath of fresh sea air.

Tomorrow it will clear up more and will have scattered clouds, and temperatures will rise to 22°C. Expect me with an even more pleasant forecast!
