Weather in Burgas on September 21: More Sunshine and Stronger Winds

From Clouds to Sunshine: What's Changing the Weather in Burgas Today?

Hello, dear readers! We're starting the new work week with an interesting shift in the weather picture. While yesterday, Sunday, the sky over our coastline was mostly overcast, today, Monday, September 21, brings us much more sunshine and noticeably higher temperatures. After yesterday's cooler, cloudier picture, today we'll feel real autumn sunshine, albeit with more active air movement.

The Day in Stages: From Morning Fog to Afternoon Heat

Today will be marked by contrasts. In the morning, around 8:00 AM, fog will settle in, making the start of the day a bit more humid, with humidity at 86%. Temperatures at that hour will hover around 15.5°C. However, the fog will clear quickly, turning the day into a thoroughly sunny one — we're expecting about 10.9 hours of sunshine out of a possible 12.2.

Around midday, near 2:00 PM, we'll hit the day's peak. Temperatures will climb to an impressive 27.8°C, with the heat index feeling closer to 28.4°C. Humidity during this stretch will drop to 34%, making the air pleasant but dry. By evening, around 8:00 PM, it will stay clear and mild, with temperatures around 24°C and humidity at 53%. It's worth noting that the UV index will sit at 5.3, so caution is advised if you're planning to spend extended time outdoors.

Sea and Wind: Important News for Anglers and Beachgoers

Today's wind is the factor to watch. It will blow from the west at 21.1 km/h, with gusts that could reach up to 43.2 km/h. This westerly wind will bring a more dynamic atmosphere to Burgas Bay. For anglers and small boat owners, that means choppier seas compared to yesterday's easterly wind. Although the maximum wave height will stay low — around 0.2 meters — wind gusts could still stir up localized chop.

Sea water temperature remains very pleasant for the beach — around 24.9°C. Despite the stronger wind, the sea will be calm, making it a good day for the beach, as long as you keep in mind that the cooler wind could chill you quickly once you step out of the water.

Looking Back: A Historical Perspective

Looking through the archives, this date has proven quite variable over the years. In 2025, it was one of the warmest years on record for this day, at 25.5°C, while in 2016 the weather was much colder, reaching only 16.8°C. The average high for September 21 over past decades is around 21.3°C. Today's 28.9°C is well above that average, confirming the trend toward warmer autumn days.

Practical Tips for Your Monday

Since it's Monday and many of you will be out and about, here are a few recommendations:
• Clothing: Use the "layering" principle. You'll need a light jacket in the morning because of the fog and cooler temperatures, but a light summer outfit will do for the afternoon.
• Sports and walks: A great time for long walks along the coast, but be careful with wind gusts if you're planning to cycle.
• Driving: Watch out in the morning for lingering fog on roads around the city.
• Air quality: AQI stands at 39 — the air is good and completely safe for any activities.

Tomorrow, we're expecting brief showers and slightly lower temperatures. Stay tuned for tomorrow's forecast to plan your day perfectly!
