Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Sunny Beach, on Bulgaria’s Black Sea coast in Burgas Province, is a long sandy resort known for its gently shelving shoreline and popular summer season. Water temperatures follow a clear seasonal pattern: in winter (December–February) surface values are typically around 7–9 °C, spring (March–May) brings a gradual rise to roughly 10–18 °C, summer (June–August) usually offers the warmest conditions at about 21–27 °C, and autumn (September–November) sees cooling to roughly 16–22 °C. These averages mean the sea becomes comfortably warm for most visitors from late May through September, while outside that window the Black Sea is considerably cooler and more suited to brisk swims or short dips rather than long bathing sessions.

Swimming Conditions
Swimming and beach holidays at Sunny Beach are shaped by those temperature patterns and by the resort’s infrastructure. The long, shallow gradient makes the water accessible and generally safe for families and less confident swimmers during warm months; lifeguard services, marked swimming zones and plentiful beach amenities support a classic seaside experience. From June to August the sea is at its most inviting for prolonged swimming, casual snorkeling and non-motorised water sports, while September often still provides pleasant bathing conditions with fewer crowds. Outside the main season many hotels maintain pools heated to allow swimming even when the sea is cool, but seawater swims are best planned for the warmer months when temperatures reach the mid-20s °C.
