Safety assessment for swimming in inland water bodies (rivers and dams): yellow flag – swimming is permitted only in guarded areas and in compliance with local rules, as these water bodies are not under constant supervision.

In the high parts of "Rila," "Pirin," and the "Stara Planina" (Balkan Mountains), maximum temperatures will be around 20–23°C at 1200 m and around 17–18°C at 2000 m, according to the NIMH forecast.
The probability of short rain showers with thunder in the afternoon is moderate – around 20–30%, mainly along ridges and peaks. The wind in high parts will be moderate to strong, eastern, with speeds of 8–12 m/s. Conditions for swimming in mountain lakes are not recommended – the water is cold, the areas are unguarded, and access is often difficult. Recommended assessment: red flag – swimming is not recommended.
Black Sea Coast
Along the "Black Sea coast" – from Durankulak to Rezovo – July 1st will be a typical summer day, with plenty of sun and high temperatures. Maximum temperatures along the shore will be around 28–31°C, with 28–30°C expected along the northern coast (Varna, Golden Sands, Balchik), and 29–31°C along the southern coast (Sunny Beach, Sozopol, Burgas, Ahtopol).

On guarded beaches, conditions for swimming are evaluated as good – green flag in most of the coastline, while following the instructions of lifeguards and protection from the strong UV index (level 8 – very high).
In summary, July 1st will offer stable summer weather throughout the country – sunny, warm, and suitable for the beach, walks, and outdoor activities.
