Beach flags: what they really mean

If you go to the beach and think that flags are only there for show… perhaps it's time to take a closer look. Those flags flying near lifeguard towers or at the entrances to beach resorts are not, in fact, decorative: they are safety signals, and knowing what they mean can truly make a difference.

The white flag has been replaced by the green one, and the reason is simple: white is not very visible from a distance, especially on very bright days. Green, on the other hand, is immediately noticeable and clearly communicates that the sea is calm and swimming is safe (for further details: circular from the General Command of the Port Authorities, issued on April 16, 2025).

Beach flags therefore become like traffic lights on the road: they are not there to restrict you, but to protect you, with a language that is more universally understood.

✅ GREEN FLAG

Lifeguard service active, favorable conditions

Calm sea, ideal conditions for swimming.
The rescue service is active and operational.
Feel free to go into the water, but always with caution.

⚠️ YELLOW FLAG

Service active, potentially risky weather and sea conditions

Warning: rough sea or strong wind.
Swimming is not prohibited, but conditions require caution.
It is often also a signal to remove umbrellas and deckchairs for safety.

❌ RED FLAG

Swimming discouraged or dangerous, with or without active service

Swimming prohibited or strongly discouraged.
The sea may be dangerous or there may not be an active rescue service.
In some cases, those who enter the water do so at their own risk.

With the addition of a sign, it can indicate the total absence of supervision or a swimming ban for hygiene and health reasons (e.g., polluted water).
If you see this combination, it's best not to improvise.

👁🗨 Small details that make a difference

• Flags must be clearly visible and placed in strategic locations.

• Each establishment must display them correctly based on the actual sea conditions.

• The lifeguard plays a fundamental role in deciding which color to hoist: it's not random, it's a responsibility.
