Night cooling
The Babadag slopes lose heat quickly at night. As the air over land cools, it becomes denser and flows downhill toward the sea. This drainage continues until sunrise or until the slopes warm up.

Land breeze and Oludeniz landing safety
Landings at Oludeniz are made from sea to land. The land breeze — wind blowing from land toward the sea — is a tailwind on this approach and makes landing dangerous. This guide explains when the land breeze appears, how to recognise it and what to do for a safe landing.
What is the land breeze?
The land breeze is wind that flows from land toward the sea when the air over land is colder than the air over the sea. At Oludeniz this happens during the night and early morning: until the Babadag slopes warm up in the sun, cold air drains down the mountain and out over the sea. The wind comes from approximately 320–120 degrees (northwest, north, northeast and east).
This is the opposite of the sea breeze, which blows from sea to land in the afternoon and creates a headwind on the landing approach — the ideal condition. The land breeze creates a tailwind and is always more dangerous.
Why does it appear every morning?
Valley flow
Cold air draining from the north and south slopes of Babadag reaches the Oludeniz beach through valleys. This local flow can be strong even when there is no large-scale wind.
Air mass changes
During frontal passages or overnight high-pressure buildups the land breeze is more pronounced and stronger. These conditions show up in the model, but the local effect can be stronger than the model predicts.
Why is a tailwind on landing dangerous?
Landings are made from sea to land — the pilot comes in over the sea and descends toward the landing area on the beach. Normally the wind is a headwind (sea breeze), which slows the ground speed and makes the flare short and controlled. With a land breeze, the wind is from behind:
| Condition | Wind direction | Effect |
|---|---|---|
| Sea breeze (afternoon) | Sea to land (headwind) | Ideal: speed drops, flare short, controlled |
| Land breeze (morning) | Land to sea (tailwind) | Dangerous: speed increases, flare long, overshoot risk |
| No wind | — | Neutral: pilot manages own speed |
A 5 km/h tailwind adds roughly 10 km/h to ground speed. This increases the risk of overshooting into trees, fences or seating areas at the end of the landing zone.
What to do for a safe landing
- Know the land breeze direction: If the wind is from 320–120 degrees, the land breeze is active. The Babadag weather site labels this as "Land breeze direction" on the landing card.
- Watch the speed threshold: Even under 5 km/h, be careful. 5–12 km/h is risky — tighten the pattern, shorten the approach. 12 km/h and above is not safe.
- Check the gust: Land breeze gusts can be sudden and sharp. A 10 km/h gust makes landing difficult; 15 km/h closes the landing.
- Watch for direction change: The transition from land breeze to sea breeze is marked by a sudden wind direction shift. Conditions change rapidly during this transition — the site issues a "Sea breeze front" warning.
- Ask the on-site official: The Meteorological Evaluation Board and field officials know local effects the model cannot see. The official decision always overrides the model assessment.
Frequently asked
Does the land breeze happen every morning?
At Oludeniz, most mornings have a light land breeze. In summer it is shorter and lighter; in autumn and winter longer and stronger.
Does the model predict the land breeze correctly?
The model gets the direction approximately right but can underestimate the strength. Babadag's topography amplifies the local flow; the site therefore always shows at least Risk for land breeze directions.
Does the land breeze end when the sea breeze starts?
Yes, the sea breeze (afternoon, sea to land) overcomes the land breeze. This transition usually happens around midday and landing conditions become safe.
