The two types of wind
On the Dune du Pilat (Pyla), two types of wind predominate:
The thermal breezeA sea breeze, also known as a sea breeze, forms when the land warms up faster than the ocean during the day. This process creates a difference in atmospheric pressure between the land and the ocean, generating a flow of air from the ocean to the land.
The weather wind is generated by pressure differences on a regional or global scale, often due to temperature variations between regions and the Earth's rotation. These pressure variations cause large-scale air movements, creating weather systems such as depressions and anticyclones, which influence the wind over greater distances and for longer periods than thermal breezes.
In this article, we explore the complex dynamics of winds, highlighting the interaction between the local thermal breeze and the larger-scale meteorological wind.
Sea Breeze Explained
Sea breezes generally occur during the day, usually from 12 to 2pm. This phenomenon is closely linked to the absorption of solar radiation by the earth. When the sun reaches its zenith and the earth begins to absorb heat intensely, a significant temperature difference is created between the land and the sea. This temperature disparity causes a variation in atmospheric pressure between the two zones, giving rise to the sea breeze.
The sea breeze generally starts to appear towards the end of the morning and increases in strength as the afternoon progresses, generally reaching its peak between 2pm and 5pm, depending on the specific exposure of the area. However, it is essential to note that this phenomenon can vary considerably depending on a number of complex parameters and can sometimes occur earlier or later than expected.
The sea breeze is also known as the "maritime thermal" because of its close link with the heat of the ocean.
Wind Weather Explained
The wind in the Arcachon Basin region is closely linked to atmospheric pressure and overall weather conditions. When the area is under the influence of a high-pressure system, the weather is generally calm, with light winds, creating optimum conditions for paragliding. However, if the anticyclone shifts to the EAST, the wind can come from the land to the sea, which is not favourable. Similarly, if the anticyclone stagnates for too long and the air becomes too warm and stable, the possibility of flying is sometimes wiped out for several weeks.
Why do sea breezes occur during the day?
Sea breezes generally occur during the day, usually from 12 to 2pm. This phenomenon is closely linked to the absorption of solar radiation by the earth. When the sun reaches its zenith and the earth begins to absorb heat intensely, a significant temperature difference is created between the land and the sea. This temperature disparity causes a variation in atmospheric pressure between the two zones, giving rise to the sea breeze.
When does the sea breeze blow?
The sea breeze generally starts to appear towards the end of the morning and increases in strength as the afternoon progresses, generally reaching its peak between 2pm and 5pm, depending on the specific exposure of the area. However, it is essential to note that this phenomenon can vary considerably depending on a number of complex parameters and can sometimes occur earlier or later than expected. Because of this variability, anticipating and forecasting sea breezes can be quite difficult.
What is the sea breeze called?
The sea breeze is also known as a "sea breeze". marine thermal "Because of its close link with ocean temperature.
Sea Breeze Explained: An Educational Video
This video tutorial highlights how sea breezes are influenced by local and thermal phenomena, such as the variation in air temperature near the coast and the pressure difference between land and sea.
Wind and weather explained simply
Le weather wind is directly influenced by atmospheric pressure and general weather conditions. When the region is under the influence of a anticycloneThe weather is generally calm, with light winds, providing ideal conditions for paragliding. On the other hand, when depression approachesthe wind can become more fort and unstablemaking the flight more difficult and less safe. That's why it's essential to monitor local weather forecasts.

Optimal Wind Conditions for Paragliding
Paragliding flights are best when the wind is blowing ideally from the north-west. However, flights are also possible when the wind comes from the north to the west-south-west, with an angle between 247° and 0°. This orientation depends on various parameters and exceptions. We use weather model comparisons to improve the accuracy of our forecasts. The ideal season for paragliding is from early April to end September.

Wind Speed and Direction :
When planning your paragliding flight, understanding the wind speeds and directions you are looking for is essential for a safe and enjoyable flying experience. Here's what you need to know:
Wind Speed : For optimum flying conditions, we generally look for average wind speeds of between 15 and 20 kilometres per hour, sometimes up to 45-50kmh. Weaker winds can make flying difficult to control, while stronger winds can become dangerous, especially for beginners. We keep a close eye on the weather forecasts to ensure that the winds stay within this ideal speed range.
Wind direction : Wind direction is also a crucial factor. We mainly look for winds from the north-west. However, winds from the north to the west-south-west, i.e. within a range of 247° to 0°, are also considered favourable. These wind directions offer the best conditions for slope flying along the dune.
Where can I check the wind conditions?
For the most accurate information on real-time wind conditions on the Dune, you can consult the dedicated weather beacon on the FFVL website. This beacon provides updated data on the speed and the direction wind, although we recommend that you also consult other meteorological sources to minimise the risks associated with possible variations or inaccuracies. By keeping an eye on wind speeds and directions, you can maximise your chances of enjoying a safe and exciting paragliding flight at the Dune du Pilat.
Additional information :
However, it is important to note that the weather beacon can sometimes provide incorrect or inaccurate data. We use it as a second real-time analysis tool, but it is not 100% reliable. We therefore recommend that you also consult other weather sources to minimise the risks associated with any variations or inaccuracies.

The Keys to Aerology in the Arcachon Basin
The success of a safe flight depends on a detailed understanding of the aerological conditions specific to this very special site.
- At the Dune du Pilat, air density plays a crucial role in flight planning. When the air is cooler, its density increases, reducing the wind needed to maintain sufficient dynamic lift. This knowledge helps pilots to choose the ideal moment to fly, minimising the risk of unexpected turbulence.
- In addition, the particular terrain creates complex variations in the wind. Close to the ground, the wind can be affected by the roughness of the terrain and temperature differences between land and sea. Experienced pilots know how to interpret these subtle signals to find the safest take-off and landing zones.
- The unique topography also offers unique opportunities for dynamic lift. The steep slopes and distinctive shape of the dunes encourage the formation of updrafts, offering pilots the chance to extend their flights with ease.
- Flying over the Massif du Pyla is not without its challenges. Strong winds can intensify turbulence, especially near the surrounding hills and cliffs. A thorough understanding of these phenomena is therefore essential to ensure safe flying.
Finally, external factors such as sunshine and tides influences the breeze due to the temperature contrast between land and sea. As the tide rises, the colder seawater cools the beach, creating an area of relative low pressure. Warm air from the hinterland moves towards this zone, forming the sea breeze blowing from the sea towards the land. At low tide, the process reverses, creating a land breeze from the hinterland to the sea. This phenomenon influences the strength and direction of the wind.
