Swell: The Source of Waves<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What is Swell?<\/h3>\n\n\n\n<p>Swell is formed by wind blowing over the ocean, often thousands of kilometers from the shore. It is the primary generator of waves and can vary in size, power, and direction depending on wind intensity and the distance traveled by the waves.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to Read a Swell Forecast?<\/h3>\n\n\n\n<p>Two main elements to consider:<\/p>\n\n\n\n<ul>\n<li class=\" translation-block\">Swell size (measured in meters): A 1m swell can produce bigger or smaller waves depending on the spot, the underwater topography, and local conditions.<\/li>\n\n\n\n<li class=\" translation-block\">Period (measured in seconds): A long period (&gt;12s) means more powerful and well-spaced waves, while a short period (&lt;8s) results in weaker, more frequent waves.<\/li>\n\n\n\n<li class=\" translation-block\">However, the period does not just define wave power. The longer the period, the better the swell can wrap around natural obstacles like islands, reefs, or sandbanks. This allows certain swells to reach sheltered spots, often considered fallback options, that may be more difficult to access.<\/li>\n\n\n\n<li>These less exposed spots, usually unaffected by short and messy swells, can deliver unexpectedly high-quality waves when the period is long enough.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"324\" height=\"169\" src=\"https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/Capture-decran-2025-02-24-a-12.04.30.png\" alt=\"\" class=\"wp-image-43017\" srcset=\"https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/Capture-decran-2025-02-24-a-12.04.30.png 324w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/Capture-decran-2025-02-24-a-12.04.30-300x156.png 300w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/Capture-decran-2025-02-24-a-12.04.30-18x9.png 18w\" sizes=\"(max-width: 324px) 100vw, 324px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Swell Direction and Its Influence<\/h3>\n\n\n\n<p>Swell direction plays a crucial role: some spots only work with specific swell orientations. For example, a north-facing spot will best catch a north swell, while a west-facing spot will be ideal for Atlantic swells. On the Atlantic coast, weather disturbances influence wind direction and strength, though thermal winds also play a role, particularly in Portugal.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"1024\" height=\"448\" src=\"https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-1024x448.jpg\" alt=\"Vent meteo surfhouleMar\u00e9e infoWildsuits\" class=\"wp-image-43013\" srcset=\"https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-1024x448.jpg 1024w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-300x131.jpg 300w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-768x336.jpg 768w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-1536x673.jpg 1536w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-18x8.jpg 18w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02-600x263.jpg 600w, https:\/\/wildsuits.eu\/wp-content\/uploads\/2025\/02\/meteo-02.jpg 1861w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2.

For example:<\/p>\n\n\n\n<ul>\n<li>Beach breaks (sandy beaches): Often best at mid-tide rising.<\/li>\n\n\n\n<li>Reef breaks (rocky reefs): Require specific tides to expose or cover rocky sections.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Case Study: Spot Comparison<\/h3>\n\n\n\n<p class=\" translation-block\">In Hossegor (France), tides heavily impact the shape of sandbanks. A perfect sandbank at low tide may not work at high tide. Conversely, in Biarritz, some reef breaks only function at high tide. <a href=\"https:\/\/maree.info\/\" target=\"_blank\" rel=\"noreferrer noopener\">maree.info<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4.
