Understanding the Science Behind Surfing Waves

Surfing is a journey of continuous learning and adaptation. From mastering the basics as a beginner to performing advanced maneuvers, each stage of progression brings new challenges and rewards. Whether you are a beginner catching your first wave in Kandui resort surf or an advanced surfer tackling a challenging reef break, the right knowledge equips you to make informed decisions and enjoy the thrill of surfing to its fullest. You can start by learning about the waves. 

How Waves are Formed

Waves are formed by the wind as it blows across the surface of the sea. The process begins far out at sea, where the wind transfers its energy to the water, creating ripples. As these ripples travel across the ocean, they grow into waves due to the continued energy transfer of the wind. 

As these waves travel towards the shore, they interact with the seabed, causing them to slow down and increase in height. This transformation creates the surfable waves that break near the coast. The contour of the ocean floorplays a crucial role in determining how a wave will break.

Several factors influence wave formation:

Wind speed. This refers to how fast the wind is blowing across the surface of the ocean. The speed of the wind is directly proportional to the energy it transfers to the water. When the wind blows across the surface of the ocean, it creates friction between the air and the water. This friction causes small ripples to form. As the wind continues to blow, these ripples grow larger and develop into waves.

  • Low Wind Speed. When the wind speed is low, the energy transfer is minimal, resulting in small, gentle waves. These conditions are often ideal for beginners or longboarders in Kandui resort surf who prefer less powerful waves.
  • High Wind Speed. When the wind speed is high, more energy is transferred to the water, creating larger, more powerful waves. These waves are preferred by experienced surfers looking for challenging conditions.

Wind duration. This is the length of time the wind blows over the water surface. The longer the wind blows, the more energy is transferred to the water, allowing waves to grow larger and more powerful.

  • Short Duration. If the wind blows for a short period, the waves do not have enough time to grow significantly. This results in smaller, less well-formed waves.
  • Extended Duration. When the wind blows consistently over an extended period, the waves have more time to absorb energy and grow. This results in larger, more powerful waves that can travel long distances.

Fetch. It is the distance at which the wind blows uninterrupted across the water surface. A longer fetch allows more time and space for waves to develop and gain energy.

  • Short Fetch. With a short fetch, the waves do not have enough distance to grow significantly. The waves generated are typically smaller and less powerful.
  • Long Fetch. A long fetch provides a vast area over which the wind can blow, allowing waves to grow larger and more organized. The longer the fetch, the more time the wind has to transfer energy to the water, resulting in larger, more powerful waves.

Additional Factors

Beyond wind speed, duration, and fetch, other factors can influence wave formation:

  • Water Depth. As waves approach the shallower waters of the Kandui resort surf, they slow down and increase in height. This process is known as shoaling. The contour of the seabed determines how waves break.
  • Currents and Tides. Ocean currents and tidal changes can affect wave height and shape. For example, incoming tides can increase wave height, while outgoing tides may decrease it.
  • Geographical Features. Coastal geography, such as the presence of islands, peninsulas, or underwater reefs, can affect wave direction and intensity. These features can either block waves or funnel and amplify them.

Types of Waves

Waves break in various ways depending on the underwater topography of the coastline. There are three primary types of waves that surfers encounter:

Point breaks 

One of the defining characteristics of point breaks is their length. Unlike waves at beach breaks, which may break abruptly and close out quickly, waves at point breaks can travel considerable distances along the coastline. This length allows surfers of the Kandui resort surf to enjoy long, uninterrupted rides, maximizing their time on the wave and providing a thrilling and fulfilling surfing experience.

Despite their popularity, surfing a point break requires skill and patience. Surfers must carefully position themselves in the lineup to catch the waves at the optimal point, where they begin to peel along the shoreline. Timing is crucial, as mistimed paddles or late take-offs can result in missed opportunities or wipeouts. 

Reef Breaks

One of the defining features of reef breaks is their power. Because the waves are forced to rise quickly over the shallow reef, they can generate significant energy and speed. This makes reef breaks particularly exhilarating but also demanding for surfers in Kandui resort surf, who must be able to handle the intensity of these waves. The quick rise and steep face of reef break waves often create the perfect conditions for barrel riding, where the wave forms a hollow tube that surfers can ride through.

The shape of reef break waves is heavily influenced by the specific contours and depth of the reef. Reefs with abrupt drops can produce hollow, barreling waves that are prized by surfers looking for the ultimate adrenaline rush. Conversely, reefs with more gradual slopes might produce softer, rolling waves that are still powerful but less likely to form barrels. 

Beach Breaks

One of the main characteristics of beach breaks is their variability. The shifting sands that form the seabed at beach breaks are constantly moved by tides, currents, and wave action. This movement creates and alters sandbars, which are the features that shape the waves. As a result, beach breaks can produce a wide variety of waves, from gentle rollers to steep, hollow barrels. 

Beach breaks are often more accessible than other types of breaks. They are typically found along sandy shorelines of the Kandui resort surf, which are common and easy to reach. This accessibility makes beach breaks popular spots for beginner surfers, who can practice and learn in a relatively forgiving environment. The sandy bottom is generally safer than the rocky or coral reefs found at reef and point breaks, reducing the risk of injury during wipeouts. This makes beach breaks an ideal setting for surf schools and novice surfers to develop their skills.
