Surf Culture

Some people practice surfing as a recreational activity while others make it the central focus of their lives. Within the United States, surfing culture is most dominant in Hawaii and California because these two states offer the best surfing conditions. However, waves can be found wherever there is coastline, and a tight-knit yet far-reaching subculture of surfers has emerged throughout America. Some historical markers of the culture included the woodie, the station wagon used to carry surfers' boards, as well as boardshorts, the long swim shorts typically worn while surfing.
The sport of surfing now represents a multi-billion dollar industry especially in clothing and fashion markets. The Association of Surfing Professionals (ASP) runs the world tour, hosting only the best competitors in some of the best surf spots around the globe. Other people make a career out of surfing by receiving corporate sponsorships and performing for photographers and videographers in far-flung destinations; they are typically referred to as freesurfers.
When the waves were flat, surfers persevered with sidewalk surfing, which is now called skateboarding. Sidewalk surfing has a similar feel to surfing and requires only a paved road or sidewalk. To create the feel of the wave, surfers even sneak into empty backyard swimming pools to ride in, known as pool skating. Eventually, surfing made its way to the slopes with the invention of the Snurfer, later credited as the first snowboard. Many other board sports have been invented over the years, but all can trace their heritage back to surfing.

Surf Waves


Swell is generated when wind blows consistently over a large area of open water, called the wind's fetch. The size of a swell is determined by the strength of the wind and the length of its fetch and duration. Because of this, surf tends to be larger and more prevalent on coastlines exposed to large expanses of ocean traversed by intense low pressure systems.
Local wind conditions affect wave quality, since the surface of a wave can become choppy in blustery conditions. Ideal conditions include a light to moderate "offshore" wind, because it blows into the front of the wave, making it a "barrel" or "tube" wave. Waves are Left handed and Right Handed depending upon the breaking formation of the wave.
Waves are generally recognized by the surfaces over which they break. For example, there are Beach breaks, Reef breaks and Point breaks.
The most important influence on wave shape is the topography of the seabed directly behind and immediately beneath the breaking wave. The contours of the reef or bar front becomes stretched by diffraction. Each break is different, since each location's underwater topography is unique. At beach breaks, sandbanks change shape from week to week. Surf forecasting is aided by advances in information technology. Mathematical modeling graphically depicts the size and direction of swells around the globe.
Swell regularity varies across the globe and throughout the year. During winter, heavy swells are generated in the mid-latitudes, when the North and South polar fronts shift toward the Equator. The predominantly Westerly winds generate swells that advance Eastward, so waves tend to be largest on West coasts during winter months. However, an endless train of mid-latitude cyclones cause the isobars to become undulated, redirecting swells at regular intervals toward the tropics.
East coasts also receive heavy winter swells when low-pressure cells form in the sub-tropics, where slow moving highs inhibit their movement. These lows produce a shorter fetch than polar fronts, however they can still generate heavy swells, since their slower movement increases the duration of a particular wind direction. The variables of fetch and duration both influence how long wind acts over a wave as it travels, since a wave reaching the end of a fetch behaves as if the wind died.
During summer, heavy swells are generated when cyclones form in the tropics. Tropical cyclones form over warm seas, so their occurrence is influenced by El Niño & La Niña cycles. Their movements are unpredictable. They can move Westward as in 1979, when Tropical Cyclone Kerry wandered for three weeks across the Coral Sea and into Queensland before dissipating.
Surf travel and some surf camps offer surfers access to remote, tropical locations, where tradewinds ensure offshore conditions. Since winter swells are generated by mid-latitude cyclones, their regularity coincides with the passage of these lows. Swells arrive in pulses, each lasting for a couple of days, with a few days between each swell.
The availability of free model data from the NOAA has allowed the creation of several surf forecasting websites.

Hisotry Of Surfing



For centuries surfing was a central part of ancient Polynesian culture. Surfing might have been first observed by Europeans at Tahiti in 1767 by Samuel Wallis and the crew members of theDolphin who were the first Europeans to visit the island in June 1767. Another candidate is the botanist Joseph Banks being part of the First voyage of James Cook on the HMS Endeavour, who arrived on 10 April 1769 on Tahiti. Lieutenant James King was the first one who wrote about the art of surfing on Hawaii when completing the journals of Captain James Cook upon Cook's death in 1779.
When Mark Twain visited Hawaii in 1866 he wrote,
"In one place we came upon a large company of naked natives, of both sexes and all ages, amusing themselves with the national pastime of surf-bathing."
References to surf riding on planks and single canoe hulls are also verified for pre-contact Samoa, where surfing was called fa'ase'e or se'egalu (see Kramer, Samoa Islands) and Tonga far pre-dating the practice of surfing by Hawaiians and eastern Polynesians by over a thousand years.
George Freeth (November 8, 1883 – April 7, 1919) is often credited as being the "Father of Modern Surfing". He is also thought to have been the first modern surfer.
In 1907 the eclectic interests of land baron Henry Huntington brought the ancient art of surfing to the California coast. While on vacation, Huntington had seen Hawaiian boys surfing the island waves. Looking for a way to entice visitors to the area of Redondo Beach, where he had heavily invested in real estate, he hired a young Hawaiian-Irish athlete, George Freeth, to demonstrate the art of surfing.
As a child in Hawai’i, Freeth had seen an old Polynesian painting that depicted his mother’s ancestors riding surfboards. Freeth decided to revive the art of surfing But had little success with the huge 16-foot hardwood boards that were popular at that time. When he cut them in half to make them more manageable, he unwittingly created the original “Longboard", which made him the talk of the islands. To the delight of visitors, Freeth exhibited his surfing prowess twice a day in front of the Hotel Redondo.

Surfing

Surfing is a surface water sport in which the wave rider, referred to as a "surfer," rides on the forward face of a wave, which is most often carrying the surfer towards shore. Waves suitable for surfing are found primarily in the ocean, but can be found in some lakes, in rivers in the form of a standing wave or tidal bore. Surfing can also be done in manmade sources such as wave pools and boat wakes. The term "surfing" refers to the act of riding a wave and not the form (with or without a board) in which the wave is ridden. For instance, the native peoples of the Pacific surfed waves on alaia, paipo, and other such crafts on their belly, knees, and feet. Not to mention, Bodysurfing, the act of surfing a wave without a board, is considered by some to be the purest form of surfing. That much said, the more modern day definition of surfing tends to refer to when a surfer rides a wave standing up on a surfboard, which is referred to as stand-up surfing or paddleboarding. Although, another prominent form of surfing in the ocean today includes bodyboarding, which refers to when a surfer rides a wave either on the belly, dropknee, or stand-up on a bodyboard. Not to mention, knee boarding, surfmatting (riding inflatable mats), foils, bodysurfing, and so forth.
