How do I check my swell at sea?

Swell speed is measured at nautical miles per hour or knots. (1 knot is 1.2 miles on land.) In order to work out the speed that a swell is travelling multiply the wave period by 1.5. The result is the speed the swell is travelling in knots.

How do you read a swell map?

The swell direction is usually expressed in cardinal points (N, E, S, W). As a general rule of thumb, a beach facing directly west will get bigger and better waves if the swell comes from the west. The swell direction is important — if the swell doesn’t hit your region correctly, you will not receive good waves.

How big do ocean swells get?

With a height of up to 29.1 meters (95 feet) from trough to crest, the single waves are the highest ever measured. In terms of so-called significant wave height, they established a new record, according to the scientists: 18.5 meters (61 feet). Significant wave height is the median height of a wave’s upper third.

Are waves in Hawaii big?

Pipeline, Waimea Bay & Sharks Cove, all found on the North Shore, are home to some of the largest waves you can see on the island of Oahu or even in the entire state of Hawaii. Most big waves average about 6-12 feet, with the really big waves reaching 30-50 feet.

How big are these waves raw Hawaiian swell?

From November to February, North Shore waves average heights of 16 feet, measured from the top to bottom of a wave’s “face”—the wave’s shore-facing side. For about 20 days during this peak season, waves swell to 36 to 50 feet in size. On occasion, our winter waves have topped 100 feet.

What month are the big waves in Hawaii?

The months between November and February are the best times to see big wave surfing. The massive waves can sometimes swell up to thirty feet or more—dangerous even for experienced surfers—so always heed warning signs.

What is the difference between surf and swell?

As swells arrives at the beach, shallow water forces waves to slow down and rise up above the surface, morphing as it goes through a process known as “wave shoaling”. Surf is swell that has arrived in shallow enough water to rise up above the surface, and break.

How old is the Pacific Ocean around Hawaii?

In the above figures, Hawaii is located just to the right of the words ‘Pacific, on the stripe labelled ‘34’: this magnetic stripe covers a very large age range, between 83 and 120 million year. The ocean floor around Hawaii is 100 times older than the island itself. The southeast Pacific is much simpler.

Why is Hawaii in the middle of the Pacific Ocean?

Hot spots do impact continents, as for instance in the Siberia and the Deccan traps. But it seems to fit Hawaii. This model can explain why Hawaii is where it is, in the middle of the Pacific ocean. It may even explain Iceland.

How big is the Pacific Ocean?

The expanse of water seems to go on forever. The Pacific ocean covers a third of the Earth surface, more than all the continents combined. The east-west width between Indonesia and Colombia is almost 20,000 km. There is 700 million cubic kilometer of water down there! 45 different countries own part of it.

What kind of map do you have for the ocean?

Pacific-Ocean wave (swell) map for surfers, windsurfers and sailors showing open ocean wave size, wave period and wave energy. You can customize the wave and wind maps with overlays for wind arrows, pressure and general weather for surfing.
