Hey there! Have you ever watched surfers riding the waves and wondered how they do it? Well, there’s a lot of cool science involved in surfing, and it’s more than just balancing on a board. Let’s dive into the fascinating world of surfing science!
When surfers catch a wave, they’re actually using a bunch of physics concepts. Things like buoyancy, surface tension, mass, shape, and hydrodynamic forces all come into play. While the surfer’s mass and the shape of the board are important, buoyancy and hydrodynamic forces are all about the surfboard itself.
Surfboards have come a long way since the early days. Before the 1920s, surfboards were super heavy—sometimes over 100 pounds and up to 16 feet long! They were made from local woods like redwood, which weren’t very water-resistant. This meant the boards would soak up water, making them even heavier and harder to control.
In 1926, a man named Tom Blake from Wisconsin had a brilliant idea. He drilled holes into his redwood surfboard and covered it with thick pieces of wood. This made the boards lighter and easier to handle, and it became the first mass-produced surfboard. A few years later, in 1932, balsa wood boards came along, reducing the weight to just 30 pounds. Fixed tail fins were also added, making the boards more stable and easier to steer.
Surfboards stayed pretty much the same for a while, but recently, technology has taken them to the next level. Modern surfboards use materials like foam and fiberglass, making them lighter and stronger. New designs have made boards more hydrodynamic, which means they move through water more efficiently.
The shape of the board’s underside and the fins play a big role in how the board moves. Some boards have a double concave shape on the bottom, which looks like a wide “M.” This helps with a smooth ride. A V-bottom shape allows for easier turns, especially in larger waves. Fins work like spoilers on cars, balancing lift and drag to help control the board.
Believe it or not, surfboard makers can learn a lot from rocket science! Edison Connor, a former SpaceX engineer, co-founded a company called Burial Surf Technology. They use materials similar to those used in rockets to create surfboards. They’ve even developed a special kind of foam that crystallizes, forming tightly packed cells. This makes the boards lighter, more durable, and more buoyant.
It’s exciting to think about where surf technology will go next. Surfing isn’t the only sport that benefits from science, though. For example, in baseball, pitchers use physics to change how the ball moves by adjusting their grip and release. This makes it harder for batters to hit the ball.

Create a simple wave simulator using a shallow tray filled with water. Use your hand to generate waves and observe how they interact with objects like small boards or floating toys. Discuss how wave energy affects surfing and how surfers use it to ride waves.
Research the history of surfboards and create a timeline that highlights key developments in surfboard technology. Include images and descriptions of different materials and designs used over the years. Present your timeline to the class and discuss how each innovation improved surfing.
Imagine what surfboards might look like in the future. Use your knowledge of modern materials and technology to design a futuristic surfboard. Draw your design and write a short description of the materials and features that make it innovative.
Split into two groups and debate the statement: “The most important aspect of surfing is the technology of the surfboard.” One group will argue for the importance of surfboard technology, while the other will focus on the skills and techniques of the surfer. Use scientific concepts to support your arguments.

When I was a kid, I was obsessed with the movie *Blue Crush*, but as I got older, I realized that being a kid kind of crushed my dreams of being a surfer. But hey, at least the science of surfing is totally fascinating!
Hey everyone, Julia here for DNews. While athletes aren’t typically seen as nerdy types, there’s a lot of science that goes into sports—from using biology to optimize performance to using physics to create the perfect spin on a soccer ball. Surfing is no exception; there’s a lot more to it than meets the eye.
There’s a lot of physics at play when surfers hit the waves. Concepts like buoyancy, surface tension, mass, shape, and hydrodynamic forces all work together to create the perfect ride. While mass and shape tend to deal more with the surfer, buoyancy and hydrodynamic forces depend on the surfboard.
We’ve come a long way since the early days of surfing. Before the 1920s, surfboards were quite heavy—at least 100 pounds and up to 16 feet long. They were made of local wood, like redwood, but unfortunately, the wood wasn’t very water-resistant. As a person surfed, the boards would soak up water, becoming heavier and more difficult to control.
Then in 1926, a man from Wisconsin named Tom Blake decided to drill holes into his redwood surfboard and cover it with thick pieces of wood. This innovation became a huge hit and was the first mass-produced surfboard, although it was still big and heavy. A few years later, in 1932, balsa wood boards emerged, reducing the weight from 100 pounds to just 30. Shortly after that, fixed tail fins were added, making them more stable and easier to steer.
Surfboards pretty much stayed the same for a few decades, but recently, significant advancements have been made in technology. Foam and fiberglass have made surfboards lighter and stronger, and new designs have made boards more hydrodynamic. Hydrodynamics deals with how water moves around an object, so most of the magic happens underwater. The shape of the underside of the board and the shape of the fin influence how water is directed and how the surfer controls the board.
To achieve a smooth ride, some surfboards have two depressions on the bottom that look like a wide “M,” appropriately called double concave. A V-bottom has a V-shape in the middle of the board, which allows for easier turns and is good for larger surf. Fins, of course, are similar to spoilers on cars; they need to have the right balance between lift and drag.
Interestingly, surfboard makers can learn a lot from rocket science. Seriously! Former SpaceX engineer Edison Connor co-founded a company called Burial Surf Technology to create a board using the same materials used to make rockets. They even developed a new kind of foam that crystallizes, forming thick, tightly packed cells. This means more cells can be packed into the same area, resulting in a lighter, more durable, and more buoyant board.
So who knows where surf technology will take us next? It’s exciting to see how far it’s come in such a short amount of time. But you know what? Surfing isn’t the only sport that benefits from a solid understanding of science. Check out this video from Julian, who talks about the physics of baseball pitches. There’s a lot more to a pitch than just throwing the ball over the plate; by changing grip pressure and release, the pitcher can alter the ball’s flight path and challenge the batter.
