Playing golf at varying altitudes has a significant impact on the distance a golf ball travels. At higher altitudes, golf balls travel further due to thinner air exerting less drag force, which means the ball moves through the air more easily and doesn't slow down as quickly. Conversely, playing golf at sea level results in shorter distances due to denser air. For example, a golfer in San Diego at sea level who hits a 250-yard drive will experience an increase in distance to approximately 265 yards when playing in Denver, which is around 5,280 feet above sea level. This effect is further influenced by factors such as temperature and spin rate, with an increase in spin rate observed at higher altitudes.

What You'll Learn
Golf ball distance is greater at sea level
Golf ball distance is greater at higher altitudes due to the thinner air, which exerts less drag force on the ball. This means the ball moves through the air more easily and doesn't slow down as quickly, resulting in greater distance. For example, a golf ball that travels 250 yards at sea level will travel about 270 yards at 7,000 feet above sea level, an increase of 20 yards. This increase in distance is not due to an increase in spin; in fact, the optimal spin rate with a driver increases from 2,250 RPMs at sea level to about 3,000 RPMs at 10,000 feet.
The effect of altitude on golf ball distance can be significant, especially for professional golfers. For example, at 1,500m altitude, an amateur player's distance may increase by up to 7%, while a professional PGA Tour player's distance can increase by up to 9%. Irons 6, 7, and 8 make the biggest difference in distance at higher altitudes, with iron 7 being the most decisive club.
The impact of altitude on golf ball distance is also influenced by other factors such as temperature and wind. For example, for every 10 degrees of temperature change, the carry change increases by about half a yard between a pitching wedge and a driver, capping out at about two yards. Wind can also affect the distance a golf ball travels, but its impact is separate from the effects of altitude.
When playing golf at sea level, the distance a ball travels is limited due to the thicker air, which exerts more drag force on the ball. This is why golfers who are used to playing at higher altitudes may feel humbled when they play at sea level, as they do not get the same distance on their shots. However, it is important to note that other factors besides altitude can affect the distance a golf ball travels, such as swing speed and equipment changes.

Thinner air at higher altitudes exerts less drag force on the ball
Golf is a sport that can be significantly affected by changes in altitude. The distance a golf ball travels at sea level is limited due to the thicker air found at lower altitudes. Conversely, at higher altitudes, thinner air exerts less drag force on the ball, allowing it to travel further.
The impact of altitude on golf ball distance can be observed by comparing measurements at sea level and higher altitudes. For instance, an amateur golfer's performance was measured at sea level (0 meters above sea level) and then at an altitude of 1,500 meters. While the exact figures are not provided, it is noted that the increase in distance was less than the expected 10%.
The difference in distance becomes more pronounced for professional golfers. In one example, a professional PGA Tour player's distance increased by up to 9%, which is still less than the anticipated 10%. Irons 6, 7, and 8, especially iron 7, were the clubs that showed the most significant differences in performance with altitude changes.
The relationship between altitude and golf ball distance can be further understood through another example. Typically, a golfer who consistently drives the ball a distance of 250 yards at sea level in 70-degree conditions will experience an increase in distance at higher altitudes. At the Club de Golf Chapultepec in Mexico, which sits at an elevation of around 7,000 feet above sea level, the same golfer can expect their drive to increase to approximately 270 yards.
The effect of altitude on golf ball distance can be attributed to the change in air density. As altitude increases, air density decreases, resulting in thinner air that exerts less resistance on the ball. Consequently, the ball moves more effortlessly through the air and maintains its speed for longer, leading to increased distance. This phenomenon is not unique to golf; it also occurs in other sports, such as football, where NFL kickers can achieve longer kicks at high-altitude stadiums.

Spin rate increases at higher altitudes
Spin rate is a crucial factor in golf course management strategies. The spin rate is the amount of spin that occurs right after a golf shot is hit, and it is measured in RPM. Spin rates differ depending on the club used, with higher lofted clubs resulting in higher spin rates. Spin rates can be increased by teeing the ball higher, keeping one's weight back during the downswing, and using heavier shafts.
Spin rates play a significant role in how a golf ball flies through the air and behaves. A high spin rate leads to a higher launch angle, making it feel like the ball is floating before dropping back onto the green. Conversely, a lower spin rate results in a lower trajectory and landing angle.
While a certain amount of spin is necessary to generate lift, excessive backspin can cause the ball to fly high but not far. Similarly, low backspin can reduce control and stopping power. Sidespin, which occurs when the clubface is not square to the swing path at impact, can lead to hooks and slices, throwing shots off course.
At higher altitudes, the optimal spin rate increases due to thinner air, which reduces the force on the ball and results in a lower lift force. This leads to a flatter trajectory and a more shallow angle of descent, allowing the ball to roll further. Therefore, when playing at higher altitudes, golfers may need to adjust their spin strategies to account for the change in air density.

Golfers need to adjust to new elevations
The higher the elevation, the thinner the air, and the longer the ball will travel. This is due to the change in air density, which decreases as elevation increases. Thinner air exerts less drag force on the ball, so it moves more easily through the air and doesn't slow down as quickly, resulting in greater distance. For example, a golf club that usually hits 150 yards at sea level might now go 160 yards at a higher elevation.
The optimal spin rate with a driver increases from 2,250 RPMs at sea level to about 3,000 RPMs at 10,000 feet. This is because the air is less dense at increased altitudes, so the importance of hang time increases.
Golfers can use a simple formula to adjust their distances when playing at new elevations. For instance, if you usually hit a 250-yard drive in San Diego (sea level), you can expect to hit it about 265 yards in Denver (elevation of 5,280 feet). The calculation is as follows: 5,280 feet (Denver's elevation) x 0.00116 = 6.12%. Multiply your average drive of 250 yards by 6.12% to get an updated average driving distance of 265 yards.
It's worth noting that while elevation can impact distance, it does not affect the spin of the ball.

Sea level courses limit distance due to thicker air
Sea level golf courses limit distance due to thicker air. This is a result of the change in air density, which decreases as elevation increases. When compared to higher altitudes, the air at sea level is denser and exerts more drag force on the ball, causing it to slow down faster and travel shorter distances.
The impact of elevation on the distance a golf ball travels can be significant. For example, an amateur player measured their distance while playing at sea level and then again at 1,500 meters above sea level. The results showed a surprising difference, with the ball travelling further at higher altitudes. This effect is even more pronounced for professional golfers, with irons 6, 7, and 8 making the biggest difference in distance.
The formula for calculating the impact of altitude on distance is simple: multiply the elevation in feet by 0.00116 to get the percentage increase or decrease in distance. For every 1,000 feet of altitude, you can expect approximately 2.5 extra yards of distance. This is because the thinner air at higher altitudes exerts less drag force on the ball, allowing it to stay in the air longer and travel further.
However, it's important to note that other factors, such as temperature and wind, can also affect the distance a golf ball travels. Additionally, the impact of altitude may be less noticeable for irons and wedges. Nevertheless, playing at sea level can be a humbling experience for golfers accustomed to higher elevations, as they may need to adjust their expectations and strategies accordingly.
Understanding the impact of sea level on golf distance can help golfers adjust their game when playing at different elevations. By considering the denser air and increased drag force at sea level, golfers can make the necessary adjustments to their swing, club selection, and strategy to optimise their performance at any course.
