Golf Ball Performance and Temperature

By Frank ThomasDecember 24, 2009, 12:30 am
Frank,
I really enjoy reading your Q&A every week, so please keep it going. My question relates to the effect that air temperature has on ball flight. I’ve noticed that a 20 degree F difference in temperature can substantially affect the distance on my shots. In some cases, I’ve even found this when playing on consecutive days when the temperature is very different, I need to be careful about club selection.

How does temperature impact the ball? Is there an ideal temperature range that golf balls are designed to be played in?

Thanks,

– Brendan

Brendan,

Many golfers – even the pros – don’t pay enough attention to the air temperature when selecting a club for a particular shot. The ball temperature also affects its resilience properties, but not as much as the air temperature.

As air temperature increases, the air becomes less dense, and this is why it is more difficult for airplanes to take off on hot days than cold days. The lift forces are reduced in hot (less dense) air, as are the drag forces – and the overall effect is that balls will travel farther on hot days than cold days.

A general rule of thumb is to estimate a 2 to 2.5 yard difference for every 10° F. So at 40° F, the ball will travel about 10 to 12 ½ yards less than at 90° F. In combination with your decreased body temperature, which will have some effect on your swing, this could add up to something significant -- at least one to one and a half clubs’ difference in your selection.

Hope this helps warm you up for the next cold day on the course.
 
Merry Christmas!

Woods favored to miss Farmers Insurance Open cut

By Will GrayJanuary 24, 2018, 1:54 am

If the Las Vegas bookmakers are to be believed, folks in the San Diego area hoping to see Tiger Woods this week might want to head to Torrey Pines early.

Woods is making his first competitive start of the year this week at the Farmers Insurance Open, and it will be his first official start on the PGA Tour since last year's event. He missed nearly all of 2017 because of a back injury before returning with a T-9 finish last month at the Hero World Challenge.

But the South Course at Torrey Pines is a far different test than Albany, and the Westgate Las Vegas SuperBook lists Woods as a -180 favorite to miss the 36-hole cut. It means bettors must wager $180 to win $100, while his +150 odds to make the cut mean a bettor can win $150 with a $100 wager.

Woods is listed at 25/1 to win. He won the tournament for the seventh time in 2013, but in three appearances since he has missed the 36-hole cut, missed the 54-hole cut and withdrawn after 12 holes.

Here's a look at the various Woods-related prop bets available at the Westgate:

Will Woods make the 36-hole cut? Yes +150, No -180

Lowest single-round score (both courses par 72): Over/Under 70

Highest single-round score: Over/Under 74.5

Will Woods finish inside the top 10? Yes +350, No -450

Will Woods finish inside the top 20? Yes +170, No -200

Will Woods withdraw during the tournament? Yes +650, No -1000

Monahan buoyed by Tour's sponsor agreements

By Rex HoggardJanuary 24, 2018, 12:27 am

SAN DIEGO – Farmers Insurance announced on Tuesday at Torrey Pines a seven-year extension of the company’s sponsorship of the Southern California PGA Tour event. This comes on the heels of Sony extending its sponsorship of the year’s first full-field event in Hawaii through 2022.

Although these might seem to be relatively predictable moves, considering the drastic makeover of the Tour schedule that will begin with the 2018-19 season, it is a telling sign of the confidence corporations have in professional golf.

“It’s a compliment to our players and the value that the sponsors are achieving,” Tour commissioner Jay Monahan said.

Monahan said that before 2014 there were no 10-year title sponsorship agreements in place. Now there are seven events sponsored for 10-years, and another five tournaments that have agreements in place of at least seven years.

“What it means is, it gives organizations like the Century Club [which hosts this week’s Farmers Insurance Open], when you have that level of stability on a long-term basis that allows you to invest in your product, to grow interest and to grow the impact of it,” Monahan said. “You experienced what this was like in 2010 or seen other tournaments that you don’t know what the future is.S o to go out and sell and inspire a community and you can’t state that we have a long-term agreement it’s more difficult.”

Events like this year’s Houston Open, Colonial in Fort Worth, Texas, and The National all currently don’t have title sponsors – although officials at Colonial are confident they can piece together a sponsorship package. But even that is encouraging to Monahan considering the uncertainty surrounding next season’s schedule, which will include the PGA Championship moving to May and The Players to March as well as a pre-Labor Day finish to the season.

“When you look back historically to any given year [the number of events needing sponsors] is lower than the typical average,” Monahan said. “As we start looking to a new schedule next year, you get excited about a great schedule with a great group of partners.”
