Does the ball fly further when it is 100 degrees than when it is 80 degrees? What is the impact of humidity? Is there any type of formula you have developed? I've felt I killed it before when it was 35 degrees and I didn't have to walk very far. Between 35 degrees and 100 degrees I am guessing there might be as much as a 20% difference in driver distance.

Really curious to hear what you guys think.
Frank Thomas, former technical director for the USGA, says that for every 10* difference in temperature we gain, or lose, around 2.5 yards of carry.

The ball carries further when it is humid. Many baseball players will tell you the ball carries further in humid conditions. In the summer, I know my teeshots carry further in Texas than in California.

I'll dig up the info I came across on the impact of humidity on carry provided it isn't already boxed up for an upcoming move.

Using Dave Tutelman's program "TrajectoWare Drive 1.0" came up with the following values:

Club Head speed = 95 mph
Angle of Atcck = 0
Dynamic Loft = 10.5

60 deg F = 209.6 yards carry
70 deg F = 210.1 yards carry
80 deg F = 210.6 yards carry
90 deg F = 211 yards carry

I would believe DaveTutleman way before Thomas. If you want to look further in the Engineering of golf equipment I would suggest that you go to the site:

Having problems posting, I'm getting kicked off the site; maybe its a sign:

I noticed that no one mentioned the 1% your ball flys for every 500' you are above sea level

How is your math?

I would be curious to find the reasoning behing the ball flying further in humid consitions. It seems to but I can't reason why considering the air is heavier with moisture. Or is this a golfing urban legend? :confused1

KAPLOWD 02-11-2008 12:25 PM
The air is lighter in humid weather. Just look at the barometric pressure, which measures the weight of air to push mercury up. It's usually lower when it's humid out, then when there are blue skies (high pressure). Now if it's raining, then the ball has to over come friction.

When the air temp is high and the humidity is like a gas not moisture.
As KAPLOWD said, the air will be lighter and the ball will stay up there
longer. When it's really hot like 90* and humidity is high like 70, balls
will have a bit longer carry. If temps are low like 50* and the humidity
is high, the air becomes more dense and the ball will not go as far.
