Weather
Affects Golf Ball Flight
Golf is played
in many different types of weather. The type of weather affects
how
far
the ball
travels
and its amount of spin. Knowing how the weather conditions affect
your ball, therefore, is necessary to making correct club selections.
The
trajectory of a golf ball and the distance it travels depends on
its initial trajectory, speed and spin, as well as what it's moving
through (air). The air is not always the same. It varies in temperature,
pressure, humidity and density. If there were no air whatsoever,
the golf ball would not travel far. Likewise, if a ball is hit in
air with no spin, it will not travel far. Check out the graph below
of a golf ball hit with a driver under 3 different conditions.
Note first
of all that the horizontal and vertical scales are quite different
so as to depict clearly the differences in the conditions.

The spin
on the ball creates lift which increases the height reached and
increases the time of flight so that the ball travels further.
If
there were no air, spin wouldn't matter at all. If the air is changed
(pressure, temperature, density) the height and distance travelled
will change.
Try out
my Distance
Calculator. You can input different conditions to see how they
affect your tee shots.
Under
normal conditions, the air does not change very much, but the
amount can be significant and should be taken into account,
otherwise your ball will fall too short or too long of its mark.
Below is a table of distances for a 5-iron and Driver under
different atmospheric conditions.

Note
that temperature is in degrees Celcius. On the Fahrenheit scale,
the temperatures would be 41, 68 and 95 degrees respectively.
The distances also depend on the air pressure which not only
depends on temperature and humidity but also on altitude. Hot
and humid results in the ball travelling further.
