Everyone knows that playing golf at a high altitude will make your golf ball travel further as the air is less dense.
But did you know high humidity also causes your golf ball to travel further?
It is counter intuitive and the reason isn’t immediately clear. Surely the air is more dense causing more drag on the golf ball?
The answer lies in the make up of the air itself. Air is made up predominantly of nitrogen, oxygen and water vapour molecules. The nitrogen and oxygen molecules are heavier than the water vapour molecules.
A volume of air of high humidity contains more water vapour molecules than one of lower humidity and therefore weighs less and is less dense per cubic metre.
This leads to less drag on the golf ball which means it travel further in the air.
So ideally, if you were looking to play in conditions where your golf ball will travel the furthest, high on a mountain in high humidity would be perfect.
