I am an early-morning golfer. What is the justification for frost delays?
Keep in mind that a foursome typically takes several hundred footsteps on each green, so even allowing just a few groups to play when frost is present can be very damaging to the greens, as well as to the rest of the golf course. It is not completely understood when frost will cause damage, so the decision to keep traffic off the course must be made conservatively to protect the condition of the course. For this reason, golf facilities are wise to delay starting times in the morning until frost has completely melted.
Here is the Definition on frost and what causes it:
Frost is the solid deposition of water vapor from humid air. It is formed when the temperature of a solid surface is below the freezing point of water and also below the frost point.
