Frost delays and winter golf
You show up for an 8:00 a.m. tee time on a crisp December morning and the starter says there's a frost delay. It can be frustrating, but there is a real reason for it. Here is why courses wait, and how to plan winter rounds so frost doesn't catch you out.
Why frost delays exist
When frost forms, ice crystals form inside the grass blades and make the plant stiff and brittle. According to the USGA, footsteps or cart tires on frosted turf push those ice crystals through the plant's cell walls and rupture the cells.
The damage doesn't show up right away. Over the next few days, footprints and tire tracks turn brown as the damaged grass fails to recover. If only the leaf blades are hurt, the grass grows out of it. If the plant's growing point (the crown) is damaged, recovery can take months. Putting greens are mowed very short, so they are the most vulnerable.
One foursome walking across a frosted green can leave dozens of dead footprints, and the course has no way to know in advance exactly when damage will happen. So courses play it safe and delay play until the frost has completely melted.
How long do frost delays last?
There is no set length. It depends on how hard the frost is, how quickly the sun reaches the turf, and the air temperature. A light frost on a sunny morning may clear within an hour of sunrise. A heavy frost on a cloudy, still morning can delay play until late morning. Shaded greens and low spots are usually the last to thaw, and the course waits until they are clear.
When a delay hits, tee times usually shift back in order. That creates a backlog, so a 9:30 tee time can end up going off well after 10:00.
When frost is likely
Frost can form when the air temperature at eye level is in the mid-30s or even a little higher, because grass on a clear, calm night cools below the air above it. The setup to watch for is a clear sky, light wind and a low near or below freezing.
Dallas–Fort Worth averages about 29 freezes per cold season. December and January have average lows in the upper 30s, so frost delays are a regular part of DFW winter golf.
Planning a winter round
- Book late morning or early afternoon. Late morning through mid-afternoon is the warmest part of a winter day and avoids frost delays. In DFW, January's average high is in the mid-to-upper 50s.
- Watch the sunset. In December, DFW sunsets come around 5:20 p.m. Don't start an 18-hole round much after noon unless you play quickly. See sunset times by month.
- Call ahead on cold, clear mornings. The pro shop can tell you whether a delay is in effect.
- Mind the wind chill. A 50°F day with a 20 mph north wind feels far colder than a calm 45°F day. Winter wind usually comes with cold fronts.
- Dress in layers. A thin base layer, a vest or pullover and a windproof outer layer let you swing freely. Winter gloves and a warm hat between shots help a lot.
- Expect shorter distances. Cold air and a cold ball cost a few yards per club. See temperature and distance.
Frozen ground and dormant grass
Many Texas courses use warm-season grasses such as Bermuda on fairways, and these go dormant and turn tan in winter. Dormant grass is still playable, but it doesn't recover from damage until spring. That's why some courses keep carts on paths in winter even when the ground is dry. Frozen ground also means harder bounces and odd kicks. Expect more roll, and don't be surprised if an approach shot skips through a firm green.
Golf Weather Intelligence scores each tee time for temperature, wind and rain during the round, which helps you find the warmest, calmest window on a winter day.
