Frost delays
The decision to implement a frost delay varies among golf courses. Some courses choose to continue regular play, while others opt for a ""Frost Delay"" or use temporary greens. Frost delays typically push back tee times until the ground has warmed up enough to melt the frost. Factors such as clear skies, calm to moderate winds, cool temperatures, and local topography influence the occurrence of frost.
To reduce frost problems, golf course management may employ strategies such as running fans to blow air over the greens or removing trees that shade the greens, as shaded areas tend to have lower soil temperatures and more frost. In some cases, sprinklers may be turned on to melt the frost, but this carries the risk of creating a thin layer of ice if the temperature drops further.
Golfers are advised to check with the golf course regarding frost delays and dress appropriately for cold weather. Frost delays can cause frustration due to the backlog in tee times, but they are necessary to maintain the course's condition. It's important for golfers to respect the rules of frost delays and refrain from walking on the greens during this time.
While some golfers choose to play on frozen greens, it is generally not recommended as it can cause damage to the course and affect the playing experience. The ball's behaviour becomes unpredictable on frozen greens, and it may leave irreparable pitch marks. Additionally, ice accumulation on golf shoes can create indentations on the green's surface.

Turf damage
Frost delays are common during winter to prevent damage to the turf on golf courses. Frost is frozen dew that crystalizes on the grass, making it hard and brittle. Blades of grass are composed of 90% water, which is why they freeze so easily. Walking on frost-covered grass can cause the plant to break and the grass cell walls to rupture, hindering normal growth. This damage may appear as footprints and can make the surface of the green uneven. Severe turf damage can occur when the top layer of soil thaws while a deeper layer remains frozen. The thawed layer, which is saturated with water, becomes spongy, and walking on it can cause footprints and even shear off the roots as the turf moves above the frozen layer. This can result in weaker turf around the hole, which may last for several months.
Cart traffic has also been found to damage frost-covered turf, particularly on creeping bentgrass, annual bluegrass, and perennial ryegrass fairways. Maintenance equipment, such as mowing and rolling, can also harm the greens during frost. Golf courses may implement temporary greens or adjust their starting holes in the winter to address these issues.
To mitigate frost problems, running fans to blow air over the greens can be effective when the temperature is only a few degrees below freezing. Removing trees that shade the greens can also help reduce frost delays. It is important to note that the damage caused by foot traffic may not always be immediately visible, and the average golfer may not understand the importance of a frost delay.
In terms of temperature, frost typically begins to form at 4°C or lower, and grass can be permanently damaged if temperatures suddenly drop below 20°F (-6.7°C). However, it is challenging to determine when to allow play on greens with frozen soil, as the temperature can vary across the course. Shaded greens, for example, tend to be the last to thaw and are more prone to damage as golfers are eager to return to the course after cold spells.

Thawing and refreezing
Frost delays are a common occurrence on golf courses during the winter. Frost forms when the temperature of grass blades falls below freezing, causing air vapour to freeze onto the plant. This results in extremely brittle grass as the cell walls freeze. Walking or driving on frost-covered grass can cause severe damage, including puncturing leaves and rupturing grass cell walls, hindering normal growth. The damage may not be immediately visible, but it can cause the turf to become uneven and weaker, with brown patches appearing days later.
To prevent frost damage, some golf courses implement a "Frost Delay", postponing play until the ground has warmed up enough to melt the frost. However, this can cause frustration among golfers eager to return to the course after cold spells. Superintendents may also reroute play to greens with less shade, as shaded greens are typically the last to thaw and are more prone to frost damage.
In certain situations, golf courses may opt for temporary greens to allow play to continue during frosty conditions. Temporary greens provide an alternative playing surface, reducing the risk of damage to the regular greens. This approach allows golfers to enjoy their game while minimising potential harm to the course.
When the temperature is close to freezing, golf course staff may employ strategies such as using sprinklers on greens to prevent frost formation. However, this method carries the risk of creating a thin layer of ice if the temperature drops further. Additionally, fans can be used to blow air over the greens, helping to reduce frost issues when the temperature is only slightly below freezing.
During the thawing process, it is crucial to be cautious as this is when significant damage can occur to the greens. When the top layer of soil thaws while a deeper layer remains frozen, the thawed layer becomes saturated with water and spongy. Walking on this surface can cause severe turf damage, including shearing off roots and creating an uneven surface. Therefore, it is essential to exercise patience and allow the greens to fully thaw before resuming play.

Grass type
While I cannot find a specific temperature at which golf greens freeze, it is clear that frost and freezing temperatures can cause severe damage to golf greens. Frost delays are often implemented to prevent damage to the grass, which can be caused by walking on the frozen turf. This damage can cause the turf to become uneven and can result in weaker turf in the spring.
When it comes to grass type, there are several varieties that are more tolerant of cold temperatures and are therefore better suited for use on golf greens in colder climates. Here are some options:
Red Fescue
Red fescue is a popular perennial, cool-season grass variety used worldwide, and Canada is the largest supplier of this cold-weather seed. It has thin blades that grow tightly together, making it ideal for golf courses as it can withstand some foot traffic. It prefers dry, loamy soil that is slightly acidic. However, there are limited herbicide options for weed control with this grass type.
Chewings Fescue
Chewings fescue is a type of fine fescue that tolerates shade well and has high levels of endophytes, which help resist attacks from insects and other pests. It requires less nitrogen, water, and fertiliser than other grass types, making it a good choice for drier climates with less sun.
Tall Fescue
Tall fescue is a hardy, adaptable, and wear-resistant grass that is easy to care for and incredibly cold-tolerant. However, it is more susceptible to pests and diseases than fine fescues. It has thicker blades and can grow quite tall, averaging between 4 and 12 inches in height. While it can tolerate foot traffic, it is not recommended for areas with high levels of activity due to its bumpy surface.
Ryegrass
Ryegrass is a common cold-weather grass variety in Canada that can adapt to various environments, including sun and shade. It is often used to deter soil erosion in warmer climates. Ryegrass retains nutrients for longer than other cool-season grasses, enriching the soil for future growth. However, it is important to plant at the right time to prevent susceptibility to pests and diseases.
Zoysia Grass
Zoysia grass is known for its tolerance to cold temperatures relative to other warm-season grasses. It has deep, extensive roots that help it withstand drought conditions. While it needs less fertiliser and mowing than Bermudagrass, it may require dethatching due to thatch buildup. Zoysia grass provides a lush, green turf that can tolerate foot and hoof traffic, although it may take longer to recover from heavy traffic.

Golf ball behaviour
Frost delays are a common occurrence on golf courses during the winter. Frost forms when the temperature of grass blades falls below freezing, causing air vapour to freeze onto the plant. This results in extremely brittle grass as the cell walls freeze. Walking or driving on frost-covered grass can cause severe damage to the turf, including puncturing the leaves and shearing off the roots, which can result in weaker turf in the spring. Therefore, some golf courses implement a "Frost Delay", postponing play until the frost melts, while others choose to continue regular play or use temporary greens.
When playing golf in cold temperatures, the ball's behaviour is significantly affected. Firstly, the golf ball will not travel as far as it normally would, so golfers may need to use additional clubs to achieve the desired distance. Secondly, the swing's range of motion may be limited due to the cold, impacting the shoulder turn and total distance. Finally, golfers can expect reduced spin around the greens, as the firmer greens and moisture on the club or grass make it challenging to generate spin.
To compensate for the ball's reduced travel distance in cold temperatures, golfers can employ a "bump and run" technique, as seen in a golfer's account of playing in temperatures around 32°F (0°C). By utilising a bump and run approach, they were able to avoid the risk of a sky-high bounce that could send the ball careening off course.
Additionally, shaded greens tend to remain frozen longer than those exposed to sunlight, impacting ball behaviour. In such conditions, the ball is more likely to bounce off the frozen surface, resulting in unpredictable trajectories. This can lead to comical bounces on the uneven fairway or rough, making the game more challenging and unpredictable.
While some golfers choose to stay off the course during extremely cold weather, others embrace the unique experience it offers. Embracing the challenge of playing on frozen greens, golfers can expect their balls to create pitch marks, especially if the top layer is slightly softer. However, it is essential to be mindful of the potential damage to the course and follow any guidelines or restrictions implemented by the golf course management.

Frequently asked questions
Frost occurs when the temperature of grass blades falls below freezing, which is usually 32°F or 0°C. Frost can also occur at temperatures above freezing if the grass is cool enough relative to the air temperature.
Walking or driving on frozen grass can damage the turf by breaking the grass and rupturing cell walls. This damage may not be immediately visible but can result in footprints, uneven surfaces, and weaker turf that is susceptible to disease and weeds.
Frost delays can vary in length, ranging from 30 minutes to several hours. The duration depends on the severity of the frost and the measures taken to mitigate it, such as using fans or sprinklers to increase the temperature of the greens.
Some golf courses implement a "Frost Delay" policy, where play is rerouted to the holes with the least shade or to temporary greens. This allows golfers to continue playing while avoiding potential damage to the frozen greens.
Playing on frozen greens can significantly impact the game. The golf ball may bounce unpredictably, travelling much further than expected. Additionally, it is challenging to get tees into frozen ground, and the swing's range of motion may be limited due to the cold weather.
