Ground frost

A ground frost occurs when ice forms on the ground, objects or trees, where the surfaces have a temperature of freezing or below, causing water to freeze.

Weather stations measure the ground temperature with a thermometer that’s 5cm from the ground. When the temperature at this point hits 0C, then a ground frost has been recorded.

However, because the ground cools quicker than the air around a metre above, it is possible for a ground frost to occur without an air frost.

There’s also something called a grass frost, which is where natural surfaces such as grass freeze when man-made surfaces such as tarmac and concrete don’t. This type of frost is of most interest to gardeners.

Air frost

An air frost occurs when the depth of air above the ground has increased to the level at which weather stations measure air temperature – which is 1.25 metres in the UK.

So, effectively the layer of cold air near the ground hitting 0C or below has become thicker and thicker as more heat energy is lost to space and the temperature falls.

Hoar frost

This is another type of frost that we typically associate with a frosty morning and has a white appearance.

A white frost, consisting of little blobs of ice, occurs when dew has formed and then subsequently frozen when the temperature hits 0C.

A feathery frost, consisting of feathers and needles, occurs when the temperature has already reached 0C and then dew forms.
