Temperature readings for official weather reports are typically taken in shelters about 1.5 metres above the ground to standardize measurements and reduce the impact of direct sunlight or surface radiation. This can lead to higher readings than the actual ground or grass surface temperature, where frost can form if the temperature drops to the freezing point or below, even if the official air temperature is reported to be above freezing.
