In the spring gardeners often ask – will there be frost tonight in the UK? With over 50 years of historical daily temperature records and GIS mapping technology accurate to 1km, this tool provides a detailed view of frost likelihood, including estimates for air, light, and hard frosts, and a planting risk prediction tailored to your postcode location.
