Good to know
What temperature counts as a frost?
Ground frost can form when the air is around 3 to 4 °C, because the ground cools faster than the air. Air frost is 0 °C or below, and a hard frost is roughly -2 °C or colder.
When should I protect tender plants?
Cover or move tender plants and pots before dusk on any night forecast near or below freezing. Frost is worst on clear, calm nights.
Where does the forecast come from?
Open-Meteo, using the overnight minimum temperature for your location across the next five nights.
