Estimates only
Frost dates on this site are probabilities from 1991–2020 weather records at the nearest station. They are not a forecast. Frost can and does happen after the last frost date and before the first frost date. Planting dates are general guidance built from university extension publications and may not suit your site, soil, varieties or weather.
