The typical last and first frost of your municipality and sowing and planting windows for 20 crops.
Frost, more than the calendar, decides when tender crops can go out and how late hardy crops can still be sown.
From 35 years of daily minimum temperatures (1991–2025) we find, for each year, the last day at or below 0 °C before July and the first from July. The typical dates are the medians. The late spring and early autumn dates are the worst year in ten.
Each crop has a general rule against those dates: for example peas can go in about six weeks to one week before the last frost, tomatoes about two to seven weeks after it. Crops that need a long season are cut off so they can finish before the first autumn frost.
Where frost is rare the page uses a typical calendar instead and says so.
They are for the municipality's centre and elevation. A valley, a slope or a garden near the sea can differ by weeks. Watch the frost forecast before planting out tender crops.
In one year in ten the last frost comes later than the typical date. Waiting until the late date lowers the risk.
Yes. The windows are general rules, not advice for a variety, soil or protection such as tunnels.

Tender crops (tomatoes, cucumbers and so on) are timed from the late last frost, because the model tends to run mild. The windows are general planting rules against the last and first frost, not advice for a variety or soil. The data is a model on a grid several kilometres wide and does not see frost hollows or cold-air drainage in your garden: a rise or a valley nearby can shift the dates by weeks. For the coming nights see the frost forecast.
