Where these numbers come from
Modeled, not measured. No weather station stands behind these dates. They come from ERA5, a reconstruction of the world’s weather from 1991 to 2020 made by ECMWF, Europe’s medium-range weather forecasting agency, for the EU’s Copernicus program, and read here through Open-Meteo. They are the model’s daily lows for the point at 39.25, 121.75, 38 km (23 miles) from the center of Dalian. A frost here means a low at or below 0 °C (32 °F).
The model’s point for Dalian itself lies over the sea, where the water keeps the nights milder than on land, so these dates come from the nearest point over land, the one beside it.
A weather model sees the land in squares about 25 km (16 miles) across, so it can miss what sets one garden apart from the next: a frost hollow, a hillside, a lakeshore, a city’s own warmth. The Milpa planner reads these same numbers for a garden here and grades them A good hunch.
Cold air also pools in low ground on the clear, still nights when frost happens, so a hollow can freeze while a slope a hundred meters away does not. No table can know that about your garden. Your own logged frosts eventually can.
