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 52.25, 4.25, 19 km (12 miles) from the center of The Hague. A frost here means a low at or below 0 °C (32 °F).
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 few hundred feet away does not. No table can know that about your garden. Your own logged frosts eventually can.
