Frost dates for Yekaterinburg, Russia

Half of years have their last spring frost by May 18, but 1 year in 10 still frosts after May 30.

A frost date is really a percentile, here from 30 years (1991 to 2020) of a weather model’s daily lows near Yekaterinburg: in about half of years a frost still comes after the median date. Both numbers are below, so you can choose the risk yourself.

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 56.75, 60.75, 15 km (9 miles) from the center of Yekaterinburg. 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 hundred meters away does not. No table can know that about your garden. Your own logged frosts eventually can.
