Frost dates in Romania

Why frost dates vary across Romania

A national figure would be no use to anyone here. The growing season runs from 193 frost-free days at Iaşi to 287 at Constanţa — a difference of 94 days, which is the difference between one tomato crop and none. That is why every date on this site is calculated for one place at a time.

How to read the table

Last frost is the median date of the final spring frost: in half of the years on record the last frost fell before it, in half after. First frost is the median date of the first autumn frost, and season is the number of frost-free days between them. All three are measured at the 0 °C air-temperature threshold.

A median is a planning date, not a guarantee. Plant tender crops on it and you accept roughly a one-in-two chance of a later frost in any given year. Each town page shows the cautious date — safe in nine years out of ten — alongside it, together with the earliest and latest frost the record holds. Read how the figures are calculated.
