When to plant pumpkins in Starogard Gdański

The Starogard Gdański dates are calculated from the observed last spring frost — a 2016–2025 mean of 26 April — rather than from a latitude estimate or a national calendar. The frost-free season here averages 204 days.

Season anchorobserved 2016–2025

Last spring frost: 26 April · latest 14 May

First autumn frost: 16 November · earliest 21 Oct

Frost-free season: 204 days · 10 complete years

These come from the ERA5 reanalysis on a roughly 9 km grid, so they describe the area rather than your plot. A hollow, a frost pocket or an exposed site regularly runs several degrees colder, so use the cautious date for a decision you cannot undo.
