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.

The cautious column is calculated from the latest frost recorded in the period (12 May). Use it for tender crops you cannot re-sow.
The year in Gdańsk
What can move the date
Sow as early as the soil can be worked — peas hate heat and finish before midsummer. Give even the "dwarf" varieties netting to climb; they crop far better off the ground.
Final spacing: 8 × 45 cm. Soil: pH 6–7.5.
Direct-sow only once the soil holds 8°C or more — soil temperature decides germination, not the date.
