Which months are mildest at Poland?
Normal highs sit between 65°F and 85°F in June, July, August and September. Of those, September has the fewest days with rain (11).
That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost at Poland?
In Poland, the last spring frost (32°F) comes after May 3 in half of years and after May 16 in one year in ten; the first autumn frost comes before October 7 in half of years and before September 27 in one year in ten.
Frost-free in half of yearsFrost in 1 to 9 years out of 10Frost most years
- Last spring frost, half of years after
- May 31 year in 10 after May 16; 9 in 10 after April 23
- First autumn frost, half of years before
- October 71 year in 10 before September 27; 9 in 10 before October 23
NOAA puts the median frost-free season at 157 days, and the season without a hard freeze (28°F) at 183 days.
A hard freeze (28°F) comes after April 21 in half of springs and before October 22 in half of autumns.
The USDA's 2023 Plant Hardiness Zone Map puts Poland in zone 5b in ZIP code 04274, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, the station is in zone 6a: the coldest night of a typical year reaches −8°F (20 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Poland share this climate record?
2 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
