Poland braces for a brief warm spell before rain and cooler weather arrive

A warm spell on Wednesday

The Institute of Meteorology and Water Management (IMGW) forecasts a short rise in temperatures on Wednesday, 21 October, before the weather turns. Maximum temperatures are expected at 14-15°C in the north and northeast and 20-21°C in the south. Cloud cover stays small to moderate for most of the country, with larger cloud and brighter spells confined mainly to the north and east. Weak rain or drizzle is possible in the northeast. Winds are mostly weak to moderate, with gusts of 55 km/h on the coast and 65 km/h in the Sudetes foothills, and up to 75 km/h in the Carpathian foothills.

Rain arrives overnight into Thursday

From the night of Wednesday into Thursday, cloud cover increases and rain moves in from the southwest toward the centre of the country. In the southwest the rain is forecast to be moderate at times, with 10-15 mm possible in places in Silesia. Minimum temperatures are mostly 8-11°C, around 13°C on the eastern coast, and 5-7°C in lower foothill basins. In the Sudetes, rain is expected to turn to sleet and snow at higher elevations. Gusts reach 55 km/h in the northeast and 70 km/h in foothill areas, while the high mountains could see up to 90 km/h early on, easing later.

Cooler days from Thursday

On Thursday, 22 October, cloud will be extensive and continuous, though the west may see larger breaks in the afternoon. Rain is expected in many regions, becoming moderate in a band from Pomerania through the centre to the south in the afternoon. Totals of around 15 mm are forecast in places, and up to 20 mm in the Carpathians. Maximum temperatures range from 10-11°C in the south and west to 15-16°C in the east. On Friday, 23 October, highs are expected at 11°C in the east to 15°C in the west, with only 7°C in foothill areas, and rain mostly in the north. Saturday, 24 October should stay at 13-14°C at most, with rain forecast in the west.

A brief rebound and a cold snap

Sunday, 25 October brings another short warm-up, with highs of up to 17°C in the south and 12-15°C in the rest of the country, and the sunniest weather concentrated in the south. Monday, 26 October turns colder, with 11°C in the northwest to 15°C in the southeast and only 7°C at the southern edges, and most of the rain falling in the south and centre. Tuesday, 27 October sees 10-11°C in the centre and east, 13°C in the north and west, and 5°C in foothill areas, with rain across most of the country apart from the west.
