The quietest and busiest months

In 2025, January was Poland's quietest month (5.8% of the year's tourist nights): average high 1.0 °C, average low −4.0 °C, 31 mm of rain. August was the busiest (13.9%): average high 24.7 °C, average low 13.8 °C, 61 mm of rain. The figures do not show that the weather makes a month busier or quieter, so we do not say it does.

What these figures are

One weather station stands for Warsaw; places nearby can differ, especially by height or distance from the sea. For the full picture of Poland, including regions and holidays, see our Poland page; for other places, the visual guides and golden hour by place.
