Best time to visit Warsaw

Warsaw is a city of two halves. September scores 83 and January scores 21 — a 62-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. The good window runs May to September — 5 months within ten points of the best.

July is the warmest month at 25.8 °C and January the coolest at -0.9 °C — a 26.7 °C spread across the year. At the other end, 118 nights a year fall below freezing: the winter here is a real one.

There is a real wet season here. May to July carry the rain — up to 14 wet days in a month — while March, April and October drop as low as 9. That 5-day gap is the biggest single difference between a good month and a bad one in Warsaw, and it moves further than the temperature does.

Daylight swings hard — 16.7 hours at midsummer against 7.8 at midwinter. That 8.9-hour difference changes how much fits into a day more than the temperature does.

The three strongest months are September, August, June. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
