Weather in Warsaw in July
Poland · 20-year averages, July
A good month. July is a solid month to be in Warsaw. Highs average 25.8 °C, lows 15 °C, and rain falls on 14 days — nothing in the month is working against you.
July ranks 5 of 12 in Warsaw: past the worst of the year but short of September, which is the month to book if the dates are open.
This is persistent light rain rather than storms: 14 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 35.6 °C and the coldest night fell to 7.6 °C, and the wettest single day dropped 33 mm — roughly 43% of the month's rain in one day.
July is moderately variable: 14 mm in the driest year against 239 mm in the wettest, around an average of 76 mm. Roughly two Julys in three land near that average, and the third does something else entirely.
Wind is light at 9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 67%.
How July sits in the year
Temperatures hold steady either side: 23.1 °C in June, 25.8 here, 25.8 in August. Nothing about the timing within the month matters much.
Daylight in July
July is at or near the longest days of Warsaw's year: 16.3 hours of daylight, losing 1.1 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
An inland climate
With no coast nearby, the year swings a fair way — 32.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Warsaw versus nearby
If Warsaw is one option among several, the nearby comparison is worth making. Kraków is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Gdańsk is close enough to be a coin toss — 4.6 °C cooler, the same number of rain days.
So: July works, with September the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
