Weather in Gdańsk in July

A good month. July is a solid month to be in Gdańsk. Highs average 21.2 °C, lows 15.7 °C, and rain falls on 14 days — nothing in the month is working against you.

July ranks 3 of 12 in Gdańsk. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

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: it never really gets hot: not one day in an average July reaches 30 °C; the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 31.6 °C and the coldest night fell to 11.1 °C, and the wettest single day dropped 51 mm — roughly 59% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 154 mm against 21 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 86 mm average is a reasonable planning figure, not a promise.

Wind is light at 13.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 18.5 °C in June, 21.2 here, 21.6 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Gdańsk's year: 16.7 hours of daylight, losing 1.2 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 17.5 °C in July — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. This is the warmest the water gets all year.

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 Gdańsk versus nearby

If Gdańsk is one option among several, the nearby comparison is worth making. Warsaw is close enough to be a coin toss — 4.6 °C warmer, the same number of rain days. Szczecin is close enough to be a coin toss — 2.1 °C warmer, the same number of rain days.

So: July is effectively as good as it gets here — 1 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
