Weather in Szczecin in September

Prime time. September is about as good as Szczecin gets. Highs average 19 °C, lows 9.7 °C, and rain falls on 10 days — nothing in the month is working against you.

September is the highest-scoring month of the twelve. The nearest rival is June, and the month at the other end of the year is January.

Rain on 10 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 September reaches 30 °C. Across the twenty years measured, the hottest September day reached 30.3 °C and the coldest night fell to 2 °C.

September is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest September on record still delivered 123 mm against 18 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 52 mm average is a reasonable planning figure, not a promise.

Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 4.3 °C cooler than August, with October dropping another 6.2 °C. The first week and the last are not the same trip.

Daylight in September

12.8 hours of daylight, losing 2.1 hours across the month. That is between Szczecin's extremes of 17 and 7.5 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 27.3 °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.

September in Szczecin versus nearby

If Szczecin is one option among several, the nearby comparison is worth making. Berlin is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Malmö is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: September is the answer for Szczecin. If it is booked out or priced out, June is the next best thing at 1 points behind, and January is the month to keep off the shortlist.
