Weather in Qingdao in September

Prime time. September is about as good as Qingdao gets. Highs average 24.7 °C, lows 20.7 °C, and rain falls on 8 days — nothing in the month is working against you.

September ranks 2 of 12 in Qingdao. Only October scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 8 days, 2 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; the day barely swings — 4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 31.7 °C and the coldest night fell to 13.3 °C, and the wettest single day dropped 77 mm — roughly 101% of the month's rain in one day.

September is moderately variable: 12 mm in the driest year against 248 mm in the wettest, around an average of 76 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 12.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How September sits in the year

The month is on the way down: 2.8 °C cooler than August, with October dropping another 4.9 °C. The first week and the last are not the same trip. Rain has already shifted: 9 days fewer than August had.

Daylight in September

12.5 hours of daylight, losing 1.1 hours across the month. That is between Qingdao's extremes of 14.6 and 9.7 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 24.2 °C in September — warm enough to stay in as long as you like. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Qingdao versus nearby

If Qingdao is one option among several, the nearby comparison is worth making. Nanjing is the weaker option in September — 3.8 °C warmer, 1 day more rain. Shanghai is the weaker option in September — 3.5 °C warmer, 4 days more rain.

So: September works, with October the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
