Weather in Bursa in September
Turkey · 20-year averages, September
Prime time. September is about as good as Bursa gets. Highs average 29 °C, lows 16.5 °C, and rain falls on 6 days — nothing in the month is working against you.
September ranks 4 of 12 in Bursa: past the worst of the year but short of May, which is the month to book if the dates are open.
Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29 °C days and 16.5 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 13 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest September day reached 41.2 °C and the coldest night fell to 8.3 °C, and the wettest single day dropped 28 mm — roughly 60% of the month's rain in one day.
September is moderately variable: 1 mm in the driest year against 109 mm in the wettest, around an average of 47 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.
Wind is light at 8.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.
How September sits in the year
The month is on the way down: 4.4 °C cooler than August, with October dropping another 5.8 °C. The first week and the last are not the same trip.
Daylight in September
12.5 hours of daylight, losing 1.3 hours across the month. That is between Bursa's extremes of 15 and 9.3 hours, so days are long enough not to constrain the plan.
An inland climate
With no coast nearby, the year swings a fair way — 31.6 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
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 Bursa versus nearby
If Bursa is one option among several, the nearby comparison is worth making. Istanbul is close enough to be a coin toss — 3.5 °C cooler, 1 day more rain. Eskişehir is a better bet in September — 2.2 °C cooler, the same number of rain days.
So: September works, with May the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
