Traveller notes on Uludağ in September
Notes from nearby Istanbul (102 km away)
Uludağ doesn't have its own notes for September yet — these are about Istanbul, close enough to share the season.
Istanbul in September reads well on the forum: cooler than August, pleasant and mostly sunny, with maximums around 25–27°C through the middle of the month and only about five wet days across it. Late September turns cooler and can bring rain, so the standing advice is layers, a light jacket for the evening and an umbrella held in reserve. The one thing September does not deliver is quiet — it is still high season, and regulars point out that Istanbul is busy essentially year-round.
Other months in Uludağ
Uludağ's forum calls January reliably snowy and cold, good for first-time skiers thanks to plentiful instructors and easy equipment hire. Regulars are honest that snow conditions can't be predicted far in advance — the standard advice is to decide which slopes to ski a day or two out rather than booking blind — and that late January, coinciding with school holidays, brings peak prices.
