Het weer in Uludağ (Uludağ) in september

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.

Uludag-forum threads on an April visit describe snow as genuinely usually still present mid-month, posters calling it iffy for actual skiing as the season winds down. Regulars call one visitor's own trip genuinely past the ski season, the poster naming a snowmobile ride and crisp mountain air as the real consolation instead. Posters call another April visitor genuinely lucky with fresh snow, several regulars naming this the reason results vary so much year to year this late. Regulars call the teleferik genuinely unreliable by April, several threads naming only a few chairlifts as still operating this late in the season. Posters recommend checking current lift and cable car status before an April trip, several regulars calling this standard given how much conditions can shift by mid-month. The record: 8.1C days, -1.7C nights, an extraordinarily high 94.8mm across nearly 14 days and 73 percent humidity.

Uludag-forum reviews on a June visit describe the mountain as genuinely free of cover by this point, posters calling it a solid stretch for real walking and hiking regardless of the resort's winter reputation. Regulars call conditions here surprisingly cool for summer, several posters reporting temperatures considerably lower than what Bursa below is experiencing the same day. Posters recommend the cable car ride up as a real highlight on its own, views considered genuinely worthwhile even without a specific hike planned. Regulars call barbecue spots among the trees a local favorite, several posters describing a picnic lunch as a standard part of a June day trip. Posters recommend real layers regardless of the warm valley below, mountain air here delivering a genuine chill even in June. The record: 16C days feeling like 15C, 6.9C nights, an extraordinarily high 100.4mm across over 13 days and 71 percent humidity.

Uludag-forum threads on a May visit describe early in the month as still carrying real leftover cover at the summit, posters calling this a genuine holdover from winter rather than anything unusual. Regulars call conditions at the top cold and capable of turning wet, real layers essential regardless of how mild Bursa feels. Posters describe the mountain as shifting character through May, transitioning from its winter identity toward a nature and trekking destination. Regulars call winter tires unnecessary this time of year, roads considered safe for standard vehicles by May. Posters recommend checking cable car and trail status before planning activity, conditions at elevation shifting faster than the base suggests. Regulars call the park still worth the trip regardless of exact timing, real forest and mountain scenery on offer throughout. The record: 11.8C days feeling like 10C, 2.4C nights, an extraordinarily high 124.5mm across 17 days and 75 percent humidity.

Uludag-forum threads on skiing in Turkey confirm the season typically runs from around December twentieth through March twentieth, making March genuinely the tail end rather than the core of the window. Posters call Uludag the country's most established winter resort, reachable in around forty minutes from Bursa along a well-maintained road. Regulars describe average annual accumulation as reaching several meters under a normal winter, though posters call March conditions specifically capable of running icy in the morning and softening to something sticky by afternoon. Posters recommend an early start for firmer conditions before the day's warmth sets in. Regulars call access here generally reliable compared to more remote alternatives, a real plus for anyone based in Istanbul. Posters recommend checking current lift status before a late-March trip. The record: 3.4C days feeling like 0C, -5.6C nights, an extraordinarily high 109.7mm across nearly 15 days and 76 percent humidity.
