อากาศแอนดีจ็อน เดือนกันยายน

One traveler who spent a month touring Kyrgyzstan from mid-August to mid-September, including stops in Osh itself, specifically noted Osh gets quite hot - distinct from the much colder, more unpredictable conditions posters describe for the high-altitude trekking routes elsewhere in the country (Son-Kul, Sary-Mogul), where snow is a real possibility even in September and temperatures can swing from shorts-and-t-shirt one day to bundled up the next. For the city itself, rather than the mountain routes, day-to-day conditions in September are generally described as warm and stable.

There isn't much Andijan-specific forum chatter, but the broader Uzbekistan threads consistently rate October (alongside September) as one of the best months nationwide: pleasant low-20s C by day, almost no rain, and plenty of sunshine. The catch posters flagged again and again is how fast it cools once the sun sets - a quilted jacket or thick pullover becomes necessary for evenings even after a warm, bright afternoon. Layer up rather than pack for a single temperature, since the daily swing is the defining feature of this shoulder-season month.

Forum posters consistently name April as a much more comfortable month across Uzbekistan than the peak summer heat, though posters are direct that spring weather stays genuinely changeable and April remains a relatively wet month by the country's standards. Posters describe early April as commonly sunny but not hot, with rain on a handful of days rather than sustained wet stretches - one detailed 12-day April trip logged just 4 rainy days, only one of which lasted more than two hours. Posters generally recommend a light jacket or sweater for cooler evenings, with conditions warming further as April moves into May, a pattern posters describe applying across the country's Fergana Valley cities including Andijan alongside the more commonly covered Tashkent, Samarkand and Bukhara.
