Kyrgyzstan gets cold in September 2026!? Pack plenty of warm clothes for your trip

Salamatsyzby! This is Sugi from ASHU TRAVEL, scenic journeys across Central Asia!

An important heads-up for anyone coming to Kyrgyzstan in September.

I checked the forecast as of August 30, 2026, and this September looks set to be quite cold, especially in the highlands.

While some days in Bishkek are forecast to go above 30°C, mornings and evenings at Song-Kul and Jeti-Oguz may drop below freezing on some days.

Even within Kyrgyzstan, Bishkek and the highlands are in completely different seasons.

Don’t assume “it’s September, so autumn clothes will do.” Please pack warm gear as if you were preparing for winter in Japan!

How warm is it in September?

First, here’s a summary of average September temperatures and the forecast range for the month.

The highs and lows here are not record highs and lows, but the “average daily high and average daily low” for September.

Bishkek

For 1991–2020, the average high is 25.6°C and the average low is 10.9°C. Highs and lows for 1991–2020, Japan Meteorological Agency ClimatView

Song-Kul lakeshore

Based on 2009–2025 statistics, the average high is 11.7°C and the average low is 2.7°C. On average there are 7 days below freezing in September, and the lowest temperature recorded in this period was −6°C. Note that these are location-based statistics compiled from past weather data, not readings from an official station on the lakeshore. Song-Kul September normals.

Around Jeti-Oguz

I couldn’t find published official average highs and lows for the exact mountain-side location of Jeti-Oguz.

At the nearby Kyzyl-Suu station, the 1991–2020 average high is 20.5°C and the average low is 7.2°C. The monthly mean of 13.8°C also matches the official normal on the Japan Meteorological Agency’s ClimatView. Highs and lows for Kyzyl-Suu, Japan Meteorological Agency ClimatView

*In this article, “Jeti-Oguz” refers to the surrounding mountain side, including the red rocks and the resort area. Lower-altitude places such as the village or Kyzyl-Suu may be a few degrees warmer than the figures shown here.

Bishkek stays hot until mid-month, then turns to autumn by the end

In Bishkek, daytime temperatures are forecast to be around 25–30°C until about mid-September.

The high on September 6 is 31°C. Short sleeves may be just right during the day.

However, temperatures start dropping around the 25th, and from the 26th onward the forecast shows highs below 20°C.

Morning and evening lows also fall to around 6–9°C by the end of the month.

Temperatures change quite a lot between the first and second half of the month, so if you’re coming in late September, you’ll need a jacket even just for your stay in Bishkek.

For the forecast, I used AccuWeather’s monthly forecast for Bishkek.

Song-Kul: around 0°C in the mornings and evenings from mid-September

On the Song-Kul lakeshore, the September average is a high of about 12°C and a low of about 3°C.

Even in early September, mornings and evenings drop to 3–7°C. From around the 15th, lows hover around 0°C, and −2°C is forecast for the end of the month.

On top of that, Song-Kul sits at about 3,000 m above sea level.

When the wind blows, it feels much colder than the actual temperature. To be safe, be prepared for rain, sleet, or even snow.

There’s no 30-day forecast available specifically for the Song-Kul lakeshore.

So I took the September monthly forecast for Kyzart, the gateway to the lake, and adjusted it for the lakeshore’s altitude of about 3,000 m and for September normals.

Song-Kul’s September normals are an average high of 11.7°C and an average low of 2.7°C. Song-Kul’s September climate data shows an average of about 7 days below freezing in September.

Don’t let your guard down, even if it’s a little warm during the day.

If you’re heading to Song-Kul, prepare for winter, not autumn.

Jeti-Oguz: −5°C forecast in the second half of the month

On the mountain side around Jeti-Oguz, the September average is a high of about 13°C and a low of about 0°C.

From September 9 onward, there are more and more days with lows below freezing.

Lows at the end of the month are −3 to −5°C. September 30 is forecast at a high of 9°C and a low of −5°C.

When it gets this cold, a light jacket alone won’t be enough. You’ll need a down jacket, gloves, and a warm hat.

Note that AccuWeather’s monthly forecast for Jeti-Oguz is based on a registered point on the mountain side, near the red rocks and the resort area.

Lower places such as the village or Kyzyl-Suu may be a few degrees warmer, but you’ll still need warm clothing in the mornings and evenings.

Daily forecast for September 2026

This is the daily forecast as of August 30, 2026.

All values are shown as “high / low (°C).”

Treat the figures for the second half of the month as a “trend”

I’ve listed detailed figures here, but there’s no way to accurately predict temperatures 30 days ahead at this point.

A normal weather forecast is reliable for about 10 days ahead.

Beyond that, and especially for the daily forecast for late September, please read the numbers as “a trend toward colder weather in the second half of the month” rather than exact temperatures for each day.

Be sure to check the latest forecast again 3–5 days before you leave.

Warm gear we’d like you to bring to the highlands

If you’re visiting Song-Kul or Jeti-Oguz in September, please bring the following.

• Down jacket
• Warm base layers such as HEATTECH
• Fleece or sweater for layering
• Warm hat that covers your ears
• Gloves
• Thick socks
• Disposable hand warmers
• Wind- and rain-proof outer jacket

The key is layering that you can take off and put on, rather than relying on one thick piece of clothing.

It’s hot in Bishkek. It’s cold in the highlands. And even in the highlands, it’s warm in the sun but gets cold fast once the sun goes behind a cloud.

We recommend short sleeves or a light long-sleeve top, with a fleece, down jacket, windbreaker, and so on that you can layer to adjust.

Even while riding, it feels warm when the sun is out.

But it gets cold quickly when clouds roll in or the wind picks up. Keep your warm layers somewhere you can reach them right away.

Prepare so you won’t be saying “I wish I’d brought it”

September in Kyrgyzstan is a relatively easy season for travel, once the summer heat has eased.

In the highlands, however, mornings and evenings are already close to winter cold.

If you judge by Bishkek’s warmth alone and think “I’ll be fine,” you’ll be in for a surprise when you reach Song-Kul or Jeti-Oguz.

So you won’t end up thinking “I wish I’d brought my down jacket…” once it gets cold, pack a little extra warm gear.

On the ground, we’ll also keep an eye on the weather and how everyone is feeling, and guide you at a comfortable pace.

If you’re unsure what to wear or bring, feel free to ask ASHU TRAVEL.

Prepare well and enjoy Kyrgyzstan in September!
