Fishing Seasons


The fishing season in Mongolia legally opens on June 15th and closes November 1.

Fish Mongolia’s season runs June through August.

The June opener coincides with the post-spawning period which tends to end in May.  By June, wild flowers blanket the stream shores and the taimen begin feeding aggressively.  Over the past few years, our ‘spring’ taimen season has been exceptional with the guides frequently reporting double-digit days.   Taimen hit hard on the surface striking anything from stimulators to large mouse patterns.  Watching a taimen charge a fly in gin clear water after a stealthy presentation is quite an experience.  

Autumn comes early to this part of Mongolia.  By the end of August, the weather can already be getting chilly.  The herders are busy cutting hay and the trees are just getting a bit of gold.  This time of the year is generally not about numbers, but quality.  For some reason, the really big fish often show up as they go through their last bout of aggressive feeding before winter.  The ger fires are warm and the fishing can be epic.

Our Fish Mongolia season wraps up by the end of August.

If you want to fish in September and October, head over to our eastern Mongolia operation, Mongolia River Outfitters. This lower elevation river is located about 800 kilometers to the east.  Over there, the fishing season just gets started in September and extends right through October.

We work hard to select the best times for weather and water.  That’s why we operate on two different rivers throughout the five month fishing season.  However, these are truly wild and remote rivers susceptible to flow fluctuations.  Precipitation can come at any season on these wild rivers and weather has become increasingly difficult to predict.

Although perfect weather and water conditions are never guaranteed, the skies are normally bright and sunny with crystal clear water conditions.  Any month of the year, you might experience a snow flurry and bright sunny “short sleeve” weather all in the same day.  Of course, rain can happen anytime.  However, mid-summer is historically when the risk of rain and blown out water is highest.  The great thing is… We’ve caught some of the largest fish ever when the river has color and this stream tends to drop and clear very quickly.
