Often on the lake the weather can be unsettled, with winds coming from every direction over time. Some of these winds are famous, and actually have names. For example, the Barguzin is a crosswind that rises up out of the valleys to the east of the lake. Then there is the Sarma wind, which can often reach hurricane levels of 40 meters per second. Most people prefer the lighter Selenga winds, which will bring up warmer air from the Mongolian steppe-lands to the south. Finally, when there is fog shrouding the Khamar-Daban Mountains, you will often get a Kultuk wind blowing in from the southwest.
