Everest Base Camp Weather
When contemplating a journey to Everest Base Camp, we often receive questions regarding the anticipated weather conditions and amount of rainfall. Although such information is undoubtedly valuable, it merely provides a fraction of the overall picture when it comes to advising climbers on their preparations.
Long Term (10 Days) Rain Forecast for Nepal
Despite the presence of a unique local weather system in the Himalayas, the most dependable method to anticipate rainfall at Everest Base Camp is by referring to the 10-day precipitation forecast. To gauge the expected rainfall for the upcoming week in relation to typical weather patterns during that time, simply scroll down to the map located at the bottom of this page.

The overlooked factor that significantly influences how climbers handle the weather at Everest Base Camp is altitude. Unless someone has personally experienced the coldness at high altitudes, it's challenging to effectively convey the true impact of altitude on one's perception of coldness without delving into complex explanations from biologists about how the body reacts to oxygen-deprived environments. Nevertheless, we will attempt to provide a simplified explanation.
Most readers are likely aware that the air's composition at altitude is essentially the same as at sea level, with oxygen comprising slightly less than 20% of the inspired air. However, as individuals ascend, the pressure exerted by the air above them decreases due to the reduced column of air between the outer limits of the Earth's atmosphere and their location. With the diminishing weight of air, the force that holds air molecules together weakens, resulting in thinner, less dense air. In simpler terms, we describe this phenomenon as a decrease in air pressure.
Why Everest Base Camp has only half the oxygen you're used to
Depending on one's location, normal sea level air pressure can be described as 1 atmosphere or 1,000 mbar. As one reaches Everest Base Camp at an elevation of 5,364m, the air pressure typically drops to around 480 - 520 mbar, approximately half of sea level pressure or half an atmosphere. Consequently, the density of the inhaled air at Everest Base Camp is roughly half that of sea level, resulting in approximately half the number of inspired oxygen molecules per breath.
Unless the breathing rate is significantly increased, the body operates with insufficient fuel supply. It may be worth noting that climbers might find it interesting to learn that Diamox (acetazolamide) artificially enhances the respiratory rate by acidifying the blood. This action prompts the chemoreceptors in the neck to signal the hypothalamus, activating the autonomic respiratory system to breathe more frequently and eliminate excess accumulated CO2, ultimately increasing oxygen intake.
However, climbers should also be aware that it is not essential to artificially induce this heightened respiration rate if they understand the requirements. Through practised breath control techniques (non-autonomic), climbers can voluntarily increase their breathing rate. It is important to note that this is not possible during sleep. As long as the climber does not experience an oxygen debt during daytime exposure to the highest elevation of the day, hypoxia is not expected during reduced respiration during sleep.
The Demand for Oxygen in Cold Climates
The thermoregulation process in mammals is highly resource-demanding, particularly in environments with significant deviations from temperate zones. In cold regions, the body relies on an ample oxygen supply to generate heat in the skin, which happens to be the largest organ in the human body. However, due to reduced muscle activity resulting from a limited fuel and oxygen intake, the body fails to produce sufficient heat by-product necessary to maintain the required skin temperature. Consequently, a challenging dilemma arises where our bodies must make a crucial decision between sustaining vital organs (such as the oxygen-hungry brain) with fuel and allocating a significant portion of the scarce oxygen supply to elevate skin temperatures.
The Body's Response to Low Atmospheric Oxygen Levels
As expected, the body's response to these requirements primarily consists of two main aspects: i) significant narrowing of the small blood vessels supplying the skin, with the most noticeable impact occurring in the extremities such as the hands and feet, and ii) reduction in the allocation of resources to processes like digestion and higher brain functions, resulting in decreased IQ and lower fuel demands. Some mountaineers have made claims that are challenging to verify, suggesting that without supplemental oxygen at Everest's summit, the diminished mental capabilities of an average adult are roughly equivalent to those of an average 6-year-old, thereby making complex decision-making nearly impossible.
Therefore, it is crucial for climbers to comprehend that despite the seemingly moderate temperature of minus 8 degrees Celsius that can typically be anticipated at the summit, when coupled with the effects of low oxygen and wind chill, meticulous planning of clothing strategies becomes a matter of utmost importance. We are more than happy to provide guidance and advice on this matter through email correspondence.
Seasonal Weather Patterns at Everest Base Camp
Everest Base Camp experiences distinct seasonal weather patterns. The most popular climbing seasons are spring (April-May) and autumn (September-October) due to relatively stable weather conditions and milder temperatures. These months offer better visibility and lower risk of storms. Conversely, climbers tend to avoid the summer monsoon season (June-August) and harsh winter (December-February) due to heavy rainfall, high humidity, and extreme cold, making climbing challenging.
The Yoga retreat camp is nestled in Nagarkot, a tranquil village in the Bhaktapur district, about 25 km from Kathmandu. The drive from Kathmandu takes around 2 hours. This peaceful location offers breathtaking views of the Himalayas and is surrounded by lush green hills, making it the perfect retreat for those seeking peace and a connection with nature. The retreat features a blend of daily yoga, meditation, sound healing sessions, and hikes in the nearby hills.
