On Wednesday, a record 274 climbers successfully reached the peak via the southern route from Nepal, marking the highest single-day summit total ever recorded on that side of the mountain.
The figure surpasses the previous record of 223 climbers set on May 22, 2019, and the final tally may yet climb higher, as some climbers had not yet reported back to base camp to complete their records.
The surge was shaped by an unusual confluence of factors. Good weather conditions and a large backlog of climbers waiting to ascend played a key role, according to Rishi Bhandari, secretary general of the Expedition Operators Association of Nepal.
This year’s Everest climbing season began late because of risk from a large serac, a block of glacial ice, hanging over the key route to the summit, forcing expeditions into a narrower window and concentrating activity into fewer summit days.
Adding to the crush, China did not issue permits for the northern side of the mountain this year, effectively closing the Tibetan route and funneling all climbing activity through Nepal. In 2019, the previous record year, the numbers were split between both sides of the peak.

Nepal has issued 494 climbing permits for this season, with each climber paying $15,000 for the opportunity. With an equal number of Sherpa guides accompanying expeditions, the human presence on the mountain is substantial.
The day also witnessed a cluster of individual milestones. Veteran Sherpa guide Kami Rita Sherpa reached the summit for the 32nd time, extending his own world record, while Pasang Dawa Sherpa completed his 30th ascent. Lhakpa Sherpa reached the top for the 11th time, retaining the record for the most summits by a female climber.
The record has reignited debate over overcrowding on the world’s highest peak. Overcrowding has been a growing concern on Everest for years; a now-infamous 2019 photograph showed a long queue of climbers on an exposed ridge in the so-called “death zone,” with roughly 320 people waiting to reach the top.
Not everyone sees cause for alarm, however. Expedition organiser Lukas Furtenbach of Austria-based Furtenbach Adventures argued that congestion can be managed with sufficient oxygen and logistics, comparing Everest to busy Alpine peaks and suggesting that 274 climbers in a single day is “not extreme.”
Strong winds are forecast for later in the week, likely bringing the 2026 spring season’s main summit window to a close.
